Kebab Talerken

Hi guys,
I have a Q5, 2012 model with automatic swing hitch towbar system (don't know the name of it). The socket needed to be replaced, and so I did. However, I forgot to take a picture before I removed the pins, so now I don't know which wire should go to what hole. I have used many hours to find the right scheme/diagram online, but the colors are not the same. I have removed all panels in the back, to locate the control unit 8K0907383D.

The wires that goes out from this box and into the socket seems to have numbers. If I can find out which wire that should go to each position of this contact, I can understand where they should go in the socket. Best would of course be to have the correct diagram for the socket, with correct colors. However, it seems impossible to get it... Her is the wires for my socket:

If I know that these wires are for, I can put them in right position on for the next picture

These are not in right position now

Any help is much appreciated!

Cheers,
