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.
