I have the three vaccume hoses that all go to the same thing then plug intoq the transfer case but there's one vaccum line that comes of the t case And y s off and it's just hanging down and I'm not sure where it goes any help or a vaccum diagram would be nice!!!!!

That is the vent line.

 

So where does it go. And there is also a spot beside the brake booster where the vaccum lines co e together and there's one missing I'll try to get some pics up

 

The vent line goes nowhere IT just vents air into the Tcase and Vents air out from the vacuum system when you disengage the 4x4.
