Speedometer and Odometer

The instrument cluster contains a high-torque type electric speedometer. The electro-mechanical gauges plug individually into socket-type metal connectors in the cluster case.

ELECTRIC SPEEDOMETER
The electric speedometer drive replaces the mechanical drive for all C/K applications. Integrated circuits control the air core speedometer and stepper motor odometer.

The speedometer and the odometer receive a signal from the Vehicle Speed Sensor (VSS) calibrator module. This signal is generated from the vehicle speed sensor (VSS).

The Speedometer, grounded through the I/P Cluster ground circuit, receives its speed signal from either the VCM (Gas) or PCM (Diesel) through CKT 389 (DK GRN) which connects to the I/P Cluster at pin 14.
