Replacing new heater hoses on 68 Imperial.

I am running new heater hoses on 1968 Imperial. when I bought the car, it had no motor or transmission and was a/c equipped.
Now that I put a new motor into the Imperial, I need to hook up new heater hoses & bypass a/c at the firewall.
Is there a “in” & “out” coming from heater core, at the firewall? Also, is there a “in” & “out” port, at the water pump? Engine is a 76 Chrysler 470 Stroker that I put into the car.
Need “in’s” & “out’s”
