Question:

My truck come with a factory brake controller. I have made the connections in the cab but dont have power to the controller. I found one of the two wires under the hood that has to be connected. I can not locate the one that should be next to the brake booster.

In regards to a 2011 Chevrolet Silverado 3500, the power ring terminal for a trailer brake controller like the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 is located directly to the right of the power distribution box. It is taped to a wire harness between the driver-side front fender and the power distribution box. 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 left post (M6 stud). You may also need to activate the brake controller power post by inserting an automotive style 30-amp fuse into the correct slot in the power distribution box. I have attached a photo below of the connections.
