HVAC Vacuum Line Mess

So I finally got my z running and was trying to figure out why I would only get air through the defrost and I looked at the vacuum actuators and lines and looks like whoever was down there last made a mess of the lines and left the disconnected and I found a piece lying on the floor as well.

I tried looking at diagrams but it isn’t doing much for me so if anyone can help me figure out which lines go where and where the little piece I found goes please do!!! I don’t want to pull the whole heater assembly out I just want to see if I can get the lines in order.

Also when I look at the diagram there is 5 valves on the drivers side and my car has 6, I’m so confused lol
