Stereo wiring, 2002 Trailblazer

[sdowns]

Hello,
I've searched many forums for info on the correct stereo wiring for my SUV.
I am trying to add an amp for a kicker box to my bose stereo system. The deck does not have any preouts so I need to add one thru the speaker wires.
The problem is, I don't know which wires are which...

The main connector to the deck is layed out:

A1 = Orange, A8 = Tan, A9 = Dark Green, A10 = BLack, A11 = Blue,
A12 = Black wi White Stripe

B1 = Orange, B4 = Brown wi White Stripe, B5 = Black,
B8 = Brown wi White Stripe, B9 = Brown, B10 = Orange wi Black Stripe,
B11 = Lime Green

If anyone can put a label to these wires, I would really appreciate it.

Thanks
