I purchased the Raxiom turn signal mirrors for my 06 Mustang GT. I installed the drivers side without an issue. But when I went to wire in the passenger side I am stumped. No plain black ground wire visible and unsure about what color wire is needed for the positive connection. Is there even a ground wire on the passenger side of the car and if so what color is it? Also what color will I need to tap into for the positive connection?
If anyone could please help it would be greatly...
