What is this and where does it go?

Hi all,
2010 AC 4WD
Was peeking around tonight and found this little black box dangling near the trans cooler lines. It has two wires. A. What is it and B. Where does it go? To the right is the battery tray and obviously the radiator to the left. It has a plastic clip but I cannot find the whole for it to clip back in. Any ideas? Thanks!

 

I believe its the security beeper. You'll need someone to show you where it goes.
Try unlocking the doors to see if its the noise maker.

 

Thanks! I’ll find it a new home if that is what it is.

 

If it's indeed the beeper it goes on the radiator support in front of the battery.

 

Thank you!
