Fuse Locations for Trailer Turn Signals on 2015 Ford F-250
Question:
Can you tell me which fuse feeds the trailer connection on a f250 2015 ford Lariat. We have no power to the trailer turn signals. They work on the truck . all wiring looks factory.

The first thing you'll want to do is use a circuit tester like # PTW2993 on the turn signal pins in the 7-way trailer connector with each turn signal activated with the ignition on. The right turn is the pin in the 3:00 position, the left turn is in the 9:00 position. If you get voltage at each pin with the turn signals on, the problem is in the trailer wiring, not on the vehicle.
Ford isn't super-clear about identifying the trailer lighting fuses in their owner's manual for your truck. I've shown several different fuses in the engine compartment and the passenger cabin fuse blocks that they list as trailer lighting functions. I've highlighted in red the fuses you'll want to check.
I hope that helps.

Thanks for your help Mike. I appreciate it. I just hate I have to ask someone to point out locations of fuses. I think Ford should properly label their product so anyone could find the trailer light fuses.
