Product Description
Michigan Motorsports Glow Plug & Injector Harness
Fits 1997–2003 Ford 7.3L Powerstroke | Valve Cover External Connector Repair Harness
This Michigan Motorsports Glow Plug & Injector Harness is designed to repair one of the most common electrical failures found in the 1997–2003 Ford 7.3L Powerstroke. The factory external valve cover connector often melts due to the high current load required by both the glow plugs and injectors. This harness replaces the damaged connector on the outside of the valve cover—saving you significant cost and labor compared to replacing the entire engine wiring harness. Ideal for preventative maintenance or restoring proper function after connector failure.
Key Features
- Direct Repair Solution: Replaces the external valve cover connector that commonly melts or fails due to glow plug and injector current load on the 7.3L Powerstroke engine.
- Cost-Effective Alternative: Eliminates the need to purchase a full engine wiring harness—repair only the failed connector section.
- Recommended Preventative Replacement: Often installed alongside a new valve cover gasket and internal under-valve-cover harnesses to prevent repeat failure caused by heat or oil saturation.
- OEM-Quality Fit: Designed specifically for mid-1997 through 2003 7.3L Powerstroke engines that use a single electrical connector per valve cover.
- Durability & Reliability: Built to withstand harsh engine bay conditions—heat, oil, and vibration—restoring proper glow plug and injector operation.
Key Fitments
- Engines: Ford 7.3L Powerstroke Diesel (mid-1997–2003).
- Platforms: Fits 7.3L-equipped Ford F-Series trucks and E-Series vans using a single electrical connector per valve cover.
- Notes: If your 1997 model has two electrical connectors per valve cover, this is not the correct kit—verify before purchasing.
