The signals for the operation of the speedometer, tachometer, temperature and fuel quantity are transmitted from the ECM using the Serial Data Bus. That would be the two purple wires in the cluster connector.

Hey so do you ju
The signals for the operation of the speedometer, tachometer, temperature and fuel quantity are transmitted from the ECM using the Serial Data Bus. That would be the two purple wires in the cluster connector.
So do you just tie the wire from the pcm to the purple wire going to the cluster?
