Upgrade your 1988-1992 Ford Mustang with BBK Performance's O2 sensor wire harness extensions. Designed specifically for long tube exhaust headers, these extensions facilitate a seamless connection when relocating O2 sensors that are no longer in factory positions. Crafted with OEM style factory connectors, these harnesses ensure a straightforward plug-in installation without the need for splicing or modifying your factory wiring harness, saving you time and effort during installation. Made in the USA, these harnesses are built to meet high standards of quality and durability, providing reliable performance over time.
These harnesses include locator tabs to ensure proper positioning and secure connections. Since factory connectors can vary, you may need to remove small directional tabs from the connector ends for a perfect fit. This pair of OEM-style extensions is essential for enthusiasts installing full-length headers and mid-pipes, helping to maintain the integrity of sensor signals and prevent check engine lights or performance issues. They are backed by BBK’s 1-year manufacturer warranty, with optional extended coverage available for added peace of mind.
Whether you're upgrading your exhaust system or replacing worn wiring, these harness extensions are a practical and reliable solution. Designed to fit a range of 1988-1992 Ford Mustangs, they provide a direct fit for easy installation. With their high-quality construction and factory-style connectors, BBK’s extensions deliver a professional-grade upgrade for your muscle car or truck, ensuring optimal sensor operation and engine performance.
