Hi all,
I want to use the door open switches (rear doors) to turn on some 'puddle lights'.
Does anyone know if they operate by switching +12v or grounding, or do they connect via some kind of data bus system (Canbus?)
Thanks

Pretty sure it is by grounding. This guide is about wiring door sills to the door switch. W203 Door Sill Install
