Where does the rubber tubing that comes out of the front diff from a 4×4 Jeep Grand Cherokee plug back in to?

I have a 98 Jeep Grand Cherokee, there's a loose rubber tube coming from my front diff, it looks like it should plug back into the engine somewhere but I can't find where. It's a prtty long tube, it was trialing on the ground so I've tied it up in the engine bay.

    it is the vent it should have a bracket it lays into above the hogs head, this does not go to the engine! it just has to be high enough to keep water out. like when you cross a creek!
