PD Motor for Snowcat: Conversion & Performance

Hello,
I am currently in the process of installing a PD motor, model MBK: ATJ, into a small tracked vehicle.
Now, I'm experiencing the following problems:

-The AI (or control unit) that I received with the purchase of the engine has the number 3BO 920 822 A.
According to my research, it appears to be an AI system developed by Benziner.

- Another issue is that this cable harness doesn't include an OBD connector!
To which pins is it connected?

The engine is from a Passat 3B, first registered in June 2000.

Hannes.

The AI is a 260 km/h car powered by a TDI engine.

Pin assignments, see wiring diagram?

Thank you very much.
I'm relieved that the AI issue is resolved!
I only need the wiring diagrams for the ignition coil and possibly for the ignition switch, specifically for the reading coil.
If anyone has a spare OBD connector, please contact me.

Best regards, Hannes.
