Hellcat coolant flow?

On a Hellcat engine the hoses for the heater core are both at the rear of the engine. Which side is inlet and which is outlet for the correct flow

Nobody knows? There are two pipes sticking straight up behind the supercharger that go to the heater core. Not like other engines that have a hose to the block and another to the water pump. The reason I need to know is I am using a Vintage Air unit and it has a heater control valve that has to have coolant flowing in a certain direction to work.

I have no idea personally but would a factory service manual help?
