Sounds like it was super ghetto rigged.... Imo might be easier to give to a shop that can put a junkyard harness on and fix all the issues. Too much headache for you

I saw the same issue with a 2000 silverado with an aftermarket alarm system...that thing was wired horribly. A mechanic was able to fix the wiring issues, but i would be it is because of some bad wiring, specifically a non-grounded/exposed wire (that was the issue on this truck)
