What is the little thing sticking down from the underside of the passenger mirror of my 2015 Super Duty 6.7L King Ranch FX4 Crew Cab 4x4? I didn't have my phone with me today when I found this "thing" while wiping down The Big White Beast 2.0 (the name that my son gave her because my last one was wait for it, The Big White Beast). I checked the driver mirror and it doesn't have one on it.

 

That would be the outside temperature sensor sir.

 

10-4, Thanks Chad. That little dude was screaming today when I jumped in my truck at lunch (105*), Yow!!
