It's the 12 volt accessory circuit for the trailer wiring fuse and/or relay that is bad on your Ford truck. Or it's possible the circuit isn't complete which you could do with 10 gauge wire like part # 10-1-1 (sold by foot) through a breaker like # 9510 from the 1:00 pin of the 7-way to the positive post of your vehicle battery.
