As this sensor's location is very often a mystery, maybe this pic will be of help along with part #. Maybe the one on some trucks looks something like this..

I called my dealer, he matter of factly told me it was in the mirror.... Two hours LATER, I dug it out from under the radiator. 2008 ProStar. Just saying. ;-)

And to add... That is not the Air Ambient Temp Sensor, just saying. No clue what that was you posted.
