    Ive fitted an AFR gauge in the drivers side air vent but wasnt sure as to which wire i needed to splice into for the dimmer function to work ( it is reflecting on the drivers door window ) i dont mind if it is dimmed all the time but will have to move it if i cant work it out.
    The gauge does have a wire to connect to the headlight wiring to dim it when i put the lights on... Is this a live feed or earthing out?
    Does anybody know which of the wires on the head light switch will work please .

    Many thanks.

    The blue/gray wire is your variable power and the brown is the ground, i used this guide here...http://forums.vwvortex.com/showthread.php?3003612
