Important Fitment Note
This harness is compatible with all 2003-2007 6.0L Powerstroke applications. The harness is manufactured using the later Ford design, so when installed on some 2003-2004 engines, portions of the harness may have slightly different factory bends or routing than the original harness. This is completely normal and does not affect installation, fitment, or performance. All connectors are correct, and the harness installs directly into the factory locations without modification.
Common Symptoms of a Failed Injector Harness
- Rough idle
- Hard starting
- Intermittent injector operation
- Injector circuit DTCs
- Engine misfire
- Loss of power
- Injector contribution or balance faults
- No-start condition caused by injector circuit failure
- Chafed, brittle, or oil-contaminated wiring
Replaces OEM Part Numbers

Installation Notes
- Connects directly between the Fuel Injection Control Module (FICM) X1 & X2 connectors and all eight fuel injectors.
- No cutting, splicing, or wiring modifications required.
- Inspect injector connectors, FICM connectors, and retaining clips during installation.
- Always verify that wiring is routed away from sharp edges and excessive heat sources.
- Professional installation is recommended whenever injector or FICM service is being performed.
