Rallye Dash Harness

[Cudapile]

What years will a 72 Rallye Challenger dash harness work on, I’m assuming it would be the same for Cuda’s also.
Thanks

While essentially the same for all years this is not an easy question to answer .
The positions of some of the wires changed in the bulkhead connector & there were different wiper switches & of course the seatbelt warning light in 73-74.
the wires can be relocated in the bulkhead easily & the harness can be adapted for any year .

Good information, thanks.
What’s a good resource for bulkhead diagrams for 70 to 72.

Of course as long as it has not been cut, wrapping has come loose, insulation is not still soft and supple, connectors not brittle/broken/missing/corroded. It is better to replace 50 year old wiring.
The biggest problem with 60-70's Mopars is wiring. Mainly shorts and ground problems.
Wiring is the literal arteries and veins of your car. They carry the proper amount of current to all the electrical components and must be sufficiently grounded.
They are not cheap, but they are never given any maintenance either. They just quietly do their jobs.
