According to your 2014 Ford F-250, the fuse number 26 (30A) is trailer tow park lamps. You will also want to check relay 29 for trailer tow park lamps. Fuse number 70 (10A mini fuse) is for trailer tow backup lamp and relays 74, 75, 76 are for trailer lights. You will want to check fuse 100 (25A) for trailer tow turn signals. Finally relay # 102 is for trailer tow battery charge. These fuses and relays are in the power distribution box in the engine compartment.

In the cab fuse box, you will want to check fuses 13, 14, 15, 30, 31. All of these are trailer fuses that are 15A.

You can use a circuit tester like # PTW2993 to check the fuses without pulling them by probing the hot side of the fuse for function.
