AFN-MSG pinout

Hello.

Let me introduce myself with a request. My name is Frank, I'm 48 years old, married with two children, and I'm currently working on my VW T3 van. It has a 1.9 TDI engine (MKB). "I installed an aftermarket radio (AFN) into a Passat 3B from 1999 and am now working on the wiring."

I've found everything except the diagnostic cables (K-line).
It's not listed in the wiring diagram for the motor harness, and the electrician at the dealership couldn't help me either. Can anyone tell me where I can find this wire? The engine control unit has the part number 038 906 018 P and features 80 pins across two connectors.

I'd like to say thank you.

Frank.

Hello.

The K-line is located on pin 45 in the Passat.
and proceeds as follows:
Engine Control Unit (Pin 45) -> (Pin 5) Instrument Cluster + WFS (Pin 25) -> (Pin 7) Diagnostic Connector.

Okay, hier ist die Übersetzung:

Hello Wladi.

I will check that later. I hope it's the same for me.

First of all, thank you.
Frank.

PS: According to my plan, it should be a 0.35mm green/black cable.
