Michigan Motorsports UVC Valve Cover Harness | Fits 1994-Early 1997 Ford 7.3L Powerstroke | Under Valve-Cover Injector & Glow Plug Harness | Restores Proper Electrical Function | OEM-Style Wiring

Solve one of the most common 7.3L Powerstroke issues with the Michigan Motorsports UVC (Under-Valve-Cover) Valve Cover Harness. Designed for 1994–early 1997 Ford Powerstroke Diesel and International T444E engines, this harness replaces the factory-installed wiring that connects your injectors and glow plugs beneath the valve covers. A known failure point on early Powerstroke engines, the original harness often becomes brittle, leading to misfires, rough idle, or hard-starting conditions. Michigan Motorsports harnesses are built using high-temperature, oil-resistant insulation and OE-spec terminals to ensure long-term reliability. Whether you’re performing routine maintenance or repairing a failed connection, this UVC harness restores reliable electrical flow to the injectors and glow plugs—keeping your diesel starting strong and running smooth.
