guessing game

That vacuum line on the passenger side is my bet. Peel the black outer hose back and see if its a white vacuum line. If it is, hook it back up, it just slides on the tip of that gold thing. (Its a part for your A/C btw)
From your picture it looks like its the vacuum line i was showing. The tip is identical and it the actual line disappears into the same area under the truck.
It's easy to figure out.. just see if that gold thing it runs to has something connected to it or not. If it doesnt, problem solved, if it does, maybe someone else will chime in..
