Terry,
Sounds like a difficult task.
In "normal" cases would you have to connect the matching colours from the mirror to the car - and in newer BMW's are we talking about 4 wires, Red, green, gray and black for operating the mirror.
I think that your white should have been the green wiring, so I would try red-red, white-green, black-black.
Or try call the manufacture of the mirrors - they will know for sure how to connect. |
