Message Installing an oil pressure gauge and I can't find a good variable voltage source for dimming when the lights are turned on. It seems that you have to hook into the ground and power of the dimming circuit to get the correct varying voltage to dim or brighten the interior lighting. I'm looking for a power only wire or source that varies without having to use the ground for the dimming circuit.

Any ideas? Is this possible?
