I have a generic Rees hitch that I picked up from Wal-Mart for $90 and bought a wiring harness online for around $50 or less (can't remember the exact amount). Wiring harness plugged right in bedhind the rear right panel. I don't have a mount for the plug on the hitch so I just tuck it up inside the rear bumper and pull it down when I need it.
