We went wheeling the other day and I noticed my running lights were not working on my trailer. I brought my 7 pin tool home from work and discovered I had several things not working. I crawled under the truck and holy crap! The wiring is a mess. Lots of electrical tape, scotch locks, and splices. I don't even know where to start! My question is there a place (other than a junkyard) to buy a replacement rear chassis harness? I have searched and come up with nothing. My truck in older (98 dodge 3500) and I can't find anything. If no one makes them then I guess I'm stuck rebuilding the one on the truck.
