Mercedes CLS lighter socket wiring

[Targarama]

Hi chaps.

Which is the live? I'm hardwiring a dashcam (done this before in other cars, have a 12V > 5V kit).



Thanks.

It wasn't a pisstake we are not all expert auto electricians with directorships and goatees. I just wanted to be sure. I could not trace the red or brown to the relevant positions on the lighter socket itself. I have now established that red is live and all is connected and working. I wanted a switched live so the camera only runs with the ignition on.
