Trailer Tow Wiring problem ?
I have a 98 F150 with the trailer tow package. It came with the 7 pin round wiring harness. I have no turn signals or brake lights, but the clearence lights work on the trailer. The trailer lighting works fine on my brothers truck. I replaced a blown fuse in the fuse box in the engine compartment and checked the fuse pannel in the cab, no bad fusess in the cab pannel. I also replaced the 7 pin wiring harness on the bumper and still no turn signals or brake lights. What else should I check. Thanks for any help.
