Standard Ignition S3119 Oxygen Sensor Connector

Oxygen Sensor Connector for Mazda Applications

The Standard Ignition S3119 oxygen sensor connector is a direct-fit electrical connector for repairing damaged sensor wiring on select Mazda, Ford, Kia, and Mercury vehicles. It features a female square housing with a 4-blade terminal layout and 18-gauge wiring for a clean connection at the oxygen sensor circuit.

Use this connector when servicing Mazda Miata, Protege, 626, Millenia, MPV, and Protege5 applications that require a reliable replacement for a worn or broken oxygen sensor plug. The 17.5-inch harness length provides 440 mm of lead length for routing in the original harness path.

Key Features

Detailed Description

Standard Ignition S3119 is an oxygen sensor connector built for repairing the electrical connection at the O2 sensor on select import vehicles. The connector uses a female housing with male blade terminals and a 4-wire layout, making it suitable for applications that require a direct replacement connector rather than a universal splice solution. This part cross-references CONB10848 and EC3144 for the same application.

Compatible With Mazda Miata, Mazda Protege, Mazda 626, Mazda Millenia, Mazda MPV, and Mazda Protege5 fitments listed below, this connector supports common oxygen sensor harness repairs where the original plug has heat damage, corrosion, broken locking tabs, or terminal wear. The S3119 part number is also a useful reference when matching the correct connector style for Mazda oxygen sensor wiring service.

Installation Notes and Tips

Match the connector shape, terminal count, and wire gauge to the original oxygen sensor plug before installation. Verify the sensor location and notes for the vehicle, including upstream, downstream, left, or front applications where listed. Inspect the harness routing and connector lock before final assembly to confirm a secure electrical connection.

Quality Assurance

Standard Ignition supplies electrical replacement parts for service applications, and the S3119 is built to match the connector style used on the listed vehicles. Confirm fitment by year, make, model, and sensor position before installation.
