Pictures of mystery hose

[Sarasota]

These pictures are of the top of my transfer case. I was under there the other day and noticed a hose hanging off the tranny and connected on the other end to the fitting in this picture. The mystery is where does the other end connect to? I felt all around (everywhere I could) up on top of the tranny and couldn't feel the other fitting. The end that came off had dry rotted.

if there was a hose it would go to the underbody somewhere with a white plastic cap.
