Regarding wiring, I have a factory tow package, so there's already a trailer jack wired up at the back bumper. It uses a Pollack style connector on the vehicle side, so I bought a Pollack gooseneck harness kit that goes in between the trailering harness and the trailer connector on the bumper. I'm tapping into the trailer accessory power wire on the gooseneck harness, then running power and ground from the gooseneck harness around the bed to at least three locations. This isn't done yet, but should be an easy job. For the moment, I'm focused on getting the race car ready. The purpose of this modification? To give me easy to access power for my laptop and such at the track! And DC power adapters for your laptop are a lot less fuss than an inverter and regular laptop power adapter.
