Project complete. You can carefully pry the power outlet away from the panel. I ran a single wire from the liftgate thru the rubber conduit where I fished it from the removed center header panel and was able to (barely) run it under the D post panel and the door gasket and had to remove only the cargo net screw to snake the wire out of the power outlet opening. I used the backup light ground for both the camera and the relay. The backup light power operates the relay. Cost was $130 and the local guy was about $600 for just the camera and I also have a proximity sensor good to about 5 feet. I am satisfied with the results. Anyone thinking about a Hopkins 50002 Smart Hitch shoud be aware that it cannot run directly from the backup light power. While Hopkins support was accurate in everything they said, basically connect it correctly and it will work, they offered nothing to help me. I would recommend this product if you don't mind the work to get it installed.
I hope this will help another DIYer.
Thanks again for all of the great information I've found here. Next project, DRL.
