Re: where does it go??

I pretty sure that is your front differential vent line. The hose extends over to the core support and the top of the vent is just below the upper radiator hose.

It vents the front axle housing to the atmosphere.
Cars and some 2wd pickup trucks often have a vent cap pressed directly into the axle housing like this:

But in a 4x4 application, that can let water get inside so they typically have a section of hose and/or tubing to extend the vent cap up to a higher location.
As gmachinz said, the 4x4 front diff vent cap is typically secured to the core support. And the rear axle vent is often secured to a frame crossmember or bed floor cross sill.

Replacement vent caps are readily available (if yours is missing) and would be a good idea to keep dirt and/or insects out of the vent hose.

Check the line and where it goes. My line in that location is the vent for my fuel tank that goes to a charcoal canister on the fender
