Let's see what we can figure out together. Below, I attached the wiring schematic for the power window circuit specific to your vehicle. If you can provide the year of the Yukon that you got the part from, I will provide those as well Then, we can figure out if it is even possible.
Let me know.
See pics below Note: I had to cut the pic in half to make it readable for you. I did overlap them so you can follow from one to the next.
