I have the electric speedo and now wile diagram. Speedo light works, oil/gen light works, but speed doesnt. Which wire(s) actuate the speedometer part of the speedo. Thanks
The speedometer signal comes from the sensor in the trans. The are three wires in the wiring harness for the speed sensor. Red is 12V+ to the sensor. Black is ground. White is the signal to the speedometer.
