2009 Silverado Factory radio BTA850 FAST wiring help needed!!!

[Bully00]

I have spent 2 hours trying t figure out my buddy's 2009 Silverado factory wiring diagrams and I am stumped. I wired my Jeep TJ in about 10 min. I finally got power but no sound. Do they have something built in the system that is preventing successful install?

Where do you have the connections for the Tube made? What factory system does the Silverado have?
