It will be whichever hose comes from the water pump outlet (close to thermostat).
It is actually a good practice to reverse the flow through the heater core periodically to keep it flushed out. You just swap the two hoses right there where your arrows are pointing.
Are those up there in my post all the hoses I need/the correct ones?
