Default Vacuum line

I got the vents issue that switches to defrost while accelerating. I was checking the vacuum lines and found a loose one just above the pcv valve but can't figure out where it goes. Anyone have any ideas?

From memory, that missing line is the one that goes to the reservoir.

The second pic shows the line I'm looking for going in behind the distributor cap. I can't seem to find it from above so I'll go under the truck in a day or 2. I don't know of it matters but mine is a 2wd... Thanks for the pics

the line in the second pic that goes to the rear, and down the firewall - i think that goes to the tcase for 4wd.

the line that 90* off to passenger side, goes over to a big wad with another split. those go to the reservoir (under the cowl on my 01) and into the firewall (i think) for the climate control.

I had to plug in a vac reservoir from a 97 blazer, the one under the cowl was cracked and leaking. it's just taped up and out of the way, solved the problem.
