The Abbott ERA receives the speed signal directly from your SN95 Vehicle Speed Sensor (VSS) and allows you to accurately calibrate the speed signal sent to your instrument cluster. Installation is straightforward, requiring only four connections: power, ground, and two taps into the speed sensor wiring. Once installed, simply mount the control box inside the vehicle.

Calibration is quick and easy using the built-in DIP switches. Set the switches according to the Abbott ERA calibration chart or calculator, and your speedometer will be accurately corrected and ready to go.
