The pin in the 1:00 position on your 7-way is fed by the auxiliary power circuit. The wire feeding that circuit runs to the engine compartment and terminates under the brake booster and master cylinder and will have a ring terminal on the end of it. The ring terminal will connect to the front power post on the fuse box under the hood. A 40 amp fuse will need to be installed in the location closest to the power post to activate the circuit.

I have edited a photo for you showing the fuse box and the fuse and wire connection location. I have also linked you to some FAQ articles that you might find helpful.
