Current circuit diagrams 3.6l switches

Hello

I need circuit diagrams for the 3.6l switch because I have the 3.6 motor (automatic) installed in a switchcar (B4 quattro) and the throttle flap poti is connected to the gear control unit now would intruss me like that at the switch.

I have already measured whether the gear control unit passes the throttle valve position in some way to the Motronic, but I have not come to any result.

Thank you in advance
