Has anyone figured out how to get the wiring for a backup camera on the Roadster from the outside of the car to the trunk area. I have read all the threads, taken all the removable panels out of the trunk, am able to see all the wires in the trunk and have figured a route from the trunk to the new headunit. I have tried to run a fish tape from the passenger side marker light to the hole in the bumper fascia behind the license plate as demonstrated by someone with a Coupe. Maybe that works on the Coupe but not on the Roadster. I am baffled. Help please.
