We don't know what exact year of engine or intake manifold style you have. Generally, there should be a connection on the intake manifold near the thermostat housing for the heater hose TO the heater core.
I found this diagram for a TPI engines, and the hose connection seems to be directly under the throttle body.

The Throttle Body has coolant running through it so it doesn't freeze in winter conditions. It is unnecessary in summer and if you never drive in winter.
In a normal system, coolant OUT to heater core would be connection "2". If you want to bypass Throttle Body heating, connect hose to heater core to connection "1" (remove U-shape hose)
This guy has flow direction backwards when he explains it, but it shows the connections.
