    Hi All,

    Which wires in the roof console are best suited to take for an auto dimming mirror? The mirror needs to take it's power when the ignition is in the 'on' position (not permanent power).

    I have the electric slide/tilt sunroof so I could I take the feed from that - although the sunroof still uses power when the ignition is off because it's operated by the keyfob when locking. So should I just take it from the light instead or could I have the loom/harness already installed? Fuse number 15 is responsible for the instrument cluster and auto dimming mirror (5amp) which is present in my fuse box.

    Any ideas from people who have fitted auto-dimming mirrors (OEM ones or not).

    Cheers.

    I had one of these fitted recently. Pretty sure they used an Audi loom but I can get some pics up later and show you how they did it if you like?
