ranger 3.0 v6 1999

i have a vacuum line that fell off my truck and i cant seem to find where it went and what the hell its for but i know that its a yellow/orange in color line with 2 angle boots on the end for it...anybody have a clue as to where it goes?? cant find it in a vacuum diagram...help please

does it make the motor idle higher? it could be an a/c vacuum line.

It goes to a ball looking canister in the passenger side fender well I don't know what it does but it's there

i have a gray and black line in that ball shaped cannister...it doesnt effect the motor from what i hear...it was on the ground after i put my new frame under the truck and i dont wanna throw it away even if it runs fine

the vacuum ball is part of hte a/c. lemme do some more research on it tonite.

im thinking its something from under the top manifold that holds the throttle body...because my buddy owned it before me and he removed the top manifold to clean it all out becausehe hit a mudpatch and it went right into the air filter and the throttle body got messed up.....its not effecting how it runs to what i have noticed but its something that bugs me so much that i have to find out...thanks for helpin me out james and i have looked through my haynes manual and its no help
