Every time you move your safety from "Safe" to "Play" you hear a click. It's this little guy snapping into the bottom of the detent hole in the selector. Besides that there isn't much to say. It's installed pointy side towards the safety selector otherwise you will not have a good connection and your safety lever won't stay put.
