Installing a new cd/radio/headunit

[Fossil]

Hoping someone might be able to help. I'm installing a new cd/radio/headunit into my 2002 T4 and I need to know the "illumination" wire that lights up the dash lights of a night please?

No idea but a simple test with a multimeter might do it alternating between lights on and off..

its handled by the CAN bus in most newerVW's what Model/year ? you may have to splice into the lighting for the dash lights -

If you’re after wire which you can tap into? The easiest would be from the headlights switch, just remove it and you can piggyback from the wire there.
