Where is the Trailer Brake control harness...
Please help anyone, been looking for the plug (if there is one) under the dash of my 05 F350. There is a trailer harness in the rear of the truck i can follow it all the way up to the cab, it has the blue and orange wires in the rear harness. I can follow it up to a plug then the harness goes into the cab, my truck does have a trailer brake fuse, Trying to install an aftermarket controller and need to find harness, apparently it has all the wires i need for it, practically plug and play. The truck does have the bare 4 wires that go under the hood and under the dash but dont really want to use them if the truck already has the controller harness. Please help anyone thanks. Need to tow something tonight :/
