    Dimming Gauges Wireing

    I searched around for info about this and didn't find any definitive answers but i gathered some info and tried this and it works with mechanical gauges.

    if your putting gauges on the A pillar a good place to power them is the fog light or cruise control switches.

    Both switches have a purple and orange wire, Purple is positive and orange is the ground.

    Apparently there is a current in the orange ground wire that makes the lights dim.

    So crimp the gauges ground wire to the Orange and your gauges will dim with the rest of the console lights.

    .. as an addendum, if you are running an EL guage, or any guage with a common ground to power and the light, then just use the Purple wire.

    to dim my gauges, ive used the stock harness for the OEM boost Gauge, its located in in the harness for the CD player, just use some spade connetors to tap into it

    it seems that subaru uses the negative to dim.
