Vacuum lines

In my 78 bronco I got 2 vacuum lines that go into the firewall and no clue what they do. Someone has tore out a lot of the vacuum lines and I'm trying to figure out what I need to hook back up

I dont remember for sure about these old trucks. I know newer models used vacuum on the switches for controlling the air blend doors. My old Bronco was not A/C so I cant look at it and tell you.
