I am looking for color wires to headlight switch, which color wire for fog lights. on 2007 dodge ram 1500. my headlight switch dont have fog light switch. I might need to hook up new wires to that color wires(fog light) to hook up aftermarket switch.

 

Why don't you just swap it for the factory switch? Or are you bypassing all the factory wiring altogether? If you are, be very careful what you tap into with your CAN bus vehicle; the electrical systems in those vehicles are very touchy and sensitive to voltage loss and spikes.
