Hi Guys, I know this is an old thread, but I was in the same boat as a lot of you, am installing a Kenwood head unit in my 2009 Sierra Denali. Could not find the black connector with the blue and white wires anywhere, after much reading and researching, I saw Walt’s reply in this thread and looked close at his schematics, I had the GR/Blu and Gry/ OR wires up at the mirror, and traced them back down by the distribution block to the left of the brake pedal, they go into a white connector, not inside the block , but to the left of it. I tapped into the wires there, , and it works great .just wanted to share. Thanks.
