Standard Ignition S-912 Oxygen Sensor Connector

Oxygen Sensor Connector for GM Applications

Standard Ignition S-912 is an oxygen sensor connector pigtail assembly built for repair work on damaged, heat-affected, or corroded sensor wiring. It uses high-grade materials to support strong conductivity and a secure electrical connection on a wide range of Buick, Cadillac, Chevrolet, GMC, Pontiac, Saturn, and related GM vehicles.

With an 8-inch harness length, 4 blade-style female terminals, and a male connector gender, this Standard Ignition S-912 oxygen sensor connector is designed for direct wiring repair where the original connector has failed. It is a practical OE-style replacement for upstream and downstream oxygen sensor connector service on many 1995-2011 applications.

Key Features

• Standard Ignition S-912 oxygen sensor connector pigtail assembly
• 8-inch harness length for repair and splice-in service
• 4 blade-style female terminals for sensor wiring connections
• Male connector gender with 1 connector body
• Built with materials selected for conductivity and connection integrity
• Used across many GM passenger car, SUV, and truck applications

Detailed Description

Standard Ignition S-912 is engineered for technicians replacing a failed oxygen sensor connector rather than the entire harness. It is commonly used on vehicles such as the Buick Lucerne, Cadillac DTS, Chevrolet Silverado 1500, and GMC Yukon, with fitment spanning upstream and downstream sensor locations depending on the application. This part cross-references Dorman - TECHoice 645-668 for the same application.

Standard Ignition focuses on pigtails and sockets for electrical repair, and this connector reflects that approach with a repair-focused design intended to restore a stable signal path between the oxygen sensor and vehicle wiring. The S-912 part number is a useful match when diagnosing intermittent sensor readings, connector damage, or wiring deterioration near the exhaust system.

What This Part Helps Fix

• Broken or brittle oxygen sensor connector housings
• Corroded or heat-damaged sensor terminals
• Intermittent oxygen sensor signal loss
• Wiring repairs after exhaust or underbody damage
• Connector mismatch during sensor harness restoration

Installation Notes and Tips

Verify connector style, terminal count, and sensor position before installation. This S-912 uses a 4-terminal blade configuration, so match the vehicle side and sensor side carefully before splicing. For best results, inspect nearby wiring for heat damage, clean any corrosion from the repair area, and confirm the upstream or downstream sensor location listed for your specific Buick, Cadillac, Chevrolet, GMC, Pontiac, or Saturn application.

Because fitment varies by year, model, emissions package, and sensor position, confirm the exact application against the vehicle listing before installation. The S-912 is commonly selected for GM oxygen sensor connector repair on vehicles such as the Chevrolet Malibu, Pontiac Grand Prix, and Cadillac Escalade.

Quality Assurance

Standard Ignition builds this connector using high-grade materials and decades of electrical component development focused on technician repair needs. The design is intended to address common connector failure points found in original equipment wiring.
