Correct heater hose routing to the Ranco heater valve on firewall 68'/69 B-body.

[GMP440]

What is the routing of the heater hoses from the water pump and engine manifold to the Ranco heater valve on the 68'/69' B-bodies with A/C?
Getting ready to put the heater valve on the firewall but want to be sure of the connections of the hoses.  Thanks.

Thank you for posting the diagram.  I saw that in my service manual too a few days ago.  The flow arrows are a little hard to see.
