I have an 01 Grand Prix GTP I need some help with replacing the stereo with a new deck. I need to know what wires are what. The color codes or something like that. If anyone can help that would be great.

I tried that but there is no damn "tan" color and It Says there is 2 browns. light blue and a dark blue but there is no light blue. there is 4 other wires that are odd colors like pink and red.

It has OnStar and the Bose system.
I got my deck to turn on and hooked a small speaker and tested the 8 speaker wire and it works but all the diagrams about the colors for the speakers are wrong. I hooked up the stock deck and it works fine. Im normally pretty savy when it comes to electronics but this is so confusing.
 


its probably worth it.. ghetto wiring it up will probably work, but only after countless hours of headaches and problems.
 
yeah buy a harness cause gm 2000 and up have no switched voltage behind the radio if its the harness i think it is . especially if its got onstar cause your keyless and dome light supervision goes through the radio and the dinger for the headlights is also interfaced . BUY A HARNESS please
