provided the guy with the harness for sale didn't buy one of the overpriced harnesses like a yearone that i think runs up to about 1k then i say go ahead and buy it if it doesn't create a money issue for you. Maybe you can get it for 200.00? I think that would be a deal. I installed the ron francis xp68. Connectors are gm but there's really only a couple of places that comes into play most notably the steering column and you need to keep your connectors for wipers. I decided to go ahead and replace everything with new in an effort to eliminate future issues with old wiring and connections. Knock on wood i will not have any electrical issues for a long time. I had never rewired a car before and had it finished after a a weekend of long hours followed by a week working on it for a couple hours a day. IMHO connectors alone in a few places does not justify paying upwards of 500.00 more for another harness. I think ron francis has added more mopar specific harnesses, but almost all these aftermarkets are going to have some gm components (headlight switch) and connector. It's not IF you will have electrical issues it's WHEN. I also deleted the bulkhead connections...put a plate over the hole and passed through a grommet. updating the wiring was my first priority since i will keep my vehicle for many years for my kids.
