    Auto dimming rear light fitting help.

    Have ordered a Vectra C auto dimming rear view mirror. Been looking through at the guides and can't seem to find a definate guide on how to fit it.

    Can someone tell me what wires are needed to fit. Is it just an earth and a live I need going to it.

    Will have to wait and see if it is a Vectra one that turns up or if it is a zafira one!

    Black should be ignition +12v
    Brown is earth.

    Then the other 2 wires will stop dimming the mirror when either earth or 12v is applied.

    If black and white stops the light dimming when 12v is applied then yes.

    The other one would then stop it dimming when the wire is earthed and would go to the interior light.

    bringing up an old post but ive just got hold of a vectra mirror and the wiring isnt a problem now i know the colours but did you just cut the old plug off or splice into the wire?

    ive got hold of the vectra plug with the ribbon cable attached and managed to solder 3 wires onto it. The 4th pin on the mirror doesnt have anything attached to it

    I just snipped the connector off and soldered new longer wires on to it.

    Im having issues with this already FFS.

    Ive wired up:
    mirror black - black
    mirror brown - yellow
    mirror grey - white(creamy colour)

    im using the male connector from the centre console lights (if i was using the actual connector then it would be - car side)


    mirror black - grey/yellow
    mirror brown - brown
    mirror grey - grey

    but it doesnt seem to work still.
    even if i put a LED torch over the sensor it doesnt seem to dim
    also the centre LED underneath (for illumination) doesnt come on with the lights either

    what have i done wrong
    Its a MK5 so assume it might have different wiring colours.

    HELP!?
