I put new lights on a old trailer last night, New deck boards and paint are in the future however for now I just need to be functional. It has brakes that need to be hooked up also. Since it was wired with a flat plug the trailer brake was just un-hooked. I rewired the plug on the truck side and located the brake controller wire as well as the 12v wire for a 6 way plug. I mounted my brake controller in the truck but stopped there. Wasn't ready to start messing with wires under the dash.
