12v feed for rear fog light


Recommended Posts

My rear fog light is not working, I have narrowed it down to the switch not getting the 12v feed. I am not sure where it comes from as the cable gets lost into one of the 3 groups of cables that connect to the airbag ecu under the armrest, hope that makes sense.


Will it be OK to tap into another 12v feed, open to suggestions which one. Ideally I want a switched 12v source.

Just find a 12v feed that becomes live when the sidelights are switched on.

Most people take the feed from the dash dimmer switch - it sounds like whoever did yours used either the circuit for the auto shifter illumination (if applicable), or the ashtray lamp
