Does anyone have any input on swaping a 1973 Ralley Dash for the origanal 1971 Ralley Dash. I have the complete wiring harness with it. Would it be plug and play type swap or is there more to it that I an not considering. Thanks for any help.

Not sure about 73 but i swapped a 74 harness into a 71 to replace a melted nightmare and a lot of the connectors were different.Had to swap connectors to match up to the 71 switches and heater controls.Also had some extra relays and other stuff that my 71 did not have.Both cars were factory rally dash with ac.Might want to compare the wiring harness first.Could just swap the cluster without any problems i think.

differences between 71s and 73s on harness are:

-wiper plug... one piece on 73 instead 2 pieces on 71s. 71 wiper switches are in fact also bigger. Wires are the same though.

-seatbelt deal... 73s have sensors on seats and retractors, giving that signal to 73 harness, where will find a Relay what controls the buzzer and light signal getting the seats/retractos siganl and tranny gear signal to turn on the warning light and buzzer. On 71s this light is flasher timer controled ( same flasher than the ign key courtesy light ).

-also the seatbelt light is switched by ground since 72 for a while on 71 is switched by positive

-Some wires turned around between headlight and engine harnesses ( horn, windshield washer, prop brake ) need to be checked and matched

-As stated, AC/heater control but mainly because the kind of plugs, specially the blower one, but same as the wiper, wires are the same.

NOW... CLUSTERS ARE THE SAME BY THEMSELF. Maybe some differences it could be 120 or 150 miles speedo, blue or red pilot light for higbeams... if you are simply switching clusters for whatever reason, you will need just to take care about the wiper switch, mounting your old one on the new replacement cluster. To keep your 71 setup, keep also the 71 AC/Heater control unit. Keep your 71 underdash harness. Change to 73 harness and make it CORRECTLY will need some more details to match.

The woodgrain bezels are different because the latter dashes (73-4) had the wiper / lights indicators that the earlier dashes did not, so it will not look "correct" for a 71 Bee.

Hey Nacho, I've never seen a 71 with the seatbelt warning light. Have you?

yes, locally and also in USA( web pics )... in fact some of them were with the convenience driver package ( low fuel light ) when optioned

they are on diagrams too.

here is the diagram with the Driver convenience package

( on cars without the low fuel light but still the seatbelt light the black wire to ground runs to the plug with two terminals in place of the labeled blue wire )

a little off topic, but if switching from the standard rally dash to the rally dash with the tach, is the harness different? if so, how much different? both have the 150 speedos.

If you check around on ebay, someone sells the little add-on harness you need to hook up the tach. It's the same guy that sells reproduction tachs for these cars.

There is a big difference between the rallye harness and the standard harness. The standard harness plugs into the dash with a large round plug. the rallye are split into multiple feeds.

there are 4 Ralley dashs
1 71-73 standard Ralley dash can not put in a clock or tack standard
2 71-73 Ralley dash that come with clock or tack
3 74 standard Ralley dash can not put in a clock or tack
4 74 Ralley dash that come with clock or tac

It is impossible to install a factory tach in a cluster that did not originally have a tach or clock. The pod for the tach or clock has an opening in it with a screw on cover to allow the installation of the tach or clock. The non-tach/clock clusters do not have this feature.
Basic definition is rallye dashes had round gauges while the non-rallye did not.

ya I know that, I have both with and without the tachs. Im just looking to see if the harnesses were close enough to be interchanged, but im guessing not. thanks

74 custer is the same the earliers, just the face changed due the icons. If you fit a 73 Bezel on a "74" cluster will get a 73 without diff with original 73s

then also on 73s Speedo changed to 120 miles and blue/horizontal high beams pilot light.

But those stuff are parts of the cluster, not the cluster itself.

The DOOR LOCKS signal on the picture... I think those were sedans, not 2 doors, but not sure about though. As far I know you could get also JUST the seatbelt light too. At least locally they got ( not everyone ).

Tach harness is an ADD ON harness to the underdash harness. You don't need to modify anything to fit a tach harness to the underdash harness, just locate the terminals and plugs on the right locations. Same about clock where unique wire required is a small black wire hooked to the amm stud.

You can modify a non clock/tach housing cluster to fit a clock/tach. Locations are on casting, but requires job to modify, and get teh complete meters setup

I thought the tach wiring was already in the rallye harness. It was the wiring from the bulkhead to the coil that was an addition.

the feed is from a gray wire to the #20 bulkhead and a separate wire for the lighting which is usually orange.

I attached the 71 wiring from the FSM.

The pic on the top is a standard ralley gauges. Notice that the big round one has fuel, and temp gauge and the 2 small ones has alt and oil and they're blank underneath. So if you cut the hole for a tach, how are you going to hook-up the fuel and temp gauge

look at pic 2 the small ones have oil alt fuel temp

As Nacho mentioned above, it can be done, but you still need the gauge faces (the black plastic part that covers the needle attach point and mechanical workings). The gauge backing plates (the metal part behind the needle itself) would need to be painted and decaled.

I havent looked at the internals, but my guess is that the internal gauge workings are similar, so that they can be reloated to the appropriate new locations on the cluster frame, (reverse wire one for proper movement).

Probably be easier to find someone parting out a clock/tach cluster to get what you need. I sold a clock/tach cluster frame with two good gauges on it last year on eBay for $15. (No bezel and bad plastic.) So the stuff is out there.

yes definitelly is easier get the cluster because if you want to modify a basic rallye cluster to convert in to a tach cluster, you'll need to find a parted out cluster parts ( lettering bezel and gauges ) what is harder. But it is definitelly doable.

If you look at back of cluster housing, you'll find the casts marks for the clock/tach gauges setup, ( studs and everything )

wiring locations ( + and - ) won't change anything on reading. You can reverse polarity and gauges will work the same
