EA-81 AI, can I leave it unhooked?

We're putting the engine back in our '85 hatch, and I've ran into a little glitch. It seems I took what I believe was the AI control valve off of this car at one time and used it on another one. Rather than find another valve, can I just hook the vacuum lines directly to a vacuum source so the AI is working all the time, or would I be better off just leaving the AI unhooked? Is it better to have the AI working all the time, or not at all? That is the question. Thanks.

 

PS: Emissions testing isn't done on a car this old in NYS.
