Plumb it for the type of valve that you have. If it's not the original type that had the extra port for the power steering, yes you hook it up like the post you found.
What I was saying in my last post was to basically run the vacuum directly to the throttle body and see if it idles up. Bypassing the valve as a test.

Im gonna try as per picture and see what happens.
Ok update for those who plan on taking this project on. If you use diaphragm below then you will need to T off the throttle body port to the diaphragm and power steering. I had been scratching my head for a year trying to figure out why it wouldn't idle up sure enough this fixed it. I used 1/4 brass T
