Correct Heater Hose Installation

I have a 318 poly with air conditioning and need the correct installation of the heater hoses. I have both a 66 Plymouth Repair Manual and a 66 Dodge Repair Manual. The Dodge Repair Manual says the water pump hose goes to the passenger side heater core pipe and the hose from the intake goes to the drivers side heater control valve pipe. A jumper hose connects the passenger side heater control valve pipe and the driver side heater core pipe. The Plymouth Repair Manual illustrates the complete opposite.

Does anyone know the correct installation or doesn't it matter one way or the other.

I never hesitated with that always just plug it wherever on any car
