    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?
    :idea:
    There are four wires in total in two pairs:

    Blue/grey
    brown

    Green/grey
    brown/white

    any help would be much appreciated!

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