Dorman 684-027 Parking Aid Sensor Compatible with Select Mercury Models

An assistance feature for accident prevention, the Parking Aid Sensor uses advanced sonar technology to alert you when you maneuver too close to hazards that are poorly visible. Dorman's sensor restores the parking alert system to original performance. The sensor includes a seal to prevent moisture from entering the unit, one of the most common causes of failure. Plus, it comes with matching connectors and fully compatible electronics, making installation simple and convenient.
