I looked and followed the loom from the hump on the driver's side behind the rear seat, along the side marker and around to the Passenger side marker. There is only one black wire at the Passenger side marker, and appears to be the end of the line. That black wire is power, like the wiring diagram says. I then go back to the tail lamp and the other wires are there. But there is no pigtail or other wire that attaches to the trunk pan or bumper support.
