Where does this Hose go to?
 

I have this small hose under my hood (top right corner) that is loose and sucks air in when the engine is on. I don't have any idea where it goes I tried looking and I'm lost if anyone has a 2002 blazer like me and wants to tell me where theirs goes I would greatly appreciate it.

Hooks to a vacuum canister behind what your hand is on in the pic. Little bit of a pain to find, have fun LOL

Ok thanks man I found it, It plugs into something that's above the fender underneath that bracket on the right side of the picture. Wow that was hidden good.
