Hi,
Mercedes W447 V Class 2022.

I am trying to find a 12V that becomes live when I unlock the car, sort of like a timed circuit. Have it on another car I have, that when I unlock the car or open a door the ambient lighting comes on. If nothing else is done, it stays on for a certain time, then goes off. If the key is inserted or car is started it obviously stays on.

Does anyone have an idea which circuit I should be looking at?

Cheers,
Sean
