OK.. I just installed my reverse glow white face gauges and a pillar gauge pod. I have everything connected except the power wires to light the gauges up. Now I already found a good ground source (near the fuse box).... so whats the best place to install the power wires? I want to use the headlight knob to turn the gauges on and, if possible, be able to use the knob, when turned, to dim the lights. So where and which wire do I need to tap into to achieve this?
