First off, my constant and ground pins on the Metra wiring harness are correct. So harness to harness to there. Incidentally, none of the other pins in the Metra harness line up on the Audi harness but from what I can tell, I don't need them anyway.
Secondly, I've run both separate and harness ground wires and tapped several 12v switched positions (sunroof, garage door opener, climate control, seat heaters, and cigarette lighter) in the fuse box via fuse taps with up to 60A of fuses and the HU still has no power (while everything else runs fine.)
I'm stumped. Mike said he might have some time this week to look at it but until then, any thoughts? I feel like dumbass for something I've done before...
