05 GMC Yukon xl coolant overflow tank.

My wife's 05 GMC Yukon Denali xl has a leaking over flow tank.I purchased a new one I noticed the new one and the old one have an area that you can plug a sensor in.I have searched high and low for the pigtail and can't find it.My 02 Silverado has it loomed in with throttle body wiring.I have unraveled the throttle body wiring on Yukon and can't find no evidence of snipped wires.Did they move that sensor to a different spot in 05 or am I dealing with someone else's butchery?
