What Harness and any tips??

One thing, some of the cheaper universal harnesses may be designed more for "hot rods" such as roadsters, etc. Be sure the tail harness is actually long enough.

Several of these harness makers annoy me for several reasons

1....Some the wiring is printed, which is fine until you wish to "repurpose" it. For example, if the wiring is marked "power windows" and you don't HAVE those, but maybe want to use that circuit for something else..........................

2...The fuse panel setup / distribution is weird. I've forgotten specifics, but seems to me on mine, originally, some things came on with accessory or igntion that should have maybe been preferred the other way around. I actually took the fuse panel apart and changed a few things

3...Documentation leaves a bit to be desired. An actual diagram is sometimes better

4....Several of these manufacturers completely miss "Mopars." The little tricks such as the setup of starter relay, of the concept of IGN1 and IGN2, and so on. Mopar, and some AMC, are about the only brand which has a grounding switch for neutral safety.
