Where does the axle vent tube stow?

I recently got rear airbags installed and happened to look under the truck and notice the axle vent tube just hanging there. Where does it connect
to?

Looks like there is a retaining clip on it. I’m guessing it extends straight up and clips on the bed somewhere near the shock?? You probably just need to get it up out of the way of mud, etc. I’ll try and check but maybe someone here will know for sure sooner
