I'm trying to wire power to my CD changer and i must wire it to a switched and constant power behind the stock head unit. Does anybody know where these are located or how to do this. Also what does each color wire represent on the head unit.

 

I dont know the color of the wires but according to a manual I downloaded...

key on power is terminal number 10 or the 10amp fuse number 6.

Constant power is teriminal 6 or the 15 amp fuse 37.

Hope that helps at all, I dont know if the numbers on the harness are actually numbered but you could tap into those fuses and get what you need.
