Dorman 904-476 Fuel Injection Harness

Dorman 904-476 Fuel Injector Harness

Dorman 904-476 is a replacement fuel injector harness built to match the original part’s fit and function for direct injection systems. It uses quality materials and fully insulated electrical connectors to help maintain reliable electrical contact and resist corrosion in the engine bay.

• OE-style replacement fuel injection harness for direct injection applications
• Supports pulse width modulation fuel injection metering
• Connects to 6 fuel injectors with 7 male connectors and 12 wires
• Standard replacement grade for repair and service work
• Black and gray connector design with insulated terminals
• 28-inch length and 17-gauge wire construction

Detailed Product Overview

This fuel injector wiring harness is built for vehicles that use direct injection and pulse width modulation metering, where stable electrical routing is critical to injector performance. Dorman 904-476 is a practical replacement for worn, damaged, or corroded injector harnesses on applications such as Ford F-250 and Ford F-350 diesel service work, where injector circuit integrity matters for consistent engine operation. This part cross-references Standard Ignition IFH1 for the same application.

What It Helps Fix

• Intermittent injector electrical connection
• Corrosion at insulated connector terminals
• Cracked, brittle, or heat-aged wiring
• Misfires or rough running caused by injector circuit faults
• Harness damage from vibration or engine-bay wear

Installation Notes and Tips

Verify connector style, wire count, and harness routing before installation. Match the harness to the vehicle’s direct injection layout and confirm the injector connector orientation on Ford F-250 and Ford F-350 applications. Inspect adjacent wiring, clips, and injector terminals for damage before connecting the replacement harness.

Quality Assurance

Built as a standard replacement part to restore original equipment fit and function. The insulated electrical connectors are designed to help reduce corrosion at the connection points and support dependable injector circuit performance.
