tahoe 03 bose system

guys i been searching for information about how to hook up the wiring harness in this car Chevy Tahoe 2003 Bose System w/rear audio control. Here is the problem, the radio was stolled and the wires are cut out so i don't now were to connect, there is a 24pin connector and 13 cut wires without the connector this wires are Blk/Wht, Orn, Pink, Gry/Blk, PPL, Brn, Grn/Wht, Grn, Tan, Lt Grn, Orn/Blk, Bare, Blu, Blk, Bare. Should i hook up this wires at a 24 pin connector or at the 12 pin connector and what is the schematic please.Thank youwilomar

I forgot some thing else there is another Orn thin wire i guess data wire. The radio is unlocked and when i hook up the 24 pin connector the radio works every thing except for the volume that is low, so if this works with an amp. should be very loud.wilomar
