Your pictures came through just fine but I am not that familiar with the layout of this engine. Like all vacuum diagrams in a service manual, the actual physical layout of the components in a 3D world of reality are expressed on a 2D page. However, locating the components and tracing the hoses from end to end is fairly straight forward and should align with the vacuum diagram. Since I cannot see every vacuum component and port in your pictures and you are referring to component names that are not used in the service manual, I cannot be of much further help. There is no such thing as an altitude valve or an ab valve described in this manual. I can only suggest that you try to identify every component in the vacuum diagram, locate it on the engine, and trace the hoses from end to end. There is one vacuum hose and component not shown in the diagram. That would be the vacuum controller on the distributor. The vacuum diagram is on the 9th page of this publication, not the 10th as I previously said. >>> https://www.nicoclub.com/service-manual ... Manual.pdf

Maybe. Just maybe these links to Nissan Parts Deal may help. That old Nissan service manual shows nothing of what you are looking for but this link shows a rough image of the emissions control piping with the altitude device and the hose end you are holding in one of your pictures which routes up to and under where the air filter would be. >>> https://www.nissanpartsdeal.com/parts-l ... er=(2=Z22)
In this next rough image of the secondary air system, the AB valve is shown with a hose that also routes to the underside of the air filter. >>> https://www.nissanpartsdeal.com/parts-l ... er=(2=Z22)
