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.
