I don't remember all the colors (don't have them in front of me) but most wiring harnesses match the color of stock. You'll have a ground which is black, a 12V lead that turns on with the ignition (I think is red), a constant 12V lead (I think this is yellow), a dimmer lead (not sure what color this will be) and nomrally a low voltage lead used to turn on amps or sometimes power antennas (this is normally blue). Its been a long time so don't hold me to the colors and I'm just doing this off of memory. The best thing to do is use a volt meter and connect it and measure what is coming from each lead to determine what it does.
