1970 Chevrolet Pickup 4 Seasons Vacuum Hose Routing

I need help locating a vacuum hose diagram from the accumulator to the air conditioner/heater control panel. There are 3 ports labeled 1,2, & 3 on the controls, I have no idea where the vacuum lines go.

O'Reilly's should have a supply of all sizes of hoses. You will need to measure yours for the correct amount.
