Dorman Fuel Injection Harness Connector

Dorman Fuel Injection Harness Connectors: OE-Quality Replacements That Last

When a fuel injection harness connector fails — whether from heat fatigue, corrosion, or simple age — the result can be rough idling, misfires, or a no-start condition. Dorman has spent over a century in the automotive aftermarket engineering precise, vehicle-specific solutions, and their lineup of fuel injection harness connectors reflects that depth of expertise. Rather than forcing technicians and DIYers into an expensive full-harness replacement, Dorman offers targeted pigtail connectors and repair connectors that address the failed component directly.

The Conduct-Tite Product Line

Dorman markets its fuel injection harness connectors under the Conduct-Tite brand, backed by a team of product experts in the United States and more than a century of automotive experience. The Conduct-Tite lineup spans a wide range of injector connector styles, including 2-wire throttle body injector connectors and Lucas/Bosch fuel injector harness connectors with offset index — covering domestic and import fuel systems alike. For diesel applications, Dorman also offers glow plug and injector harness repair connectors , extending coverage beyond gasoline-only platforms.

Engineering Built for the Real World

What sets Dorman apart in this category is the attention to fitment and environmental durability. Each fuel injection harness connector is designed to match the appearance and function of the original hardware on specified applications. That means no splicing, no guesswork, and no adapter kits — just a clean, factory-style connection. Connectors are engineered with weatherproof terminals and a locking tab for a reliable quick-disconnect electrical connection.

For full harness assemblies, Dorman raises the bar even further. Harnesses feature fully insulated electrical connectors to prevent corrosion, are made with factory-style connectors for plug-and-play installation, and have undergone try-on, corrosion, and material testing to ensure a quality fit and long service life.

A Smarter Repair Strategy

One of Dorman's core philosophies in the fuel injection connector space is enabling component-level repair. Replacing only the damaged connector — rather than the entire assembly — saves money while still restoring OE-level reliability. This approach is particularly valuable on older vehicles where sourcing a complete OEM harness is difficult or cost-prohibitive. These connectors serve as an ideal solution for an original part that is missing or has failed due to fatigue.

Some of Dorman's solutions, like their OE FIX products, address problems you can't even get a fix for from original vehicle manufacturers. Whether you're a professional technician or a seasoned DIYer, Dorman's fuel injection harness connectors deliver the right combination of fitment precision, construction quality, and installation ease to get the job done right the first time.
