The engine coolant temperature (ECT) sensor is at the upper hose nozzle, it's also got a plug with 2 wires. That's for the fuel injection ECU to measure temperature.

Ok, before I replace the sensor / switch I jumpered the thermostat housing switch and with the key on, both fans came on. Then I jumpered the top hose water outlet switch and only the radiator fan came, this with the key OFF.

Question: if after replacing the switches the problem remains the same, would there be harm in jumpering the fans so they both come on every time the key is on?

I guess I wouldn't know how to answer that without seeing a wiring diagram for your year. They're not all the same. Besides, I'd probably want to make it work the way it was supposed to that year.
