Welcome to GneVibe! What were you doing in there to notice it was disconnected?

It has to go on the back of the HVAC controls, probably behind the one that controls where the air comes out (vent/floor/defrost)
I'd take a picture of it on mine, but it's back in behind, and even if I just pull the radio to see back there, I might not be able to get a good picture. I'll look the next time I have the radio out, but hopefully some one else will post a pic before I can get around to it. It is something you can leave off with little to no effect, especially now that the weather should be getting warmer
I leave mine disconnected all the time. I almost never use recirc, and can remember to turn it off it I happened to have used recirc and later need a quicker defrost, don't need the car to do that automatically. I disconnected mine on the back of the recirc switch though.
