Vacuum lines and heater…

Okay, need some serious help here. Got 3, 4, or 5 lines that are confusing me. They were labeled nicely, but the painters cut and/or removed, and/or lost labels, so now I'm just trying to piece it together by use of my photos. In the attachment 001 we have the vacuum reservoir. You will note two lines coming out of it. The top one goes to the engine vacuum. The bottom line is Mystery Number One. Where does it go? In attachments 002 and 003 you will note that the end of the line has this very distinctive metal rod inserted into it. No other line on my car has such a metal rod. I hope this provides you guys a valuable clue. I will post my other line mysteries shortly. Thanks. By the way, my shop manual isn't much help; the diagrams do not quite match up. My manual is usually much more helpful. Oh well. Oh, one more thing -- the car has cruise control. That little fact changes a lot, it seems.
