Powering B5 AI: A Comprehensive Guide

I'm planning to install an instrument cluster (IC) with a FIS (fl multifunction instrument display) and additional gauges in my A4. However, I want to test the ICs before I buy them, and I don't want to have to install them every time. Therefore, I need to know which pins are used for the power supply and the K-line (for diagnostic purposes).

The AI has the number 8D0 919 033 N.

Can anyone tell me the corresponding pin numbers? I don't have access to the circuit diagrams at the moment.
