https://www.gmupfitter.com/ will have any information you could possibly want. navigating their website I have found to be a weird layout.
Most of the time I get lucky by typing out in google gmupfitter wiring diagram then type the make model and year of the truck
But just going to their home page I end up not finding much.
Others here may have a better ways to find data on that site. But trust me anything you could possibly want is there.
