| On my '09, there are two Red/Black Aux Power wires located under/near the under-hood fuse box. One is taped to the harness between the fender and fuse box. The other is taped to a different harness between the engine and fuse box. This one was actually pushed under the fuse box and hard to find. Also, there is a third Red/Black wire which is for the trailer brakes, which was/should be already hooked up to the stud on the fuse box closest to the engine.
To get Aux Power to the rear bumper you have to hook up the Red/Black wire that is located between the Engine and the Fuse box to the stud on the front of the fuse box that is furthest from the engine If you have a 5er or a truck camper, you need to hook up the Red/Black wire that is located between the fender and the fuse box and add a harness under the front of the cargo box. You do not want either Aux Power wires on the same stud as the Trailer Brakes.
Both of my studs, in the under-hood fuse box, already had 40 Amp fuses in their circiuts, which are located just inside the fuse box by the studs, under the cover. Both studs are on the outside front of the fusebox, but under the cover. Apparently, GM stopped inserting dummy fuses.
