Harness Extension - O2 Sensor 05-19 Dodge

The BBK Performance Harness Extension - O2 Sensor for 05-19 Dodge vehicles solves a critical installation challenge faced by enthusiasts upgrading to high-performance exhaust systems or custom headers. When modifying your Dodge Challenger, Charger, or Chrysler 300C's intake or exhaust flow, factory oxygen sensor wiring often falls short of the new sensor location, requiring an extension harness to bridge the gap. This 12-inch extension harness connects your downstream oxygen sensor to the factory ECU connector, eliminating the need for risky splicing or fabrication that can introduce electrical noise and trigger check engine lights.

Built specifically for Mopar Gen III Hemi platforms, this harness extension maintains OEM-grade connector integrity and signal fidelity between your oxygen sensor and engine control module. The 12-inch length provides sufficient reach for common header and exhaust manifold swaps without excess slack, while the direct connector-to-connector design ensures clean signal transmission crucial for proper fuel trim and emission control. BBK Performance engineered this extension to withstand underhood heat cycling and vibration, protecting against corrosion and intermittent electrical faults that plague cheap alternatives.

Mechanics and DIY builders working on Dodge Challenger (2008-24), Dodge Charger (2006-24), and Chrysler 300C (2005-24) models benefit most from this harness when installing performance headers, manifold upgrades, or aftermarket exhaust systems that relocate the front oxygen sensor. The pair configuration allows you to address both upstream and downstream sensor locations simultaneously, essential for comprehensive exhaust modifications. Installation is straightforward—simply disconnect the factory harness at the oxygen sensor connector, route the extension to your new sensor location, and reconnect; no splicing, no tuning required to maintain stock emissions compliance.
