Technical Details and Features

The Delphi SS20103 ABS wheel speed sensor features a pin terminal type with two male terminals, ensuring reliable electrical contact. It uses a single female square-shaped connector, designed for easy and secure installation. This sensor is intended for rear axle positions, specifically rear left and rear right, depending on your vehicle's requirements.

Installation Notes and Tips

When installing the Delphi SS20103 sensor, ensure the correct rear position is selected (rear left or rear right) based on your vehicle's configuration. The sensor connects via a single female square connector to the vehicle's wiring harness, which is not included. Reuse existing mounting hardware or acquire compatible fasteners to secure the sensor properly. Follow the included instruction sheet carefully to avoid damage to the sensor or connector terminals during installation.
