I don't know. Some of the descriptions that I came across were fairly radical (dual climate control yadda yadda yadda). GM uses this everywhere in the lineup as well.
The harness loom that the wire come off of is the one in FRONT of the radiator. You can't see it from the engine bay, the actual harness runs between the radiator and the front bumper cover. There is just a small loom with the one connector that comes down off the main harness for the sensor. I think you'd know if it was there since you just did a bunch of body repair. There is also a hole in one of the plastic air dams that the connector harness runs through.
(hope that helps)
