1968 XR7 w/AC hose question

I’ve got things more or less under control in my project to get back on road.
Not going for concours, just serviceable and everything works.
Nearly ready to put engine in but can’t figure out where 1 hose will go.
It the one dangling on lower right.

That looks like the hose that fits pnto the bottom of the windshield washer bottle.

I might have guessed that but haven’t put it back yet.
