The hose that connects to the water pump tube goes through the upper firewall hole and connects to the upper heater core fitting;
The hose that connects to the back of the head goes to the rear heater control valve fitting;
The hose that connects to the front of the heater control valve goes through the lower firewall hole and connects to the lower heater core fitting.
Don't use plain "heater hose". There are very tight bends that will kink if you use generic "heater hose". You really should only use the hoses made specifically for that vehicle. They're pretty easy to find.
