None of the above is entirely correct.

What you need is to hook up to the vacuum post that DOES NOT (assuming everything is set up properly) have vacuum at idle. Once the throttle is opened slightly, the port will have vacuum. From there, the vacuum will be engine vacuum which changes depending on throttle position and engine load. The port you are pointing to looks to be the right place. You do not want straight manifold vacuum as you will have a hard time setting and keeping a consistent idle speed.
