I dont understand why you would need that unless you took off all the wires and took out all the plugs and forgot how the wires were.I have the same truck and I always do the plugs and wires one at time to make sure I make a mistake.If this is your ploblem let me know because i might be able to walk you though it.

the wiring diagram for the Yukon covers about 100 pages of a factory service manual, we do not have factory service manuals at fixya, i can direct you to a place to buy one on CD, it is very cheap and will contain all the wiring diagrams as well as repair and tear-down of all the different components of the truck.
