High-Quality Injector Connector Kit with Pigtails

If you’ve ever tracked down an injector trouble code on your Duramax—especially one that just won’t go away—you might’ve found the issue wasn’t the injector at all. A worn or failing connector can cause the same symptoms, and that’s exactly where the Fleece Replacement Fuel Injector Connector 4-Pack comes in. Whether you’re doing a full injector swap or just cleaning up a rough-running truck, this kit gives you the peace of mind that comes with brand-new, high-quality connections. This set includes four replacement connectors, each with a 4.5-inch pigtail, making it ideal for partial repairs or when you’ve got just a few that need attention. Over time, these connectors can develop resistance from heat and vibration, leading to poor injector performance or persistent codes like P0201 through P0208. Replacing them early helps avoid misfires, erratic idle, or worse—an injector circuit failure that leaves you sidelined.

High-Quality Construction & Design

Each pigtail is produced in-house by Fleece, using fully automated wire cutting and terminal crimping to ensure consistency and factory-quality fitment. These aren’t cut-and-splice parts you’re piecing together on the fly—they’re purpose-built and ready to install. The included heat-sealable butt connectors make the job quick and clean, sealing out moisture and preventing corrosion from creeping in later. Compatible with 2011–2016 LML, 2017–2024 L5P, and even the 2019–2025 LM2 and LZ0 3.0L Duramax platforms, this kit covers a wide range of applications.
