Audi TT Seat Heater Wiring Diagram

Hello.

Can someone please provide me with the pinout diagram for the seat heater switch from an Audi TT?

I installed the switches and heating pads in the seat bench of my Golf 4, but I'm missing the wiring diagram.

I haven't received a response from Hela after I contacted her. The helpful person either doesn't want to or can't help me.

It would be great if someone could tell me the pinout.

greetings
