hi there, new to the forum. need help with m-tech mirror wiring. my original mirrors only have 4 wires: black, brown, blue, and white. the m-tech mirrors (off a wrecked '95 540i sport) have nine wires: black, brown, white, green, yellow, orange, pink, red, and grey. i'm guessing the extra wires are for memory control, which i do not have. can anybody point me in the right direction to which wires to splice? thanx in advance!
