Daleo Kelso this will only work if your truck has the trailer towing package. If it has been wired aftermarket, you'll have to dig a bit for it. For the truck equipped with the package:

Fuse F31 will be for the parking lights on the trailer connector and Fuse F58 is for the trailer connector backup lights.

Check #67 under the hood behind radiator. There is a fuse box there. I had same problem. It's a 20 amp blue 1cmx1cm square style with clear window at top. A simple continuity test will tell if it's bad.
