took off my intake cover and plenum to paint them tonight

99 4.6L f150

and i accidentally disconnected a vaccum line. Its the one that connects to the lower connector on the plenum right near the throttle body. the top one being the one with that mysterious box thing noone can figure out what its for. the hose is solid plastic and seems to go down somewhere underneath the intake towards the EGR stuff. i cant look anymore in the dark so im hoping you guys can give me some ideas so it dosent take me an hour in the freezing cold tomorrow to find where it goes.

thanks

 

after daylight the awnser was ovbious, it leads to the "fake" pcv valve on the drivers valve cover.
