I located and connected my trailer aux power and brake wire this afternoon. They were located under the brake booster wrapped up with lots of tape and held to the fire wall with a clip. Clip was an PITA to remove from the wires. After I got them free I connected the aux power to the proper terminal on the factory fuse box using an old nut from a broken aux light (finally random junk that became useful), 1/4 of my tube of dielectric grease, and some washers. Since I don't have a brake controller yet I just routed the wire in to the cab and zip-tied it out of the way.
