radiator drain plug location

I've got a 96 sebring convertible here with the 2.5. The radiator really needs to be flushed. Problem is i cain't find the drain plug. I got a prestone flush kit and i need to find out which hose to put the (T) piece on. I know i need to put it the the hose running from water pump to the heater core but i don't know which one it is. Any help is appreciated.
