Jim,

The top outlet is for later models. The heater should be connected to the bottom of the water pump at the hose, should be a tapped hole for this. Then on passenger side at the rear should be a tapped hole for the other fitting for the heater. Not sure it makes any difference which one goes to what on the heater, since it is in and out. But one of the fitting should have a fitting to turn off the water flow in the summer.

I can send a picture of the setup if you like.
