Mirror tap wiring question

[Dubious]

I have a mirror tap for my 9500ix Radar detector and was curious if anyone knew the pos and neg wire setup on the rear view mirror harness?

Thanks in advance!

I think a good one is a tiny red/blue wire that goes into the actual sunroof MOTOR itself (NOT the switch harness). It's 12v+ with key on and stays live until you remove the key. Or open the drivers door..can't remember which.
Always test to be sure, but just did it the other day on an A4 and it's the same.
