Rear wiper not working on 2004 Yukon. I found a broken wire in the lift gate wire harness. Is this wire for the wiper motor?

Where on the truck is this located? I didn't see one that matched but we can try and narrow it down. Do you see the harness on this view?

Put a volt meter on it, and turn on the rear wiper switch. Do you then get ~12-14 volts on that wire? if so, it is most likely your rear wiper motor power wire.
