One wire sensor on top of the upper coolant hose stub. At least on MC engines it is a variable resistance sensor which should read about 1000ohms with engine cold and about 100ohms when hot. My Haynes shows it is an on/off switch, I understand it was like that on older engine types. >The >only thing alike is a four wire electronic switch under the upper radiator >hose, but it is reffered to as some thermoprotection of the wastegate. It is the sender for the temp gauge and also provides "engine cold" and "overheat" signals for A/C programmer, ECU and auto-check unit.
