Message The speed signal from the speed sensor to the speedometer, which then converts the signal and sends it to the ECU.

The signal that goes from the speedo to the ECU is yellow/green on the back of the cluster and at the ecu pin 53.

I can't recall the color of the wire from the speed sensor to the speedo, but I think its white.
