I bought an auto-dimming mirror from Impex, number 3B0 857 511 H, and the unit I received has 4 wires instead of 3. One gray, 1 black, 1 white and 1 green. I was following the instruction in this how-to PDF where only a bk/bl, brown and br/bl wire are mentionned. I identified the following to be corresponding wires:
bk/bl = white
brown = black
br/bl = gray
This leaves the green wire. What is it for???
