Anyone have access to wiring diagrams for the overhead console in a 2012? I'm simply looking 12v accessory and couldn't locate it. I was looking at wiring up one of those homelink mirrors and it seems the wiring is a no go! I'm simply looking 12v accessory and couldn't locate it. I spent 2 hours with a voltmeter and digitial scanner and this is what I found

Blue plug for lighting with 4 wires
Constant 12v (always on)
Ground with resistance (about 3K ohm)? No voltage and not a complete grounding
Low voltage ( <1v ) appears to be canbus for door open
Low voltage ( <1v ) appears to be canbus for headlights and illumination

Black plug for sunroof with 4 wires
Contant 12v (always on)
Ground
Constant 5v (always on)
Ground

That's all there was. Any suggestions?

Unfortunately not. That was the instructions I was following. That's the correct blue plug, but the wires are not the same, and there is only 4, not 5. You can tell that's not a MK6 Jetta so I'm guessing that's valid for the MK5 Jetta and the MK5/6 Golf?

Guess if you think about it why would the overhead lights require an acc/switched supply? Doing some more research it seems you have to get the power from the block under the dash and run it up the a-piller.

Search for VW Homelink. Not finding the mirrors, but a visor instead. Think it's a part from a CC?
