Standard Ignition S-926 Oxygen Sensor Connector

Oxygen Sensor Connector Pigtail

Standard Ignition S-926 is a female oxygen sensor connector pigtail assembly built for electrical repair work where the original connector has failed, corroded, or lost terminal integrity. It uses high-grade materials to support strong conductivity and a secure connection for downstream oxygen sensor circuits and other listed applications.

Compatible With a wide range of GM vehicles, including Chevrolet Silverado, Cadillac Escalade, and GMC Sierra applications, this S-926 connector is used in multiple OE-style repair scenarios. Standard Ignition S-926 is designed for technicians who need a direct connector repair solution for 4-blade terminal systems.

Key Features

• Female connector design for OE-style electrical repair
• 4 blade terminals for 4-wire applications
• Pigtail assembly for connector replacement work
• Built with high-grade materials for conductivity and connection stability
• Used across downstream oxygen sensor and other listed vehicle circuits
• Standard Ignition S-926 cross-references 1P1677 and 57-5458 for the same application

Detailed Description

This oxygen sensor connector is part of Standard Ignition’s pigtail and socket program, developed to address common electrical failures with replacement connectors that restore proper terminal contact. The S-926 features a female connector body, male terminals, and four-wire construction, making it suitable for downstream oxygen sensor repair on many GM platforms. It is also listed for select body and electrical connector applications where the same 4-terminal female configuration is required.

• Corroded terminals causing intermittent sensor signal loss
• Worn terminal tension that creates poor electrical contact
• Connector damage from exhaust heat, vibration, or road exposure
• Failed OE pigtail repair on downstream sensor circuits

Installation Notes and Tips

Verify connector shape, terminal count, and wire configuration against the original part before installation. Match the vehicle application and sensor location listed in the fitment data, since this part is used in multiple downstream oxygen sensor and other 4-terminal female connector applications. Proper wire splicing, sealing, and terminal alignment are important for a reliable repair.
