Does anyone have a detailed vacuum hose routing diagram for my 1977 Pontiac 400 engine. I have the emissions sticker, but I have a hard time telling which part is which on the diagram. I know there are some things not hooked up - for example, I have only one hose on the charcoal canister (the carb one is missing) and I have nothing hooked up to the thermal vacuum sensor (I think that's what it's called).

Is it auto or manual?

Is there any way you can repost that diagram, and maybe a diagram for the carb? I also need a engine wiring dia. I need to buy that cd...but I sort of need the diagrams now :? thanks for the help!
