Default Vaccum line question

I am a first time Corvette owner and new to CF. I have looked for an answer to this without luck, so I was hoping someone could help. I found a loose vaccum line on my 79 and can't find where it goes. I dont know if I knocked it loose or if it was that wy when I got it about 3 monts ago. It is a vaery small plastic line that crosses to the passenger side from the driver side near the firewall. The pasenger side is the loose end. I am attempting to attach soem photos for clarification. I hope that maybe someone can look at theirs and easily identify the location.

I got rid of 95% of the vacuum-line-spaghetti under my hood so I can't help you, but from reading this forum I know there's a small vac hose that runs to something on the air-conditioning stuff on the passenger side (turns off A/C at full throttle or something??) but I am pretty sure it's small and white.

So I don't know the answer but here's TTT for you.

It is really hard to see where that line is connected...is it connected to that small grey disk below the cruise control diaphram? Can you tell us what it is connected with?

If you want to see yourself then pick up a Chilton's Repair Manual and look at page 4-42 which shows several vacuum routing diargrams for a 79.

That should be the vacumn feed for the interior of car---there should be another one that size coming from firewall and going to water shutoff valve under rt.fender

If the vacuum line is very small then it feeds your heater/AC control.
