Okay, well the mirrors have 3 wires a green white a yellow , but I don't remember if they r heated, don't think they r... And I still haven't popped the cover to see how many wires my car has, can u confirm a 1994 325i has 3 wires? My 320i sedan had either 2 or 4 I forget but it was different than the mirrors, got the up n down to work tho lol... For the fitment part of the install I checked forums n learned that I have to sand down the 3 pegs otherwise the mirrors will stick out an not look flush.. I gotta hit up ct n get wire connector thingys an sand paper I'm gonna put them on tomoro I figure if I play with the 3 wires I'll find a combination eventually lol
