Somewhere in my big book of projects, I need to redo the wiring on my car trailer. Just a plain old 18' hauler. I know the wiring schematic, just looking for ideas on execution. Not sure if I want to add a breakaway switch or not. I probably should. One idea is to put a 7 way connector on the trailer like the truck and have a doulbe male ended patch cord to connect the 2. No hanging wires to catch. If I get 7 conductor trailer cable, I basically have to cut the jacket off at the axles to pull the brake wires out then just run the remaining wires for the lights. Or I could get a parallel pair for the brakes and the 4 conductor wire for the lights. I might also need a 7 stud junction box on the tounge as well, if I do the female connector on the trailer as well. Any suggestions? Want to keep it simple so trouble shooting is easier as well. I have had this thing for about 15yrs and its finally time to fix the wiring, and make it last another 15. Interesting how I never had any issues with it till I loaned it out. Now if someone needs it I will do the pulling. lesson learned.
