I've put several Painless universal harnesses in old Mopars. Other than the wire color, they looked stock and work awesome. You can get the terminals for the factory bulkhead connector and all the hardshell connectors mopar used. New bulkhead connectors are also available. The places that make the re-pop harnesses will sell them separate.

As for the quality, I used the EZ wiring harness on an old 52 chevy truck I did. The guy drives it 2-3000 miles a year and hasn't had any probs. Quality of the product seemed ok.
