2000 Mazda B4000 Heater hose diagram

Hi, I just replaced the 4 port heater valve on my truck w/ the 4 liter OHV engine and I forgot where the hoses from the waterpump go. Does the hose on the top of the pump go to the top port in the valve or vice versa? I wrote it down on heater core side so its ok there. Help would be much appreciated. Steve

As long as the ones going to the heater core are correct it's not going to make much if any difference.

Thanks for the response. Attached the top waterpump hose to the top hose on the valve and it works fine.
