1996–1997 Ford 7.3L Powerstroke Engine Wiring Harness F7TZ‑9A451‑CA

Keep your 7.3L Powerstroke running reliably with this OE‑style replacement engine wiring harness engineered as a direct substitute for Ford part number F7TZ‑9A451‑CA. Designed specifically for 1996–1997 Ford F‑250 and F‑350 trucks equipped with the 7.3L diesel, it replaces the aging factory harness that often suffers from brittle insulation, chafed sections, and corroded terminals after decades of heat and vibration.​

Each connector is pre‑terminated and laid out to follow factory routing, so it plugs directly into the original sensors, injectors, and engine components without any cutting or splicing. This makes it ideal for fixing intermittent no‑start conditions, random stalling, and mysterious driveability issues that trace back to wiring faults rather than hard parts. Whether you are maintaining a work truck, freshening up a low‑mile survivor, or finishing a full 7.3L restoration, this harness lets you refresh the engine wiring in one go instead of chasing individual circuits.​
