Vacuum lines to no where.. What do they connect to?

[KLUTZ]

Among the cut wires and hoses not being where they were supposed to be, I have come across three, I believe vacuum tubes that I can't figure out where they go.
The first one goes to the canister area in the front driver side corner and has this on the end. It reaches near the rear of the engine bay:

The next two pictures.. The top left tube comes off just in front of the Dizzy and goes to the other side of the Dizzy but I have no idea where it connects. There is also (can't really be seen) another open tube, the same as the first one, on the firewall between the Fuel pump relay and the Dizzy, close to where the first one reaches. I tried to trace it but can't follow it. Hopefully the pictures will give an idea of what I'm talking about. I really hope my manual gets here this week..

Thanks again for the assistance..

Great. That is what I figured. After looking at the connector again, the back connector on the three way "Bulb" is broken off, that's why it didn't make sense to me. Can I buy that connector at any auto parts store or do I have to get it from GM?
