Planning Your Installation

How DriveRight VSS Works

DriveRight VSS obtains vehicle speed data from the vehicle’s built-in VSS (vehicle speed sensor) wire. When your car is moving, the speed sensor sends a signal to the console. The console uses this signal to calculate vehicle speed, distance traveled, and the rates of acceleration and deceleration.

Installation Overview

The procedures below and the wiring diagram on the next page provide an overview of DriveRight VSS installation.

1. Connect the harness cable to power, ground, and the VSS wire.

2. Connect the adapter cable to power, ground, and the digital inputs

(if using digital inputs).

3. Install the DriveRight console on or near the dashboard.

4. Finish the installation by powering the DriveRight, configuring the

VSS DIP switch settings, and testing the installation.

5. Calibrate the DriveRight speed readings. Calibration instructions

are located in the DriveRight 600

E User’s Guide.

CAUTION: Installing a DriveRight VSS can be hazardous to both the installer and to

the vehicle electrical system. This manual assumes you are aware of the inherent dangers of working in and around a vehicle and have a working understanding of electricity. If you are uneasy about installing DriveRight, please have a qualified professional do the installation. Davis specifically disclaims any liability for injury or loss resulting from the installation or use of DriveRight.

Planning Considerations

Before you begin, please review the planning considerations listed below and think through your installation. A little planning beforehand will save you time, frustration, and parts.

• Determine the best DriveRight console mounting location — Knowing the console mounting location will help you decide where to connect and route the harness cable and the digital inputs.
