You can look for the fuse and relay associated with that circuit and replace as needed to activate the 12 volt accessory circuit of the truck.

Or, you can bypass the factory wiring and run a length of 10 gauge wire like part # 10-1-1 (sold by the foot) through a breaker like part # 9510 to the 1:00 pin of the 7-way and you'd be set.
