Dave0430 is correct in where the MAP connection has to be. To use a sensor in the plenum area, it would have to be a mass air flow sensor, and probably before the carburetor, or ITB if fitted. More challenging install.
Difficult at times to use the correct wording when trying to explain the issue. Being the author is harder than being the editor.
If there is an issue with how I describe what is being discussed in a post, let me know and I will correct it. Dave0430's short post on where you have to connect the MAP sensor to get engine manifold vacuum was what I wanted to mention, but could find the words at the time.
Cheers
