Bill,
Got new temp sensor with "nail head." Installed it and pluged green wire on. But now the gauge in the speedo is not working. Checked wire diagram and pink goes to ignition wire and green goes to the sensor. If you were to turn and look at the back of the speedo, of the two connections on the temp gauge the green goes to the right and the pink to the left. All hardware is new..Any ideas would be great! Thanks! Jon
