Temperature sender

This is the original temp sender from the engine. It is a thermistor or temperature resistor connected to the temp gauge on the dashboard. When the temp goes up the resistance goes down. I'm mounting it to the controller to monitor the temp from the drivers seat. The controller operates up to 90C (195F) and will shutdown at 100C (212F). This corresponds to a typical 195F thermostat in a car so the gauge should read about halfway when the controller gets hot.
