Vacuum Diagram 200 1978

Hi, my first post. I need the vacuum hose diagram for my USA 1978 245 with CIS. It has two(yes two) hose connections at the distributor, Applying vacuum at one causes the timing to advance, and to the other causes it to retard. I do not know how to connect these to the various vacuum outlets at the intake manifold or the one way valve in the pollution control vacuum line connected from the intake manifold to the air cleaner.

Many thanks for your help. Jim Gordon
