Angry 1997 f-150 radiator flush

i have a 1997 f150 with a 4.6.im trying to do a flush n fill ,and i can see the heater hoses coming out of the firewall,one on the left and one on the right.and i cant tell which one to install the flush tee on!both hoses go into the back left side of engine.not to the thermostat or water pump so i cant tell which one is the inlet hose.im using a prestone flush kit.
