911 3.2 head temp sensor pin location
I removed tech connector for the head temp sensor as it needed to be replaced and forgot to note the pin location. Does anybody know if ground is the top or bottom pin?

The old one grounded through the sensor to the head. The two wire sensors don't, so it shouldn't matter.

Mine is a 2 pin connector. One being ground the other I assume is signal. Are you saying it doesn’t matter what pin goes to what?

Its a NTC, a kind of resistor. It has no polarity so it doesn't matter which way it is connected.

Pretty much like a light bulb. Works regardless of polarity.
