I recently purchased a trailer brake controller for my 09 silverado. I have it all mounted and hooked up to the truck wiring harness, what I think is correct. I have been told that there is a power wire under the hood of the truck that needs to be hooked to a hot post on the side of the under hood fuse panel. Problem is I cannot find the damn thing. I have looked several times for this wire. I found the positive wire that needed to be hooked up for the aux on the seven prong trailer plug but can't seem to find the other wire for the brake controller. Anyone found this wire?

Just run it to the battery if it does not need to be a switched 12v.
