Oh wait, I see now. One branch of the 5-way connector looks like it goes down to the pump. My bad. Not used to seeing it that way.

Let's establish a baseline. Click on the first link in this post - Vacuum Diagrams and do what you can to hook up the vacuum lines that way. It looks like most of the work will be right at the 5-way connector. If you want to simplify things for now, close off the branches of the 5-way connector that go towards the passenger side of the car.

[edit] The diagram doesn't show the split in the line into the center of the round blue thing/transmission vacuum amplifier/BFS (blue flying saucer) on the driver side fender. Keep that split in place for now.
