ok

what you need to do now the modine is removed is have a pipe that goes from the back of the head to the heater matrix

on the water pump its as mentioned the one that goes to heater has a metal pipe that runs along the manifold obviously joins each end with rubber hoses

the one from the header tank depending on 2wd or 4wd has ametal pipe that bolts to the rad so from the bottom of this pipe goes to water pump as pictured then from header tank into metal pipe
