Hey guys,

Finally got my m3 style mirrors with signals in them and they're also power. I had em painted and they're ready to be put on, but one problem:

On the stock mirror there are 4 wires to control the mirror, while on the new mirror there are only 3. ?!?!? .. yea i know i know.. that's what I get for buying from ebay. Anyway, I would still like to get these to work; the signal wires are simple enough to figure out, but I was wondering if anyone knows of a wiring diagram that will tell me what colours are what for the existing mirror controls?

Any help is much appreciated!
