Using large welding cable which by its nature its insulation is thick/heavy duty. Batt neg post to good ground in trunk (down to subframe recommended). Batt positive post directly up front under the carpet to the starter big "batt" lug (no trunk solenoid). A lead from the starter batt lug to the starter relay and from the starter relay to the alt. Power everything up front (switched power) from the batt lug on the starter relay to the ign sw just like normal. Back in the trunk put the on/off switch in either the positive or the neg cable. Use appropriate fuses/circuit breakers as desired (I do not). IF a person uses a trunk solenoid & it is going to be energized all the time get a "continuous duty" unit rather than a common parts house furd solenoid & it'd probably be a good idea to use a continious duty one either way just for longevity. (trunk solenoid aside) Just me, this keeps it simple with the only change being that the batt is now sitting in the trunk rather than sitting up front & there's the longer cable needed to reach it. I dont sweat having the cable under the carpet hot all the time (welding cable insulation is thick) & I do keep it away from any sharp edges that could fray it over time & that is a good use for black electrical tape. EDIT if keeping the ammeter, put the ammeter in series between the starter big "batt" lug and the big "batt" stud on the starter relay that's on the fender/firewall. MORE EDIT If not using a trunk solenoid run a lead (like OE) from the "st" terminal on the ign sw out to the "ign" terminal on the starter relay & a lead from the "sol" terminal on the starter relay down to the small terminal on the starter/solenoid

You are making this more difficult than it needs to be.
Why a CD relay on the starter line. Wrong piece and totally unnecessary. Use a Ford relay, cheap and easy. Fuses and Breakers... ?????
You need to be aware of the amp load flowing through each device. Those 4 poles are not a great choice in some cases.
Use the appropriate device for the task.
You've seen a couple of methods to wire things up and got some confusing responses from a person on another board. That person knows what he's talking about most of the time. In this case he's way off base IMO. You've added items to them that are not really necessary. Keep it SIMPLE but safe. Just remember, there is a minimum standard and improvements on that minimum standard. ------------------------------------------- Do you want a fat starter wire running forward being hot all the time? Yes, just run that fat wire forward direct off the battery. No, place a ford solenoid in line.
Want the alt line hot all the time? Wire it staright to the battery. No, place a CD relay in line.
Those are the two biggest issues IMO. Pick where you want the system
to be totally dead in the car when the master is turned off.
thanks RobX4406, yes i think this past week reading and looking at diagrams has made me more confused than when i started. So put in a ford solenoid in line for the starter and a cd relay for the alternator and call it good?
im just trying to be really careful/safe as i've been working on this car for a long time and dont want something stupid to happen because i went cheap/unsafe.

Thanks for the replies, but if i want to take it to the track dont i have to be able to kill the engine with the switch? How would you wire it?
The simple way is to use a simple 2 post switch at the trrunk. Run the charge wire from the alternator to the trunk (6 gauge min) and put it on battery side of the switch. No relay required.
When you turn the switch off, power from both the battery and alternator is shut off completely.

Glad to see this topic posted. I will soon be relocating my battery to the trunk on my '70 Challenger, and have done some internet research in the recent past, but find it all a bit confusing. I am not very good when it comes to vehicle electronics/wiring. So hopefully this thread will give me some help and better understanding. I certainly don't want/need a complicated scheme; just one that is effective, simple and safe. Already planned on using "0" gauge welding cable for main positive/negative leads. Probably will be doing all the lug and terminal installations myself.
If you use welding cable get the EPDM insulation.
That's a much better choice for sizing over the normal 2 gauge stuff most kits come with.

At NAPA in the Belden line are cable ends that are compression type, no crimping required. I believe they are intended for commercial trucks using heavy cables.

CD relay is a continuous duty relay. S605 relay works. Cole Hersee has spst CD relay in varying ratings. Make sure it's sized properly. http://www.colehersee.com/home/grid/cat/169/See the diagram linked above, not the first post, down a few. On a street car, instead of triggering the CD relay using the cut off switch downstream side, use a keyed source. That way the CD relay only active when the car is running or key on.
