Lighter socket wiring, which is live?

[Trefor1]

Hi chaps.

Can someone tell me which the live is on my CLS's lighter socket cabling? i'm hardwiring a dashcam (with a 12V > 5V kit). All has gone smoothly so far.

Thanks.

Trace which wire goes to the centre pin of the socket and that's positive. Also you can trace the wire that goes to the metal outside surround and that's the negative. Alternately pester a mate with a multi meter

Brown should be the earth, red live and the small cable is the illumination.
