I installed them with little problem, but now I cannot get any power. The line from the car has power, but the line coming out of the gauges doen't read anything on the voltmeter. Any suggestions? I need help fast.

 

I contacted the seller, and he had this to say:

Connect all speed-glow wires from each face to the supplied resistor (black or blue box) Locate a solid ground and attach the black wire to it. Locate the power source, which is connected to your parking lights, and attach the red wire to it. (DO NOT USE YOUR FACTORY DIMMER FOR A POWER SOURCE) This would result in a failure to light your speed-glow gauges or burn them out completely

But I know lots of you used the dimmer switch...anyways, where can I find the power for the parking lights?

And also, where did you all mount your dimmer switch?
