There is a wire that needs to be attached to the relay box under the hood of your truck to activate the 12 volt power circuit.

The ring terminal for the 12-volt power lead for the 7-way trailer connector is located to the left of the power distribution box. It is taped to a wire harness under the power brake booster. Cut the tape to release it from the harness. Then run the wire to the front of the power distribution box and hook the ring on the right post (M8 stud).

I attached a help article that covers more of this process for you to check out as well.
