need help with what wire does what

[dumpd6]

ok well now i have my car back on the road it is driving me crazy not having a juke box so ive decided to put it back in the only thing is there isnt as many wires coming from the car as there is coming from the head unit... there are the basics red black yellow and blue an white for power earth memory remote and speakers but there is still a yellow and black (dont know what that is for) and then a orange and white (dont know what that one is eather) the stereo use to be in there so the wires have to be there some where but i dont think i colour coded the wires when i first put it in so if some one could tell us whats what incase i have to run new wires.. by the way its a pioneer deh-p6350( the one with f1 cars and eagles) if thats any help
cheers

I think the orange/white = illumination (dimmer) and the yellow/black = telephone mute

so does that mean i dont have to hook up the yellow an black

l asume you don't need these connected. The telephone mute was on calais and up (l think it was an optional install, but my pearents calais has it) and the dimmer, well, l don't know.
There is a wirring diagram on the justcommodores site for download that you can use, also you should have gotten one with your headunit. Otherwise l suggest taking your car and headunit to an autoelec and getting it installed. l had my new headunit installed for $50.
