Ditto on it being factory installation. I had already purchased the factory tow hitch and wiring harness from the dealer for about $580 total. I have an appointment this Tuesday to have it installed along with a 7-pin controller harness and P3 Tekonsha brake controller. They need to run power and from the battery and brake wire to brand new 7-pin adaptor. The factory only comes with a 4-pin.
I'm trying to get a better feel for how far below the rear bumper the hitch will be (I have a steep driveway at home/work).
