How Do You Interpret The Vacuum Hose Diagram For A 1987 Ford Ranger?

i am working on my truck and just need to run the vacuum hoses. i have a vacuum house routing diagram but i dont understand it. i also have the manual for the truck but it dosent help me at all. i am not sure how to interpret the diagram to actually run the hoses, I do not understand the abbreviations used on the diagram, therefore, running the hoses is a bit confusing. the only thing i can depict is the carburator. thanks for any help!
