The heater valve is in line in the heater hose from the top back of the 350 engine about half way to where it enters the firewall to connect to the heater core. The valve has a steel wire control cable connected to the top of the valve control lever. It has two hose connections, one in from the engine and one out to the firewall core entry point.
