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.

I found out that the harness i need is 120$ because of the onstar and bose.

its probably worth it.. ghetto wiring it up will probably work, but only after countless hours of headaches and problems.

Try Ebay. I got mine for about 40 bucks shipped.

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
