under hood vacuum lines with A/C

[drink2mny]

Here's the deal. the previous owner has vacuum lines every where.Running from the right side of the carb to a valve on the water hoses but split off to inside the cab. No vacuum ball on the heater core cover..and other lines going to the cowl vent..As soon as you start up the truck the cowl vent closes and the inside cab one opens.. he has the lines disconnected from the controls under the dash...

Does anyone have good pictures of what I need to do to fix this or have a vacumm line diagram that includes the a/c controls..

Thanks
