ok since im bored at work and im gonna be hooking up to my trailer tomorrow i thought i would ask you guys what to do/ check tonight..
2002 F350 6 speed
i bought the truck with a controller already in it. has not worked since i bought the truck. 2 weeks ago lol
what are some things to check or test or to look for? i have another controller at the house. i could just tap into the ol wires and check that way to eliminate the controller.
the lights and signals work fine on the trailer just no brakes.
