8-Pin WFS Connector: Find the Right One

Translated on 31-10-2026, 11:04.

Hello everyone,

I'm currently installing an AHU (Air Handling Unit) in my T3. I'm having trouble with the correct wiring of the WFS (Window Fan System). It has an 8-pin connector. I have the pinout diagram for a 6-pin connector, but what about the 8-pin version?
Can someone please help me?
Is there perhaps a general collection of VW connector pinouts available somewhere online?

Thank you and best regards,
Peter.

Hi,
I think I can help you, I need to check the "big" VAG folder tomorrow. I'm currently wiring my T3-AFN, and I have a yellow cable left over at the diagnostic connector: 1x plus, 1x minus, and a gray-white cable for the control unit. If you have any ideas...?
