Could someone tell me what the different vacuum ports on my '85 IP do? I pulled all the vacuum stuff out and want to start from scratch and keep it simple. I understand the ALDA, but why the two connections on it? I can eliminate one, right? Which is the shutoff? I have a diagram, but it doesn't show everything and it certainly doesn't tell me what I can remove.

That is right. A and B can be combined into 1 port.

A makes a handy place to pull boost signal for gauges IF you have no leaks. Otherwise it is a REALLY bad place to leak...

If you leak to the ALDA you will lose fuel.

That's what I thought, but "REALLY bad" made me think something worse would happen. Like mechanic damage or something.
