Need help for a 74 duster wiring harness **pics

BTW, the hole in the firewall for the bulkhead connector wasn’t even the same as the earlier years. So I don’t think you could even swap both the engine and dash harness from an earlier car and make it work.

I don’t know, maybe some of the earlier engine harness would plug in and work? But I am certain the dash side of the plug will have to be ‘76 to fit the hole in the firewall.
