I would re-run all your wiring because it sounds like someone did a half-*** job when they wanted to pull a trailer. Just follow the leads that are already there and just splice and solder new connections.

As for running the new trailer brake and power leads, those are the easy ones!

 

I've completely removed the trailer brake stuff and replaced the wiring going from the the taillight splicing. I've also replaced the quick splices. I've tried hooking up to 3 diff trailers with no results. All fuses are good. I don't see any shorts. Wtf?! Thanks for all the help Old_School! I really appreciate it. I've sent you a new message as well as on here.
