Dude I gave you the thing yesterday for your car.

Black wire = Ground it, somehow contact it with the body metal.
Yellow wire = Ignition [black/yellow, Yellow, or Blue/White] (apparently CRX has 3, my car only had 1.)
Red = 12+ power [white/black]

Take your center console out and look at the mess of wires behind your CD Player. It should have the stereo harness wires twisted together to an adapter harness, they are just twisted together and held with caps. Just undo the caps and twist in the LEDs wires to where they should go. Most of the stereo stuff actually says what it does right on the wire. Shouldn't be hard.
