The hot water out to the heater comes off the fitting on the intake manifold, just behind the thermostat. The upper water pump connection gets connected to the short 90 deg. hose exiting the thermostat housing. The lower water pump connection is the water return line from the heater. Depending on how you mount your alternator, you may have to use an elbow from the plumbing department so you don't kink the heater hose.
