I know how to install the gauges and everything but there are two wires that I don't know what to do with them. I think they are the power wire, one is black and the other one is red. So where do i hook up the power line to? The dimmer switch? Thanks!

 

Someone mentioned before that if you unscrew one of the bulbs behind the gauge cluster and place the power wires there and screw the bulb back in to hold the wires in place, you can use the dimmer switch to dim the indiglos with the rest of your illumination.
