Oxygen sensor connector
A 4-Pin O2 Oxygen Sensor Pigtail Wiring Harness Connector, designed to interface the oxygen sensor with the vehicle's main engine wiring harness. Being an original OEM dismantled part, it offers high thermal resistance suitable for placement near the exhaust manifold. Equipped with internal silicone weather-seals to prevent water, oil, and dust ingress. Features a 4-wire configuration: 2 wires for the internal heater element, 1 signal wire, and 1 ground wire.
Workshop Tip: Always solder the wire joints and apply heat-shrink tubing to prevent resistance drops and corrosion over time
⚠️ Compatibility Note: Wire colors on the connector may vary depending on the production line and may not always match the photos or your vehicle's original wiring harness. Please rest assured this difference is strictly cosmetic and does not affect product quality, compatibility, or proper installation.
