It does have 4x4 pretty sure it goes down and runs along side the vacuum lines for the 4x4. It looks like it goes some where around the brake master cylinder. 4x4 engages and disengages properly as far I can tell. Vehicle runs fine so I'm lost. I've been finding vacuum leak after vacuum leak with this thing.

I know there's a front axle vent line that secures up there around the master cylinder lines, but it usually has a different end on it. Zip tie it to a secure spot away from the exhaust manifold.
Looks like somebody broke yours off. It didn't attach to anything, it's just an open ended vent line. I tell you what. Those mechanic's smoke test machines are worth their weight in gold when you're trying to find vacuum leaks. They are real time savers.
