    coolant temp sensor > is polarity important?

    Does it matter which way you connect the 2 wires to an engine's coolant temperature sensor? Does the thermistor inside the sensor have polarity? I do not know the pinouts on the car's temperature sensor and I do not want to risk damaging the car's computer. Thanks in advance.
