Thanks for the replies. Robert, the main feed hasn't gone out. I'm off work on an injury, so I have time to kill. I was gonna go over the wire harness and fix any loose connections, and replace the main feed, since it looks shady to me. I plan on replacing that wire, along with the one for the ammeter (which I'm not sure I will use), and clean and/or replace any terminals that need it. The only addition I was gonna have was a graphic equalizer/amp, which is very small. The car will have no A/C, no power brakes, nor power steering. Manual windows and locks, as well. It's a 4-speed, too. Any tips or suggestions???

I swore it was in the archives but I could not find it either (& I have seen it there ). iirc on the bulkhead the 2 main in/out wires, the one "in" from the fusible link and the "out" wire to the alt you just run another one (two actually)wires (in effect)around the bulkhead to get by the problem of the great amt of current going thru the inadequate bulkhead connectors at those 2 points. If you have 2 unused connectors in the bulkhead just drill them out & run 2 wires thru there for the 2 parallel circuits. If not then drill 2 small holes in the firewall. www.madelectrical.com will have addt'l info for you. If I think of anything else I will holler.

Thanks, Robert. I did a search on Moparts, and did find some posts on the parallel bulkhead bypass. From what I can see, the M.A.D. way does away with the ammeter, and natcho's way keeps the ammeter in use. So, any idea which way is better? I was planning on using the stock gauges, which are in a rallye dash that came with the car, not installed. I have tested the gauges, and they all seem to function.

I'm old school I like the ammeter (& an added voltmeter) so I'm with Nacho's bulkhead bypass along with cleaning/checking EVERY connection (time consuming though) and since I never have a high flow (charging or discharging) I have no issues. At my age I dont even listen to the stock radio anymore . I'd rather listen to the eng (& my thoughts). If I had alot of draw inside the dash like you I'd run the batt positive over to the alt w an 8ga wire w a 12 ga fusible link which would alleviate the bulkhead shortcomings but would disable the ammeter

Thanks, Robert. I don't really like the notion of running the wire through the bulkhead, just for the reason that it would make it a pain to get the bulkhead connector apart if needed. The idea of running the wires through the firewall using a grommet seems much more workable, since unplugging the bulkhead then would not be a problem. I take it that natcho's way keeps the ammeter working? I was orginally going to use aftermarket gauges, but with a rallye dash, having only the fuel gauge working (well, and the speedometer, too) would seem such a waste. Since the sending units for the water temp and oil pressure are still available, I think I might go that route. I did consider an aftermarket dash (or maybe designing one myself), but that's in the future. Anyway, can anybody advise if the installation of the Painless fuse block would preclude me from doing this upgrade? Should I consult with natcho first? Thanks again!!!

OK, let me try to explain the situation. When I wired in the new fuse block, according to the instructions, the main feed wire, instead of routing it to the ammeter, it was routed to the fuse block. So, you are saying that I need to splice in the ammeter between the bulkhead and the fuse block? If so, that's not really a problem. However, what about the wiring upgrade where I run the 2 wires through the firewall? Can that still be done, and if so, how?
Thanks for your help, btw!!!
Oh yes, the Painless items are quality material, but there are so many different companies out there now that competition is tight! Even Summit is offering a universal harness now.

(1) yes (2)Yes, visualize the 1 parallel wire on the fusible link side coming around to the inside of the dash (backside of the bulkhead) where it T's back in, several inches rearward from that T splice is where you would cut the wire to add the ammeter leads (3) you're quite welcome on the help, my fellow (Moparts) members here save my bacon regularly.

the long vertical line is the firewall, (1) is the starter relay, (2) & (3) are the black bulkhead halves, (4) is Nacho's bypass. (5) runs up to the stock ammeter in the dash but to add a different ammeter you would cut the line and run the two cut ends (5) & (6) to your new ammeter (7), Downstream from the ammeter goes to a T just like OE then it splits off and powers the headlight switch (8)(which is hot all the time), another split to the ign sw (9) which is hot all the time and splits again to the fuse block (stock or Painless)(10)(which is hot all the time) which protects everything downstream from it such as brake lights hazard flashers, horn, radio, dome light, accessories

OK, I think I got it now. However, if your drawing is good, I wired the fuse block incorrectly. I did it according to the directions, though. But, I guess all I need to do is wire the ammeter between the bulkhead and the fuseblock to make the ammeter work?
Also, can you advise which wire powers the gauges? This is for a rallye dash, btw. The fuse block has a terminal for powering the gauges, and I am considering using it. I have looked for a rallye dash wiring diagram, but haven't found one as of yet.

We're still missing something easy as the ammeter would have to be before the fuse block and before the T and the T is before the fuse box because circuits such as the headlight switch ect which are hot all the time and are not fuse protected by the fuse box, current would be flowing (when they are on) but not thru the ammeter and I know that is not the case. I'm assuming you've checked out the wiring diagrams a www.mymopar.com. How is Painless wanting the ammeter to be placed in relation to their fuse box?

According to Painless, the way they advise the fuse block to be wired, it does away with the ammeter. At least, that is what the tech advised. And yes, I have checked with mymopar.com, and no rallye dash wiring diagram. I have located one, but it's for the Barracuda, which has a different rallye gauge setup.
Right now, I cannot locate any wire that powers the gauges. Getting sort of bleary eyed, so I am most likely missing much here.

Actually, this fuse block has provisions for the radio, horn, wipers, heater/AC, etc. I've already wired all those in. It also has provisions for turn signals, emergency flashers, an electric fan (if equipped), coil, ignition switch, light switch, stop switch, dome light, etc. All have been already wired in. I guess I'm only concerned about 2 things, how the gauges are powered, and how to wire in the stock ammeter.

the gauges would be switched on (hence the term switched 12V) from the ign sw and the ign sw is hot all the time so it would be fed from a T before the fuse block. Sounds like Painless is suggesting that you convert to a voltmeter rather than an OE or aftermarket ammeter. EDIT just saw your post. T into the ign switch (ign1) terminal. This is switched 12V and when you turn the key to "on" the gauges will be powered

that'd be in mymopars' diagrams unless that wire is different on a Ralley dash. I did my 65 dart from there wire by wire using spools & no mas and 65 darts are as bare bones as you can get

that and w the diagrams being split (& cutoff) I couldn't get it either (it'll take some more time) but I'm thinking black or dark blue w a tracer feeds the printed circuit round connector. We'll get it tomorrow EDIT I think the black wire is the 12V feed in

I came up w the little black wire is the 12V feed in on the circular dash plug in. I know the ammeter has to come before anything so that it will register any flow (in either direction). Post what they say.

Just spoke with a tech at Painless. They advise against using the stock ammeter, as it's 40 year old technology. I understand their reasoning, but I was hoping to have all my gauges functioning. They suggested the use of an aftermarket voltmeter. They also advised that there may be some company or individual that converts the ammeters to voltmeters. I'm sure this is expensive, but I would consider this if it wouldn't break the bank.
Anybody have any tips or suggestions?
Depends on your dash. MA did a recent article on converting a 71-74 B-body rally dash ammeter to voltmeter. I did the same with my dash with a voltmeter from a JY Isuzu Trooper (forgot what year). Looks factory. It's doable on the cheap.

Ok, avoiding the fuses and flasher deal itself what it looks you already did it here are my thoughs
as you can see on my diagram, the discontinued lines represents the Mopar wiring method
but then some doubts comes into my mind...
what source feeds the wire I outlined in pink to ign switch ? RED FROM STARTER OR BLACK FROM ALTERNATOR connected in to the fuse box ?
what about the LIGHT SWICTH SOURCE ? where comes from ? The POWER SYSTEM WIRE OR THE ALTERNATOR WIRE ON FUSE BOX ? instruction sheet on point 12 states: 12. ATTACH THE WIRE TO POWER UP THE HEAD LIGHT SWITCH TO THE LIGHT SW B+ TERMINAL. (RED W/ BLACK STRIPE WIRE) (12GA) but doesn't say whats the input source to feed it... power system or alternator wire
BOTH OF THOSE WIRES ARE spliced in to the alt wire on stock system to use ammeter correctly, but dunno what does feed the POWER SYSTEM WIRE into the painless fusebox.
when I know what feeds this wire into the new fuse box will be able to diagram how to wire it.
To be able to use correctly the ammeter all the load needs to be on black wire side of the ammeter
still analizing
( BTW, dunno why 2 acc wires coming from ign switch on diagram )
BASICALLY all my doubts are concerned into:
-on painless fusebox, What is the source what feeds the ign switch and the lights switch... Alt wire or Power system wire ?
-on painless fusebox, What is the source what feeds all the constant powered fuses/devices ? Alt wire or Power system wire ?
without having the fuse box in hands or without known the Chebby system ( what it looks Painless is based ), is hard to tell to me
Can you check for continuity to know what wires/circuits register continuity with ALT wire and wich ones with SYSTEM POWER wire ?

will work on it... patiente
fisrt... this is the Stock configuration on a Mopar ( tipical ). some models could it be slight diff, but mainly this is the setup. You can see all the consumption is on alt side ( but starter motor itself, not the relay what is activated from ign switch ), to make work the ammeter correctly

then we have this ( mainly ) from painless instruction sheet.
where, is clear what instruction says about the orange wire for acc on fusebox... but brown ?
then how is routed the red and black wires. Instruction says RED to hook to batt is the main system power... but black coming from alt ? what is for ?
then... lights red/white... I Guess is feeded from batt or alt.
then... we could break the red wire coming from starter solenoid and fit in the middle the ammeter wiring... but what is the black wire function ? are both linked together inside the fusebox ?
I guess the ign switch red wire is linked to... black or red ( batt or alt )
definitelly break the red line coming from bat and fit in the middle the ammeter will work to make work the ammeter correctly. But would wish to know about the rest.
Maybe I'm oversizing the "problem" BUT when I'm giving advices I like to get in to details and made everything correctly matched.

I also have a few more questions (as if you didn't have enough to think about, lol). Will the wires passing through the bulkhead be OK as long as I replace the wires and install new terminals with dielectric grease, or should I just run the wires straight through the firewall? Also, should I hook up the gauges to the terminal on the fuseblock that is designated for the gauges? It's a fused terminal.
Thanks so much, Nacho!!!
mmmm, I will run through firewall... no need to get rid off the original bulkhead ones. You can clean and replace terminals and will be definitelly fine, but also would run directy sources at a side of bulkhead.
Keeping the stock wires at bulkhead( once serviced ) will help on use a smaller gauge wire on parallel line. So won't need to use a 6 GAUGE WIRE LOL... just 10 or 12 will be nice to work together with the already existing 12 gauge one. If 10 better, and honestly enough. One 10 and the stock 12 will work more less like you have an 8 gauge wire.
You can in fact use terminals on parallel wires with 10 gauge wire to be able to service the wires or harness if needed for some reason. Automotive terminals are unexistant to 8 or 6 gauge wires( I haven't found at least ).
remember the first step is the parallel wires, but that will be just 40% of the job. The rest 60% is a good alt choice. No need for 100 amps alt really. Stock lates 78 amps is really enough, specially when using smaller pulley.
the reason to use a 100 amps or 120 amps alt or whatever more than that is just because you will get the best charge at iddle posible, but I bet won't use EVER the full alt capacity on your car. really on a basically stock car 78-80 amps alt is SIMPLY ENOUGH. EVEN if you get an ocasional discharge reading, nothing wrong with that.You'll find mostly of cars have a power decay with everything electrical working, just that they don't have an ammeter to take note about LOL and in mostly of these cases NOT EVEN A VOLTIMETER, just the idiot light what just say to you the alt is working because is not getting the circuit closed for a while stator is captioning magnetic field, but is not telling you is enough for your car or if batt is being discharged.
NOW THE QUESTION...
will the parallel wire running from alt post splice into the new fusebox black wire or directly to ammeter ?
THATS WHY I would need to know why this wire runs to painless fusebox.
Maybe just to get this line fuse protected, what woudl mean doesn't arrive to somekind of buss bar ?
if so, you can duplicate the black wire running to fuse box, but splicing directly to ammeter with an in line fuse, like the one it could be at fuse box ( if thats the reason of course )
this last is very important BECAUSE all the load will run directly to the fusebox, and will get a new weak point now there.
how many buss bars do you have on back of new fuse box ? which wires arrives ? If my logic dictates right, you should have just 2 buss bars, one getting orange wire from ign switch and the other one getting red from batt ?
then some individual fuses not linked to any buss bar, like the ign coil one, or maybe in fact the cluster lighting ? the alt exciter ( if you were using ), and stuff not labeled like needing acc or batt sources
lot of what I said is thinking outloud

One thing more...
with all this job, it looks you would ( if you still didn't do it ) get rid of the stock main splice, because it looks the new fuse box already works like a main splice, with the wires to feed lights, ign switch, alt, batt arriving to... and everything "fused"

Mopars used also very often a fuse to protect the gauges. Is a fuse what feeds the voltage limiter. Talking about 3rd gen chargers at least, we got the standart cluster gauges feeded from a fuse not linked on a buss bar, using a separated fuse what gets the source from the blue ( RUN position ) wire at ign switch, HOWEVER SAME YEARS, SAME CARS, but with rallye cluster got the gauges ( limiter ) source directly from ACC side of fuse box ( buss bar ), sharing some fuse with some other acc.
would need to check if some Mopar didn't use any fuse to gauges
you can run it or not as you wish. Definitelly won't hurt use the fuse to feed the limiter to gauges.
becarefull. DON'T RUN THE WIRE TO GAUGES DIRECTLY FROM FUSE BOX... needs to get first the limiter, then the gauges

Now I have some new questions. If you have a wiring diagram handy for a 1971 Valiant, the question is, which wire powers the headlight switch? I have a pink and a black with a white tracer that appear to both carry current to the switch. Also, which wire should I use to attach to the ignition coil terminal on the fuse block? Should it be the large brown wire, or the dark blue wire? I believe the brown wire is the bypass for the ballast resistor to the coil to start up the engine. Sorrt for all the questions, but my wiring of the fuseblock seems to have been a bit incorrect, and from hearing from you, it has been brough to my attention. I need to fix this before I install the wiring harness and fuse block, so all the help you can offer is greatly appreciated!!!

I don't really need the 71 diagram since all colors all years are the same in all bodies specially for those years.
yes, headlight switch gets two sources. One is unfused directly from alt splice ( as I "diagramed" )being black ( dunno remember if traced, but thick ) and one is fused coming from fuse batt side. Wire is pink.
The direct unfused black source feeds ONLY headlights beams. The pink wire feeds parking/sidemarkers/dimmer(cluster) and comes froma fuse on stock wiring. The original fuse also did feed the glovebox light and some acc constant sources like courtesy lights, map lights
Up to mids 70s Yes brown wire from ign switch bypasses the ballast on Start moment to max power on startup moment. Dark blue is what feeds the coil THROUGHT THE BALLAST on RUN moment, alt field, regulator AND CHOKE.
On lates 70s the ballast bypass was moved to starter relay and is closer to Painless wiring diagram
will draw some other diagrams about specifically those circuits paying attention on the 71 valiant diagram

ok... firts. as far I can tell and already stated, it looks the splice on alt wire will dissapear with the fusebox of course

then as far I can tell by the instructions, this will be the new setup at least for main starting and charging circuits
NOTE... I DON'T KNOW IF ALT WIRE AND IGN SWITCH WIRE ARE FUSED OR NOT, being simple spliced in to batt buss bar. I simply ilustrated like they are fused, but if they are the shgould be BIG CAPACITY FUSES... 40, 50 or 60 amps fuses.
remember this is just what I supose it is without have in hands the fusebox
I'm based on how it works any Mopar Body ( except those with starter solenoid with coil ballast bypass provision, on lates 70 )

next step... lighting circuit
As I can see, the painless fusebox only provides one fuse and circuit for all the lighting system, for a while Mopar uses 2 inputs and 3 outputs being the two inputs:
-Black wire ( traced white ? ), unfused, coming from alt wire ( as several diagrams did show ). Even is "unfused", remember the system is protected by the fuse link -Pink wire, fused coming from batt/alt source too
the three outputs: -green wire... headlights. Is ONLY FEEDED BY THE BLACK ( traced white ? ) WIRE -Black wire ( normally traced yellow )... parking lights and sidemarkers. Is feeded ONLY by the pink fused input -Orange wire... Dimmered source to cluster and stuff. Is feeded by the same PINK wire, and does have an EXTRA fuse on the line before get the bulbs
Now, to make it work in a Mopar way, this is my suggestion:
Splice the black ( traced white ? ) wire into the same MAIN SYSTEM POWER wire. You can also splice it in to the ammeter stud, black side.
Splice the pink wire ( was arriving to your original fusebox ) into the red traced white new fusebox wire
The tan wire to the dimmer function what becomes into the orange wires after the original fusebox can it be spliced together. System is already protected by the fuse existing to the red traced wire ( originally pink ), but you can also fit a separated fuse cap and splice in between the tan and orange wires. Tan and Orange wires were both arriving to the original fusebox to a separate fuse from both buss bars ( acc and batt )

please can you check what input source feeds the white wire to the "regulator" as instruction sheet states on point 8
ATTACH THE WIRE GOING TO THE IGNITION SWITCHED TERMINAL OF THE ALTERNATOR REGULATOR (INTERNAL OR EXTERNAL) TO THE ALT IGN B+ TERMINAL. (WHITE WIRE) THIS WIRE TURNS ON THE REGULATOR WHEN THE IGNITION SWITCH IS TURNED ON. (14GA)
ACC buss bar ? Coil wire ? some Ign swicth wire ?
Then also on Diagram is shown a red wire 18 gauge to feed the choke... same question... what source feeds that wire ? ACC buss bar ? some IGN switch wire ?
Remember the Painless diagram shows an extra ACCY WIRE brown 12 gauge

Ok this is what I see. -first the initial idea what I like more, for the starting-charging circuit: -then both circuits fused using the ALTERNATOR wire ( white wire ): what I don't like from the second diagram double fused option: -Engine will remain feeded when you set the ign switch power to ACC. why would you need to keep engine parts ( such as alt, reg, field, choke, ECU if existant ) powered IF YOU JUST WANT TO LISTEN THE RADIO ( for example ) -Everything will be feeded by just one point inside the ign switch, and one wire, black coming from ign switch. Then you can splice both blue and black wires to share the load, but honestly doesn't need for that -Why would you need to fuse the coil power at starting moment if it just work AT STARTING MOMENT ? rest of the time will just work the regular RUN circuit -In fact the original painless diagram shows this wire/fuse to run directly to ballast, so then to coil, making the ballast bypass from starter relay ( optional ). This setup was built on lates 70s Mopars. For a while bypass from the starter relay didn't exist, the ign switch was who made it. There are more options to use this white wire toward to engine parts, but will need to get inside the engine harness, modify it, use an extra cavity of bulkhead. Once again no need for that

My lights circuit suggestion remains the same ( more detailed diagram ) As stated before you can run and splice the black traced wire to feed headlights into the SYSTEM POWER WIRE or fit an eyelet terminal on it and attach it to the Ammeter stud. You choose. The original pink wire to lights switch is already around original fusebox of course. However check wich one, because there are couple more of pink wires around. Also, you can splice the orange cluster ( dimmed source ) wires with the tan wire coming from dimmer lights switch. Both wires are really close to splice them together since the original fusebox already had those wires linked with an extra fuse, separated from both existant buss bars. You can also install a fuse holder in between too keep the original setup, just that the fuse will be floating on harness a fuse holder like this: once again is your choice EXTRA NOTE ( not at diagram ): the cigar lighter is originally spliced at the same point/fuse where the pink wire takes the power and feeds input to parking lights. Is not ilustrated, but the red wire for the cigar lighter can still keep spliced to the same wire/fuse than the pink wire to parking lights input ( so the same red traced black wire at new fusebox )

Next... horn and wiper... pretty much straight up with some notes.
Locate the horn relay and will find the black and green/red wires. Black is ground to activate the relay. Green/red is the definitive positive output source to sound the horn. These are the two wires what will splice into the new fusebox ( points 2 and 19 at instruction sheet ). I guess the relay takes the power from the Batt buss and has a fuse too but I didn't draw the fuse to relay on diagram.
ONE NOTE ABOUT THE HORN RELAY...
The original relay is also a keys in buzzer warning signal. This relay drives two black wires, both coming from steering column. The black horn wire is grouped together with the horn functions and comes from turning switch harness plug. The buzzer black wire is a separated prong on relay and comes from ign switch harness plug ( becomes red into the column )
Next question. Do you want to keep working the ign key in buzzer function ? if so, then you will need to keep the original horn relay on harness to make it work still being feeded by the violet wire. Diagram shows this wire being feeded FROM THE ORIGINAL MAIN SPLICE AT ALT WIRE. Is this violet wire still being energized from there or somewhere ?
Then to note is you'll have two horn relays now, one just for the horn ( new ) and the original one just for the buzzer ( old ) are you agree keeping both relays ?
You can also forgett about the new relay at Fusebox and keep the original one. Once again your choice
----------------
Wiper pink wire shows on original diagram SPLICED SOMEWHERE INTO THE ACC WIRE COMING FROM IGN SWITCH. Locate this wire and now will splice into a fuse now at the new fusebox as isntruction sheet says, blue wire ( point 3 )

instrument cluster feed.
As the 71 valiant diagram shows from mymopar website, the cluster feed wasn't fuse protected either ( I stated earlier some models weren't fused there ) and were spliced directly from the RUN circuit at ign switch.
making this change the cluster gauges ( voltage limiter ) and warning lights will be fused protected.
NOTE: Making this change you won't have any gauge reading or idiot light ( oil, brake ) working for a while you are cranking. The original setup did keep work the dash instruments working when cranking since the ballast resistor was feeding back the cluster/blue wire from the Coil ( ballast bypass ) wire. Dimmered power since it was throught the ballast resistor but still working. Take that in mind.
wire is dark blue traced. There is another dark blue wire at a side arriving to cluster but is the gas sender one.

now, some stuff will need to work on at the same time. On Mostly of Mopars, and more specifically on your Valiant, all the dome, stop and hazzard circuits are protected by just ONE fuse. Why is that ? because is not normal you'll have everything working at the same time. In fact since 1970 is totally imposible to make work the brakes and the hazzards at the same time by the turning switch configuration.
The new painless fusebox provides you the chance to fuse them independently (sp?), but will need to pay attention on what are you doing.
first the discontinued line box shows how's wired the original setup, everything linked to one fuse coming from the batt buss.
The discontinued lines will show what lines WILL BE GONE by the end of the job, including the flasher, since the painless box gives you a flasher on circuit
will need to make a good track on these wires to make the correct splices.
as usual on all my diagrams, color are correctly matched with both setups.
Once again, I assume the hazzard flasher is fuse protected from batt buss bar, just that I didn't draw the fuse for it on diagram

LAST SECTION, what still rst of the acc section:
-turning signal -Radio -Heater/AC
Heater is pretty much straight up and even color matches. That wiring was already arriving to fuse box. Is a cut and splice on new fusebox job
Radio. Allmost the same. Instruction sheet doesn't say the wire color for this RADIO B+ so I draw same original color being spliced. Same as above you'll find is a cut from original fuse and splice on the new one. Will need to consider this circuit also feeds the BACK UP LAMP at bulkhead, being spliced from Radio Plug itself, and will remain in that way
Turning flasher doesn't have its own fuse, Shares same fuse than Radio/Back up lamp, so is spliced on same circuit, but from bulkhead ( W cavity ). This splice can it be removed together with flasher itself, and now the red wire going to turning switch from the turning flasher will be spliced into the purple wire at new fusebox. As stated on instruction wheet this wire already have the flasher on circuit ( I guess also fused ).
I think this covers all the circuits. If some more doubt, will be happy to clear up!

you should get not using from painless fusebox the ELECT FAN wire and the ALTERNATOR/REGULATOR wire since those functions are unexistant on the stock setup. You can use them on any extra function you wish to give power from ACC section.
REMEMBER I DIDN'T DRAW THE STOCK CIGAR LIGHTER source. It can be spliced at ant batt fuse you want, If you want to keep the stock setup, it should be spliced together with the pink wire of the lights switch ( arriving to red traced black at new fusebox )
Parallel wires from alt and batt simply will arrive directly to ammeter studs, Nothing to do with the new fusebox

Do you mean keeping the ballast wires and circuits ( blue and brown, RUN and START ) like stock without fuse ?
Yes you can do it, is not a bad idea... never though on that because I was making the setup with the Painless fusebox option to "coil"
how many amps ? 5 max. Original fuse for dimmer source is 5 as far I remember on my Charger. It should be casted on your original fusebox and stated on car's owners manual. Maybe A bodies are smaller due they use to use less bulbs to dash.
Remember if you still wire the dash instrument like the point #11, gauges ( and warning lights ) will still turned off when cranking. It is originally wired in to the RUN ( blue ) circuit, and now is being souced by ACC by painless, what doens't get the feedback power spliced from cranking circuit at ballast

Initially I like your idea... and maybe in fact myself will make it on that way.
however ONCE I got a short from blue line ( I didn't know about my car electric on those days yet ), when the alt brush isolator got broken and all the blue line began to heat up to ign switch, melting slightly a couple of plugs, so thinking on that, is not a bad idea get it fuse protected like painless sugestion.
The fuse for the dimmer line.... mmmm I don't think is EXCESIVELLY necesary and splice tan and orange together will work. Is already protected by the pink input line. Just that if some short at dimmer circuit, will blow at the same time with parking lights. A smaller fuse on dimmer circuit will blow the dimmer fuse first keeping safe the parking circuit.
Now... what circuit is more important to keep it fused ? which one is easier to get a short ?... make your choice
I think on this, is about a personal preference for each one

I GOT AN IDEA!!!
Do you find some way to separate the ELC FAN or the ALT/REG fuses from the Acc buss bars ? cut/separate the bar from fuses at those points ? AND still able to attach the tan wire on the cut/separated point from the Acc bar ?
you could use one of those fuses to feed some separated option from buss bars.
DASH INSTRUMENT source... you can splice the blue wire to cluster master plug into the pink wire going to ballast to keep it working when cranking as originally did
you can try also separate this DASH INSTRUMENT fuse from the acc buss bar and feed it from the blue line before the fuse box to make it work also when cranking, like originally is.
How are the fuses attached to buss bars ? can you give me a close up pic of that ? I can't detail that on pics you sent me

first... which red wire ? the main system power from painless ? that wire doesn't run to the bulkhead, will run to the ammeter ( black side ) to keep it working. after clearing that... MMMMMM Reeally really, no need for the stock 12 gauge replacement if you already will run the parallel wires. IMHO keep that one on the way it is, and run the parallel ones on 10 gauge. If you want to be able to keep "serviceable" all the circuit including the new ones through the firewall, the new parallel wires can be plugged with the bullet kind ones on engine bay side. They are available for 10 gauge, the ones with yellow covers ( I think those are what supports 10 gauge ). Since I don't like the colored look of those plastic covers I normally cover them up with black ( or wire matched color )shrinking tube NOTE... even terminals can it be simply crimped, I normally also SOLD THEM. That gives you better power transference and harder to loose from terminal. In fact as far is posible, SOLD EVERY SPLICE... don't simply twist them together you can tin the ends before twist them but you can tin them after being twisted too with the propper heat range solder, specially big gauge ones. Small gauge wires can be tined either way after or before. wrong way: maybe you already did know this, but never is wrong to give more info just in case

Yes, that was the red wire I was speaking of. So, if I run the parellel wires, do they get attached to the ammeter? If so, how? And, which gauge of fusible link do I need to connect to the starter relay for the parellel wires?
Also, as it is currently set up, the red wire does run from the bulkhead to the fuse block. I don't have the dash installed yet, so it's not attached to the ammeter. Right now the red wire comes from the bulkhead connector and feeds the fuse block.

Ok here is the diagram with the parallel wires on it and the main circuits ( I simply edited the one I already had made )
as you can see I'm posting wich wires will still run throught the bulkhead plug. Honestly no need to eliminate them, but some service on them will be nice ( clean, new terminals if wished, dielectric grease )
the parallel wires will still run up to ammeter studs... why? because when you run the parallel wires, the black wire from ammeter to fuse box won't necesarilly feeds the power from batt, through ammeter, now will feed the power from alternator too ( as far alternator is enough of course ) because so that will DOUBLE the direct and original wire coming from alt through bulkhead.
So we can say ORIGINAL we had one wire ( labeled A ) what it was the only one feeding the main splice originally, now directly the fuse box bar.
The added B wire through the firewall, attached to ammeter, will make we are getting two wires now LABELED AS C to feed the fusebox buss bar from alt . Once again as far alt is enough. If alt is not enough, then batt will feed through ammeter. Ammeter will tell you when that happens, thats its function.
8 or 10 gauge... 10 is really enough if you ask me and will find terminals for it at hardware stores. I fit 8 gauge just because it was one one I had handly from a Coronet 77, but that made me imposible to find a terminal to fit on engine bay side to be able to service that because there is not 8 gauge terminals.
Batt side parallel wire I used a 10 gauge and fit a terminal to attach to a new fuse link. ( 14 or 16 gauge ). The original fuse link it is 16 gauge. Mopar wirings showing parallel wires shows 14 gauge for that parallel fuse link, but 16 will work too without problems. At the end yoiu are also doubling the fuse link, and use a 14 gauge will take too much time to blow in a short problem.
why use a 10 gauge wires if still stock wires betwen ammeter and fuse box and alt and fuse box are 12 ? because teh extra gauge step is for BATT CHARGING moment, safer, not really because the regular car equippment requires MOOORE thicker wires. You are not driving a Motorhome, is a regular passenger car.
Will you use an UZI to hunt rabbits ? everything on the right and enough measure. No need to oversize stuff

remember the fuse box is on painless box becoming on the original MAIN SPLICE.
The MAIN SPLICE needs to keep on alt side of ammeter to keep the right reading
the instruction sheet on painless box says attachs the batt wire on the red 12 gauge fusebox wire just because they are not thinking on an ammeter on the line
So keeping the original wiring, the batt wire will still keep running directly to ammeter.
THEN FROM AMMETER ( black wire ) to the painless fuse box 12 red wire. ( main power source )
The ammeter is simply an IN LINE DEVICE coming from batt, what reads the batt power status.
Imagine the ammeter doesn exist... well you are making the same than instruction sheet says, you are feeding the fuse box from batt... but on this case with an ammeter in the line ( serial conection ).
remember BE SURE hook the right wires at ammeter. The BATT ones at the stud labelled RED on back of cluster, and the black wire at the normally unlabeled stud.
If you hook reversed, won't happen anything more than simply a reversed reading on ammeter
extra note:
remember on stock setup the black traced white wire to headlights switch wire is spliced at the main splice ( alt side ). You can splice it at the main system source ( painless red 12 gauge wire ) or directly to the black stud at ammeter. Will be easier to you hook it with eyelet terminal directly to the ammeter black side stud and will give you a less stressed wire on that section ( section between ammeter and painless fuse box )
If you hook the headlighst wire to the ammeter studs will have 2 wires on red ( original and parallel ) and will have 3 to the black side ( original now running to painless box, parallel and headlights wires )
BE SURE CLEAN the terminals arriving to ammeter AND TIGHT the ammeter nuts to be sure about a good power transfer. Lot of problems use to begin there.
Dunno what you decided to do with the horn relays, using the original or the one with painless box... and still keep the ign key in buzzer. If you decided to keep the original full relay function or if just use the buzzer function of it, the Violet wire of the original relay it must be constantly feeded. As the valiant diagram shows, normally is spliced at the MAIN original splice, so you could run that wire also to ammeter black stud, to the MAIN SYSTEM red wire at painles wire splice or also to any BATT source at fuse box after the fuses.
dunno what else to refresh right now
Dunno what you decided to do with the DASH INSTRUMENT source, from acc side of box

Right now I have the headlight wire attached to the terminal for power to the headlight switch (#12 on instructions). As for the instrument feed, I haven't changed that yet, but was going to. That terminal is fed by a 10 amp fuse. Should I change that, or leave it as is? The horn relay, I used the Painless one, but would very much like to keep the buzzer. So, I need to keep the violet wire hot? Also, what about the black wire from the instrument panel? From the 1970 Plymouth Valiant wiring diagram, this wire feeds the electricity to the printed circuit connector, which (I believe) feeds the voltage regulator for the instruments. On the rallye cluster, the voltage regulator is built into the fuel gauge. Does this wire need to be attached to the fuse block at the dash B+ terminal (#11 on the instructions)? I know, lots of work on your part. But, I don't think I could make this work without your assistance, so I hope you don't mind all these questions!!!

no I don't mind all the questions. thats why we are around and boards intention. headlight wires... Remember Mopars have two diff sources for headlight switch ( pink and black traced white ). Painless is Chebby based so thats teh reason they give just one source for it. I guess if you hook the black traced white wire in to the point 12 at instructions, you spliced the pink wire there too, right ? If you ask me I would preffer to keep the original setup with two diff input sources. Just my personal preference. If your fuse blows out because some fail on parking lights feeded by the pink wire, will be out of headlights too because the black traced white is spliced there too. Dash instrument fuse... 10 amps, is not bad but maybe I will feed with 8 amps. Black wire for instrument panel ? Valiant diagram shows a blue one not a black one. Dunno if standart or rallye makes diff on wire color alos for A bodies. It does on B bodies, but dunno on A bodies. Is a fact the DASH WIRE on painless fusebox must arrive to the voltage limiter because voltage limiter is the source for the gauges. But Painless DASH WIRE must feed also the idiot lights ( normally blue wire on stock ), but not through the voltage limiter. Idiot lights must be directly feeded from the positive source. On B bodies with rallye cluster, gauges are feeded with a black wire from ACC directly to the voltage limiter for a while Brake light is a blue wire directly from RUN. On Standart Cluster all dash ( gauges AND idiot lights ) is feeded by the blue wire from RUN circuit with voltage limiter instered in to the blue wire circuit at printed board. Maybe A bodies are the same ? I guess because Mymopar website doesn't show any rallye diagram Buzzer. yes, will need to keep the violet wire hot.

About the light switch, yes I did splice both the pick and the black w/white tracer together and attached them at the light switch terminal. I didn't know where else to draw any electricity from for both wires individually. On my rallye dash, the blue wire feeds the brake light, and the black wire feeds power to the voltage limiter. The gauge layout may be different from a B-body to an A-body, I don't know for sure. I can say that an early Barracuda rallye dash layout is different from mine. I also could not locate a rallye dash wiring diagram, and have posted on here as well as mymopars, but with no luck so far. I do have a copy of the printed circuit boards for the Duster/Valiant (and others too), which has helped a lot. Do you need me to give you a rundown of the terminals and what I have connected to each one, maybe for one last check before we finally finish this?

yeah well your rallye wiring is the same than my rallye wiring... yes the black wire to voltage limiter will be spliced in to the DASH INST wire of painless box.
Blue wire for brake light. To make it CORRECTLY into a Mopar way, must be spliced into the blue RUN circuit. Now, mostly sure you never touched that though. That will set correctly that when you crank the engine, the brake light will remaing lighted up ( but dimmed )
On a standart cluster as stated, is being set diff just by one wire to feed everything ( blue ) and to set correctly the painless box in a Mopar would need to modify some stuff more. I based my suggestion about the dash feed mods ( cut the buss bar or whatever related ) on the Standart cluster diagram. No need it on this case now.
to draw both lights wires, splice the black traced into the ammeter black wire stud OR the MAIN SYSTEM SOURCE. as you wish. I think easier directly to amm stud. Keep the pink into the fuse box provision. Well thats my suggestion to make it on the Mopar way. Both spliced into the Fusebox provision will work too though but when the fuse blows, you will be OUT OF LIGHTS EVERYWHERE. It happened to mee that I blowed that fuse simply replacing the glove box bulb ( didn't unplugged batt ) because on my car, this bulb comes from same source. Dunno remmeber on your car. Will have to check. I could get without headlights just for that if they were on same source.
a rundown will be nice.

OK, here it is: Battery feed side, from left to right: Horn terminal - green w/red tracer Ign sw coil - dark blue w/white tracer from ballast Batt feed - empty Ign sw B+ - red wire from ignition switch Stop sw B+ - pink wire to brake switch Alt batt post - black wire from alternator Haz sw B+ - pink wire to directional signal plug Light sw B+ - black w/white tracer and pink, both to headlight switch plug Dash B+ - black wire to voltage limiter in cluster plug Radio B+ - to radio plug Acc side, from left to right: Horn sw - black w/white tracer to directional switch plug Wiper B+ - to wiper plug Coil/Dist - dark blue w/white tracer out to ballast Dome light B+ - to plug for rear harness El fan B+ - empty AC/Heat - black w/white tracer out to fan controls Alt ign B+ - empty Ign sw accy - black from ignition switch plug Turn sw B+ - red w/white tracer o directional switch plug I'm sure I have some of these incorrect, so please advise your opinion so I can make the proper changes. I think that I may have the ballast wires incorrect, and I will also change the power to the light switch as you had previously suggested. Thanks!!!

Caps, my notes: Quote:
Battery feed side, from left to right:
Horn terminal - green w/red tracer---- YES, RUNNING TO BULKHEAD
Ign sw coil - dark blue w/white tracer from ballast---- WELL I GUESS IS REALLY THE ONE COMING FROM IGN SWITCH
Batt feed - empty ---- THE ONE ( BLACK )COMING FROM AMMETER
Ign sw B+ - red wire from ignition switch--- YES
Stop sw B+ - pink wire to brake switch--- YES
Alt batt post - black wire from alternator--- YES
Haz sw B+ - pink wire to directional signal plug--- YES
Light sw B+ - black w/white tracer and pink, both to headlight switch plug--- YES SOMEHOW. MY PREFFERENCE IS SPLICE THE BLACK ONE ON A DIFF POSITIVE SOURCE BETWEEN AMMETER AND FUSEBOX MAIN SOURCE. JUST MY PREFFERENCE LIKE MOPAR DID. BUT WILL WORK.
Dash B+ - black wire to voltage limiter in cluster plug--- YES
Radio B+ - to radio plug--- YES.
Acc side, from left to right: Horn sw - black w/white tracer to directional switch plug--- I CAN'T RECALL BEING TRACED, BUT YES, BLACK COMING FROM DIRECTIONAL SWITCH
Wiper B+ - to wiper plug--- YES, PINK ONE
Coil/Dist - dark blue w/white tracer out to ballast--- YES
Dome light B+ - to plug for rear harness--- YES, PINK ONE
El fan B+ - empty--- I GUESS LOL
AC/Heat - black w/white tracer out to fan controls--- YES. I GUESS YOU HAVE HEATER, NON AC
Alt ign B+ - empty--- YES
Ign sw accy - black from ignition switch plug--- YES
Turn sw B+ - red w/white tracer to directional switch plug--- I CAN'T REMEMBER TRACED IT, BUT YES
I'm sure I have some of these incorrect, so please advise your opinion so I can make the proper changes. I think that I may have the ballast wires incorrect, and I will also change the power to the light switch as you had previously suggested.
Thanks!!!
I thought you where to use the coil fuse for the dimmered cluster source instead ( tan and orange )... whatever, you set it right for the original use. If you decide to use for dimmer, will be fine too.
then beside everything of this remmeber after make some cuts you could it be cutting some power sources like cigar lighter, glove box... These must be sourced on any constant power source at batt side. You can have also some BATT source around hanging around on underdash harness. This source is a rubber plug with 3 female bullet terminals color red. You can splice these into the hazzards or brake fuses section. Normally in fact the glove box is plugged into the BATT rubber plug I was talking about hanging around.
Key In Buzzer... violet wire also allways hot. It Can be fused or not. Like the cigar lighter or glove box lights, OR like originally factory did, between ammeter and MAIN POWER SOURCE
I guess the blue wire to brake light is still attached to the RUN circuit. If you did cut it, you can splice it after the fuse to coil. That will tell you if fuse did blow or not.
I guess you rid off both flashers around and related wires.
BE SURE THE BATT, AMMETER, ALT AND IGN SPLICES ARE GOOD MADE!!! These runs ALL the car load

OK, as it is right now I have the red 12 gauge wire that comes from the starter relay straight to the fuse block from the bulkhead connector,connected to the batt feed terminal. Can I just cut that wire and splice in the ammeter? I also will run the parallel wires to the ammeter.
You are correct, it is a heater only car, no AC.
I will attach the power wire for the headlights (black w/white tracer) to the black side of the ammeter, as you suggested.
The dimmer for the lights, I will connect the tan and the 2 orange wires together, and splice in a fuse. I would rather use the fuse for the coil, as directed in the instructions.

on the way you did, you were bypassing the ammeter
to keep working ammeter, it must be in the middle of the line of the starter relay wire ( batt ) and the MAIN POWER SYSTEM wire at fusebox
be sure all the eyelet terminals to ammeter good crimped AND welded. I would cover this crimping/weldin section at terminal also with shrinking tube. Two of them to extra isolation
of course, nuts propperly tightem up.

if you don't care to run wires allong all the engine bay, I you can go directly to radiator core support ground point... or even in fact directly to batt post.
However that is too much wire going through engine bay without need for that. You can try also a stud, or bolt with a nut from inside the cab somewhere at firewall on a clean of paint spot and also run up to there the engine ground strap.
You can weld the bolt to from inside the cab too, going through the firewall.
Another posible good spot and won't need anykind of job are the wiper motor studs!!! but thats MAYBE some far away from block to attach the engine ground strap, I mean if you take the idea to use the same spot for it. It is at least a little bit far away on B bodies. Maybe not too long distance on A bodies. You can also get a longer ground strap too to get it.
just some ideas comes into my mind right now.

maybe yes... dunno. Never searched for it. Maybe radio Shack up there ? ( we don't have radio Shack down here... used to be here but not anymore )
Maybe in fact some car parts shop like Advance, Kragen...
But honestly I don't think necesary a buss bar. Engine bay devices only requires ground for ECU and Regulator and both can it be tighten up with same ground strap. Lights have the ground on radiator core support. Parking lights by chassis itself same as wiper motor. Horn is body ground too, and no one of them are critical like regulator and ECU.
but you have the option to make it as your wish
