I have a 2007 e90 that I bought about two years ago. When I got it, there wasn't a cover over the rearview mirror cabling (and what I imagine is the rains sensor? I hadn't really thought about it, because I wasn't driving it very often. I'm driving it more now and I'm getting a little annoyed by the hanging wires.

So, I'm hoping you guys can help me on a couple things:

-What's the third set of wires coming out of the wiring harness?
-I know this question is probably for another forum, but: What's the correct part number for the cover? I've found part# 51167076129 in a fair amount of places, but I've seen other options as well.

Thanks guys
