What can you not find? My advice leave it alone! Or carry it to a professional, if you are a professional installer, then my apologies!

The diagrams are for the BCM, which has no radio control which is linked to the RAP feature. If I remember right there is no analog wire for VW for RAP. It is all digital controlled. Unlike GM's.

Thanks for helping , what i look for , is only the negative trigger for the door lock , i am pretty sure the wire came from this BCM , if i don`t find anything i will strip my driver door trim , and look for the right wire , but i am a bit lazy posted_image

Although it does belong to you, you cannot afford to be lazy when working on a vehicle of that nature!

The wire you are looking for is the wire going up to the dome light which switches to neg. when the door is opened. This has a 1 minute delay on closing the door.
Why this wont work:-
Going into the BCM box to pick up an individual door wire will require lots of skill with diodes, think DEI 1076, that circuit shuts down on power after 10mins. if the door is open, the radio doesn't have an ACC, it's all CAN data, play with it and you will have frequent expensive visits to people with diagnostic equipment.
It's all unnecessary any way because even with the key out the radio should stay on for up to 1 hour.
