All my electrical woes.
When wiring gets chopped up like this, it's REALLY difficult to troubleshoot "by remote control." I'd say you need to work on a local guy who knows wiring.
Decide if you want to rewire it as per stock, or aftermarket, like some of the wiring kits spoke of around here. I think it's Abodyjoe likes "American auto wire" or similar. Contact him--he's got some documentation online for that
I don't really like Painless and Francis kits --they both kinda ignore us Mopar guys. I bought a "used sorta as new" Painless kit off Craigslist, and basically just used the fusebox and part of the attached wiring.
Do you have a shop manual? You can download them on this site.
"MyMopar" has some wiring diagrams, but they leave out the seat belt interlock system, and some of the accessories you might have.
