Default Optispark vaccum hose location?

Been trying to figure out where it gets plugged in and asked several mechanics with no help.

It was like like this when I bought the car a few months ago just laying on the manifold. :o

I thought it did I saw an engine at a junkyard and the hose was facing down toward the opti but couldnt see where then when I grabbed it to see where it was going it came right off.
