Parts For Rewiring Trailer with 7-Way  


I am rehabbing my 16 foot utility trailer that has sat out in the woods for so many years when I stepped up on it I fell through the decking. So I stripped it down and painted it Red, White and Blue with Rustoleum brush on oil based paint took brakes apart and on two axle trailer and put new tires on it. Before I lay the new deck down it would probably be better to rewire, as the wiring even though in plastic conduit looks pretty shoddy, and I cant really figure out if manufacture even used any sort of color code on wiring, no breakaway on trailer with two 3500lb axles. Lights are working after some clean up of connectors that seemed cheap also. So I could really use the guide you mentioned that you could send please? Ill link you to a help article about trailer wiring that youll likely find helpful.

If you scroll down on this page and look under the Miscellaneous Media heading you'll see a link to a page that says Trailer Wiring Diagrams which is the link you are looking for.

It's probably best to start with a 7-way junction box like the part # 277-000141 which comes with a new 7-way ran back to a junction box that you can run all of the wiring functions to. We also sell jacketed 7-way wire by the foot too with part # DW04914-1 but in reality it might be best to run 10 gauge wire like part # 10-1-1 for the brakes and 12 gauge like the # 12-1-1 for the other functions.

Then for a breakaway kit the part # 3802308 would work great.
