    when i installed my boost gauge the back like was so bright it was blinding so as a short fix i wired it in to the dimming of the clocks but everything on the dash looks dim and i need a way of just dimming the gauge im guessing a need some sort or resistor but what wattage or ohms would i need or is there a variable one i can get

    i know it doesnt help you but i left my boost light disconnected for that reason... reminds me of an mr2 turbo i had a few years ago, it had 3 gauges in a pillar pod and a hks turbo timer on the dash, double din lcd radio/dvd and an avcr all beaming in my eyes lol... was pretty much un-drivable at night!

    sure someone will come along and sort it for you...

    i'm not great with electrics, but i think you should be able to get a variable resistor and stick that in, then switch it to what you want it (basically a dimmer switch) hopefully someone that knows a bit more about that kind of stuff will be able to recommend one (if it's possible)

    a variable resistor would be perfect just need to know where i can get one and what wattage and ohms i need i dunno why the gauge has to be so dam bright

    Drop JayA3 a message as I know he's put a resistor in his to dim the brightness.

    I hooked my one up to the dimmer that dims the interior lights.

    That way they all dim together.

    Surely you can just run the illumination wires off the cigarette lighter terminal's ? That would dim it and be easily accessible enough ?
