Speedometer Head: Description and Operation

SPEEDOMETER
The combination meter receives a voltage signal from the vehicle speed sensor for the speedometer.

The voltage is supplied:
- to combination meter terminal 29 (without tachometer) or 47 (with tachometer) for the speedometer
- from terminal 1 of the vehicle speed sensor.

The speedometer converts the voltage into the vehicle speed displayed.
