MOTOKU O2 Sensor Extension Harness for Chrysler Dodge Jeep — 2×12" & 2×24" kit, OEM-style plug-and-play

MOTOKU Oxygen O2 Sensor Extension Harness is a plug-and-play cable kit that extends O2 sensor wiring for Chrysler, Dodge, and Jeep vehicles, supplied as two 12-inch and two 24-inch harnesses to simplify installation and relocation of sensors.

If you need extra wire length to reposition oxygen sensors, avoid strain on factory wiring, or accommodate engine swaps and exhaust modifications, this MOTOKU harness kit offers a straightforward solution. The set contains four extension leads—two at 12 inches and two at 24 inches—designed to mate with original equipment connectors used across many Chrysler, Dodge, and Jeep models. Built to help maintain reliable signal transmission, the harnesses let you route sensors more safely without cutting factory wires or splicing fragile connections.

How will this harness help when relocating an O2 sensor?

The MOTOKU extensions provide additional cable length so you can move a sensor to a new, safer location without stretching the original wiring. They preserve the factory connector ends and make reversing the modification simple.

• Includes two 12" and two 24" extension leads for flexible routing options.
• Maintains OEM-style connectors to ensure proper fit and polarity.
• Prevents tension on factory wires during engine or exhaust work.

Will these harnesses fit my Chrysler, Dodge, or Jeep model?

These extensions are made to be compatible with common O2 sensor connectors used on many Chrysler, Dodge, and Jeep vehicles. Confirm connector type and pin count on your vehicle before purchase to ensure a match.

• Designed for typical OE oxygen sensor plugs found across the brands.
• Works with both upstream and downstream sensor locations depending on fitment.
• Measure required length relative to engine bay layout before selecting placement.

What are the practical benefits during installation and maintenance?

Using an extension harness reduces the need to splice factory wiring, speeds up installation, and keeps diagnostics reversible. The harnesses also reduce the risk of wire damage from heat, movement, or aftermarket exhaust changes.

• Plug-and-play design cuts install time versus hard-wiring extensions.
• Reusable connectors make future maintenance easier and cleaner.
• Extra length offers better clearance from headers, manifolds, and hot components.

How durable and reliable are these extension leads?

The MOTOKU extensions are built with automotive-grade materials to withstand engine-bay conditions and to preserve sensor signals. While not a warranty substitute, they provide a robust, temporary or permanent wiring solution when used properly.

• Automotive-grade insulation resists heat and abrasion in most engine compartments.
• OEM-style terminals preserve electrical continuity and correct pin arrangement.
• Sold as a set of four to cover multiple sensor positions in one purchase.
