believe i read this somewhere but can not find.

Mike, I may have posted on TB the fact you could keep only black sensors in your drawer and replace blue ones with them.

The blue sensor has only one thermistor in it, but it is isolated from ground inside the sensor, then grounded externally where it is used. The black one has the same type of thermistor, but two of them, wired in common and grounded internally to the body of the sensor. Therefore the black one would work exactly as a blue one if used on a Volvo where its external ground would just be redundant.
