vacuum line question

so we've installed the fmic, the sti injectors, utec, and started the car. car had a royally rough idle due to a vacuum line being disconnected. now that we've found the line, we dont know where it connects to. when looking at the engine bay from the front, it comes from behind the intake manifold, runs about 4-6 inches, and has a 90* bend at the end. its not long enough to reach the throttle body, and goes somewhere underneath the intake manifold. anybody got any clues?

If it's 1/2" or so in diameter it's the PCV line.

isn't that the hose for the blow off valve? since you don't have the top mount anymore, that means you don't have the blow off valve at that area anymore...right?
