2013 GMC Savana, Alarm/Remote Start, Stereo Wiring

Hi all. I would like to have a wiring diagram for the stereo system in my van. I have the factory top level system one step down from the navigation. Bluetooth, usb control, 6 speaker etc. The front door speakers are 6 1/2 coax. (gone is the separate tweeter location higher up on the door panel that I have in my 2002 express.) The rear doors look like 6x9's The rear sound bar has 4x6's I also need to add heated power mirrors. I am hoping the wiring is there already. But if not, I need to see the diagram for the factory set up. I am hoping that the BCM is not involved in any way. Just a wire to the defrost circuit, and then a hot wire to power the door switch for the adjustment motors. If I get ones that have the turn signal, I am hoping I can just splice into that circuit as well. Thanks very much. Corey.

Thanks you very much for this. I would like to add that I found this link online which has tons of info. https://www.gmupfitter.com/files/media/photo/524/2014%20GH%20Van%20Elec%20BBM%20SI%20Brief.pdf also https://www.gmupfitter.com/files/media/photo/449/2013_GH_Van_071713.pdf Lastly, when I pulled my door panels, the wiring for the power mirrors looks to already be there. There is even power at the harness even though I cannot find the fuse location.
