Standard Ignition S3000 Oxygen Sensor Connector

Oxygen Sensor Connector for Ford and Lincoln

Standard Ignition S3000 is a weatherproof sealed oxygen sensor connector built for downstream and rear sensor service on select Ford and Lincoln applications. It uses a 4-wire, 18-gauge harness with a round female connector and male blade terminals for a direct electrical repair.

Use this connector when servicing downstream oxygen sensor wiring on vehicles such as the Ford Mustang, Ford Taurus, Ford Focus, Ford Escape, and Lincoln MKZ. The S3000 is a practical replacement for damaged, corroded, or heat-affected sensor connectors in emissions and engine management circuits.

Key Features

• Standard Ignition S3000 oxygen sensor connector
• Round female connector with male blade terminals
• 4-wire, 18 ga. harness construction
• Weatherproof sealed design for improved connection protection
• 13 in. harness length for repair routing
• Includes splice connectors for wire repair work
• Fits downstream sensor and rear sensor applications on select Ford and Lincoln vehicles

Detailed Description

The Standard Ignition S3000 is an oxygen sensor connector designed for repair of the sensor-side wiring interface on compatible Ford and Lincoln vehicles. Its 4-wire layout, sealed housing, and round connector shape support a secure electrical connection in exhaust-adjacent environments where heat and contamination can damage original connectors. This part number is commonly used on downstream sensor and rear sensor locations, including Ford Mustang, Ford Taurus, Ford Focus, Ford Fusion, Ford Escape, Ford Explorer, Transit Connect, F-150, and Lincoln MKZ applications. If you are replacing a worn connector on a Ford Mustang or Lincoln MKZ, S3000 provides the correct style of connector for the listed applications.

This part cross-references Standard Ignition S3000 applications with Monroe Shocks & Struts (e.g., CONB11464, EC3003) for the same application.

What It Helps Repair

• Broken or brittle oxygen sensor connector housings
• Corroded terminals causing intermittent sensor signals
• Heat-damaged wiring near the exhaust system
• Fault codes related to poor downstream oxygen sensor connection
• Harness damage at the rear or downstream sensor connector

Installation Notes and Tips

Match the connector style, terminal type, wire count, and sensor location before installation. Verify the vehicle uses a downstream or rear oxygen sensor connection listed for S3000, then splice the harness according to the vehicle wiring diagram and proper electrical repair practices. Confirm terminal engagement and sealing after installation to help maintain a stable connection.

Quality Assurance

Standard Ignition supplies electrical service parts for repair-focused applications, and the S3000 is built with a sealed connector design for dependable sensor wiring service on the listed Ford and Lincoln vehicles.
