VACUUM ROUTE B
I have these two identical pages that the local Mazda dealer printed out for me. The problem is I cannot figure out where these hoses go when they dissapear up under the intake manifold, carb, and air cleaner housing, etc. The hoses were either cut, or just broken off, with no thought to the resulting mess.
I read your question of >>" tried to decipher the microscopic routing schematics in my Haynes manual, impossible. I need large diagrams and/or photos of proper layout."<<
Not sure how you can be helped further, as Mazda shows on the diagram the colors & routing. There isn't any other "specific" Routing diagrams that show each connection at the Intake.I can enlarge the diagram like below & this can get you to most components, but you may need to find another Truck (salvage yard, used car lot, etc) & get a first hand look, because even a Technician that has worked many years on these could not pinpoint each Hose connection without consulting the Diagram
