Just picked up a f900bt and need a wiring harness for my 06 trailblazer ss. I have done many searches but have not found anyhting that seems correct. Called a few local intall shops in the area and was quoted anywhere from $100 - $120...seems a little steep. Where is the best place to get the harness and which one do i need?

thanks

the reason the harness is so expensive is because the new GM's radio interfaces with the cars computer, signal to turn on and off, door chimes, possibly Onstar and Bose interfaces as well

base stereo trailblazer(non Bose) with Onstar - Metra axxess GMOS-01 $100 (crutchfield)

premium stereo trailblazer (bose) withOnstar - Metra axxess GMOS-04 $100 (crutchfield)

these harnesses also get reverse trigger(for back up camers), VSS,and parking brake triggers so you dont have to run them all over the car
