    Evening boys and girls.

    Havent been on here for a while, been in shagascruff for the best part of 2 weeks :).

    On my return home today i was greeted by a very nice parcel from a ex-s3 owner (coyle, cheers mate).

    It was his old stack boost gauge that already has a red film on the backing and has been mounted to a A-pillar for me.
    Now, who's fitted a stack boost? Any advice on wiring it up or can anyone who's fitted one shed any light?
    Wheres the best place to tap in for the power? The mechincal side or should i say the boost tubing side is easy and i know the best route for that etc.

    Any help would be much appreciated.

    Dan.

    Take the 12v feed from the headlamp switch, its purely for the backlight.

    Gutted i couldnt have this as my interior is a slightly different colour so ill have to make mine myself!

    I hope you've booked in to the clinic now you're back ;)

    I wired mine in so that the back light came on with the first turn of the ignition. If you remove the fuse box from the drivers side of the dash so you can get in there to get at the wires that plug into the back of the headlight switch.

    There's no take off on back of the gauge for a earth/ground, theres only a +/- feed and the vaccum feed, do i just earth it off bit of metal on the gauge?

    Haha, no need westle, i took the misses with me for some fun :) lol.

    - is the ground mate the best palce I found was if u take the fuse box out on the dash support near the bulk head you'll see a nut with 4/5 brown wire attached that's a main earth point unscrew the nut attach ur ground/- there n re tighten, as for + either tap off direct from the fuse for the side lights or off the main switch itself or off the centre console/ashtray light mate
