The gauge sensor only has one wire. The two wire sensor is the temp 2
sensor for the ECU and idle controller. There is no polarity issue. The
connector is the same as the fuel injectors. Any good auto parts store
will have the repair pigtails for GM injectors.

Subject: are sensor wires polarity specific?

I replaced my water temp sensor (for dash gauge) and the connector was
so
corroded that I just put spades right on the wires to connect to the
sensor.
I'm curious if they have a polarity to them as my gauge went from
reading
50% for normal driving conditions to 75% for normal driving conditions.
Or
is this just the temperamental nature of the sensitive system?

The LED doesn't flash hot but I'm concerned once summer comes that the
gauge
will be sitting on 90% and not giving a very accurate indication of the
temp.
