Southern Jeep back up North

So the PO of my YJ unhooked the heater core for some reason (probably because the heat stopped working at some point and never fixed it being that he lived in Florida)

So now I need to know how the heating system under the hood was originally hooked up. Right now I see the the inlet and outlet of the heater core sticking through the firewall hooked up to nothing. Where are the radiator/coolant lines supposed to run? Pics of a "stock" system would be great.

Thanks

The inlets and outlets are both different sizes, so when you hook them into the water pump area, they will be different sizes there too to get them back to factory directional coolant flow through the heater core.

can you describe the whole circuit. Radiator to water pump to etc.?

Or better yet, take a photo of how it is arranged in your engine.

Look for a smaller hose about an inch around making a loop passenger side of the engine. One should be right where the thermostat housing is. The other is coming from the water pump just beside the other.
