Unfortunately the ProSport gauges don't dim. The lights are either on or off. For the wiring there are a couple different choices depending on what color you want them to be and when. Since I only wanted mine to be red with a white dial all the time the wiring was easy. All you have to do is put black to ground, red and orange to ignition.
If you want to have the gauges switch from white in the day to red in the night, then you have to add in the white wire to the parking light switch.
All 4 wires are located in the radio harness if you are going to be near there otherwise the fuse box will have them also, you'll just need a clean way to top into it.
Let me know if you need any help further!
