I've checked schematics and diagrams but I cannot figure out what this is. I was pulling my fast idle valve off, wrench slipped and I broke a piece off the plastic shroud and bent one of the slim metal pieces inside (it looks like a cotter pin?) Not bent bad, but I can't figure out what it is and if I actually did any damage. Sorry it's not outlined well, it's circled in blue, left middle of pic.

 

Radiator fan switch. Looks to be unplugged as well.
