I've looked through the forum, and visited crutchfield.com, and
I've found the right harnesses, but what I'm asking is there a harness that takes care of
Everything?

I have a 2013 silverado with Bose system, with a pioneer app radio 3

I've found one that's for the steering wheel controls, and I found
Another one that is for Bluetooth, onstar, satellite radio, etc.

But what I haven't found is an all in one. Or can I run two to the same
Head unit?

I think there has to be 2 harnesses to get 'all' the factory stuff going.

You have to buy both... I have not seen an all in one. 05 w/ bose,onstar,etc here.

I used the pac RP5-GM31. It does everything. Turn signals not very loud but everything else works great!

Reading the reviews on that be careful to get an up to date harness... that was the biggest complaint
