Stereo wiring diagram for 2006 Chevy Trailblazer?

[m_luyendyk]

I need to know the colors of what wires go where on a 2006 chevrolet trailblazer with a Bose system. Im hooking up an aftermarket stereo system and I looked on google and by looking at the wires on my car and the colors to what speaker that color goes to on some websites just doesn't make any sense. I hope someone has a different answer. Thanks!
