If you want to run the 4-way under and outside the vehicle, there are a few extra steps. Find an existing hole in the frame or drill an access hole to route wires from the harness out of the trunk. If you drill a hole, you will need a grommet to protect the wires once they are threaded through. Then cut the wire of the harness in half. Take the half with the 4-way and thread wires from the outside back through the hole. Reconnect cut wires inside the vehicle.This will void the harness warrenty.
Can you not install the wire so that it is located externally under the hitch? I hate having the wire go through the tailgate.

@cervelott : Ever figure it out? Wife decided she liked the '07 better than '08. So, am interested.

@etrailertv : Thanks. I found a plug that I was able to cut a slice in and then pass the wire through, sealing with Duct Putty.
