According to the owner's manual a 2014 Ford F-150 has the following fuses or relays for a trailer (the numbers will be their position in the power distribution box):

- 6: Trailer tow park lamp
- 9: Trailer tow battery charger
- 17: Trailer brake control
- 21: Trailer tow battery charge relay power
- 37: Trailer tow left stop/turn
- 38: Trailer tow right stop/turn
- 39: Trailer tow back-up lamps
- 43: Trailer tow back-up lamp relay power
- 67: Trailer tow park lamps relay power
- 73: Trailer tow stop/turn lamps relay power

I have also added links to a pair of help articles on trailer wiring, including a troubleshooting guide which I highly recommend taking a look at.
