Need Help Figuring Out A Piece That Felll Off

[ProtonXX]

Theres a plug that plugged into to a nozzle shaped adapter on the front of the car behind the bumper & attached to the front of the radiator. It has 2 wires & a 3rd wire that goes to the horn. Since it fell off the horn cable got ripped sad. . Any idea what this is?

temp sensor?

Yes, a picture would save a lot of time....But my "guess" would be the outside air temp sensor
