Coolant Temp on LS1 Car What wire on a LS1 F Car does the Colant Temp Guage get it's signal from? I have it traced in the Harness from the Sensor, but which wire actually sends the Signal to the Guage..how is the Guage wired?

Depends on what year of pcm/harness you are running? 97/98 has a wire going from the sensor to the cluster. 99+up routes the signal from the sensor to the pcm and the pcm sends the info on the serial data line to the cluster.
