The wire colors are Pink/Black and Blue/Red. Where are you going to mount it? If you want the clinometer to dim with the dimmer switch you must use both wires!!! In the auto these wires are available under the center console and in all vehicles are available in the dash behind the radio. Anywhere there are lights that dim with the dimmer you will find those two wires. Use T-Taps to make quick connections. I use these wires in all my LED CoolKits...
