Wiring diagrams for rewiring 1982 17 1/2 rd

Does anyone happen to have the wiring diagram for the 1982? We are looking to rewire to get all of our marker lights working and getting the tail lights to work much better and more consistantly. Already changed the old bargman out and put new lights on the back and sanded up inside the hitch and receiver. Not sure what else to do but rewire.

Hey Kathy,

No such thing really exists. If cleaning up the wire ends and putting new lights on didn't fix the problem, it's probably a ground issue. I seem to recall there are ground connections to the frame in a couple different spots, one toward the back usually and another I think near the junction box on the back side of the header frame is where your battery wires go to. Make sure those grounds are clean and contacting good.

Hopefully someone can confirm or deny this. I just vaguely recall those there, but I've never personally had an issue with them. The factory lights that came on your trailer were horrible for leaking, so usually putting new light fixtures on solves the problem for most people.

Sanding the inside of the hitch and receiver will do nothing for your ground. Your trailer connector will have a white wire in it and that is the ground between the truck and trailer. Before re-wiring the whole trailer, I would check the ground connections at both the truck and trailer. My guess is, that the ground point(s) in the trailer are corroded.
