a Positive Side Control or a Ground Side Control? I need to know because I finally installed my boost gauge into my newly installed 2000+ center console and I need to wire it up to make it work.

TIA, mrgreek2002:thumbup:

Should be three pin connector on the instrument cluster dimmer. Terminal 2 (gray wire) is switched positive from the headlight switch, terminal 3 (gray/blue) goes to load and terminal 1 (black/brown) goes to ground. Dimmer is on positive side of load.

I found out that terminal 3 (gray/blue wire) is the wire to hook up your things to (W8 overhead console, Boost Gauges, etc.) in order for them to light up and for you to be able to dim the light down. This is the only terminal (3) that you should hook up anything to.
