Thanks @Wino. I am interested in the signal wires which seem to be 6,5 and 3. 6 and 5 seem to have the same color code which is weird. Do you have any idea how the signal transmission works? E.g. I see 0.42V in VCDS which wire has this voltage?

Does anybody have the pinout of the lambda probe that is between the engine and the catalytic converter? It's a 6 pin connector. I used to get this stuff from cardiagn.com but now it seems to be broken...

Thanks, mate!

LPG ECU on switch. So no power requirements, just voltage has to be there constantly when ignition is on. Is EGR pin 1 a good match?

It's a BBY engine with Magnetti Marelli 4MV ECU. There should be a switched live under bonnet I guess but I fail to find it. Anybody found it before?
