    Boost gauge wiring

    evening all,

    Trying to hook up my new boost gauge, anyone know what the 12v+ and ground wires are on the back of the dimmer switch? after reading up i was under the impression 12v+ is blue/grey and ground is brown but just tried this and the gauge doesn't light up?

    There are four wires in total in two pairs:

    Blue/grey
    brown

    Green/grey
    brown/white

    any help would be much appreciated!

    If you are doing ANY electrical wiring on a car, buy a test light. They aren't expensive (http://cgi.ebay.co.uk/CIRCUIT-TESTER...#ht_1360wt_939) and this way you can punch through the wire's sheath and see for yourself if there is a 12 volt feed.

    Also, the back of the headlight switch is my preference 12 volt source for a boost gauge.

    Second this, that's where I got my feed from, and it works with the dimmer too.
