Troubleshooting Light Bar Installation On 2015 Ford F-150

Question:

I have a 2015 Ford F-150 FX4 Pickup Truck and I added a light bar between the tailgate and the bumper. When I plug it into the 4 wire trailer connector, My dash always thinks I have a trailer on and the backup camera is different and the dash thinks I have a trailer on. Do you offer a solution for this? Perhaps a Yinch connector so I avoid this and everything works as it should?? Thanks,

Expert Reply:

It sounds like your light bar has been wired incorrectly. You somehow tied the light bar wiring into the wiring that identifies a trailer.

I recommend disconnecting the wiring for the light bar. Most have just two wires. One is typically white with a ring terminal and that is the ground which should be attached to a clean metal surface.

The other wire should be attached to a wire that shows power only when the running lights on your truck are on. You can use a circuit tester like part # PTW2993 to identify the wire you need to attach the light bar to. I have attached a link to a helpful article that explains trailer wiring and also shows what wires on a wiring harness are used for.
