Can anyone Identify this MOPAR thermometer. Where does it mount?

Wherever you put it. It's an aftermarket Mopar accessory.
well the orientation of the MOPAR logo is side ways. I thought it might mount to the drivers mirror because of the alignment of the logo and the red line. It has a threaded hole in the lower back side and is hollow in the back center with a center tube like a deer whistle. I thought a hood ornament but the logo would be vertical and the is not viewable from that distance. to see the red line and temp it would have to mount on the drivers side and then the logo would be horizontal. I doesn't seem able to mount to my Cuda's LH mirror.
