W204 power seat controller wiring
I recently bought a stock w204 power seat which has a controller model A2048209785. Also I have a switch unit from VW Touareg (PN:7L6959766B). Now I want to connect the switch unit to input of controller but I do not know which wire should be connected to controller input. The controller output is factory connected and should be working. On the controller lable (input side) noted "1 (schwarz) CAN, Vers, LS", any body knows what does it mean and how to connect the switch with 11 wires to controller input with 20 and 3 pin sockets?
Any help is highly appreciated
