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 (QG18DE with tachometer), or 17 (QR25DE) for the speedometer
- from terminal 1 (with QG18DE), or terminal + (with QR25DE) of the vehicle speed sensor.

The speedometer converts the voltage into the vehicle speed displayed.
