Dei 530t Help!

[Steve2500]

I need some help, I have a 2006 2500HD Silverado, I want to install 1 DEI 530T, and a WCM-1. Do I need to run all wiring to each individaul door or I've read online people have hooked everything up to the driver switches, but if thats possible what about the motor wires? Also does anybody know where I can find a wiring diagram, so I can identify what switch is for each window.

 

Thanks
