LIZAPUS O2 Oxygen Sensor Extension Harness Set - 4PCS (2x24" + 2x12") Plug-and-Play OEM-Style

LIZAPUS 4PCS O2 Oxygen Sensor Extension Harnesses provide plug-and-play cable extensions to relocate or lengthen your vehicle's oxygen sensor wiring without cutting or splicing.

These OEM-style extension harnesses are made to extend the reach of factory oxygen sensor connectors on many Dodge, Jeep, Chrysler, RAM and SRT models. Sold as a set of four, the kit contains two 24-inch and two 12-inch extensions so you can route sensors around aftermarket exhaust systems, repairs, or custom installations while preserving original connectors and vehicle electronics integrity.

How do these harnesses simplify O2 sensor relocation?

The extensions plug directly into the vehicle and the factory sensor harness, so no soldering or electrical cutting is required. That reduces installation time and preserves the vehicle's original wiring for easier future service.

• Direct plug-and-play connectors match factory pins and housings
• Two 24" and two 12" lengths for flexible routing choices
• Pre-tested and ready to install—no extra tools for wiring

Will these work with my Dodge, Jeep, or RAM model?

These extension harnesses are designed to be compatible with many Dodge, Jeep, Chrysler and RAM applications, including SRT and 1500/Charger families, when the stock oxygen sensor connector style matches. They extend only the wiring; they do not include oxygen sensors themselves.

• Intended for use with factory-type O2 sensor connectors on supported models
• Check connector shape and pin count against your vehicle before purchase
• Oxygen sensors are not included—extensions only lengthen the existing harness

What advantages do different cable lengths provide?

Having both 24-inch and 12-inch extensions in the set lets you choose the best routing for each sensor location. Longer runs help when moving sensors past aftermarket pipes or components, while shorter runs prevent excess slack in tight spaces.

• 24" extensions suit major rerouting around exhaust or chassis parts
• 12" extensions are ideal for minor adjustments and tidy installations
• Using the correct length reduces stress on connectors and prevents chafing

Who is this for? These LIZAPUS O2 sensor extension harnesses are aimed at mechanics, custom exhaust installers, and DIY enthusiasts who need to relocate or lengthen oxygen sensor wiring without altering factory connectors. If you’re replacing exhaust components, installing aftermarket headers or catalytic converters, or need additional slack for routing, this four-piece set offers tested, ready-to-install extensions to keep your original sensors and vehicle wiring intact.
