Keep Your LB7 Running Strong With A Simple Fix

If you're dealing with injector harness issues on your LB7 Duramax, there's no need to overthink it, this Fleece Outer Injector Harness Pigtail is the quick and reliable fix you've been looking for. Designed specifically for 2001–2004 Silverado and Sierra 2500HD and 3500HD trucks, this six-inch pigtail is a direct replacement for your factory outer injector connector. Whether you're tracking down a misfire or just refreshing an aging engine harness, swapping in a fresh connector can save you time, money, and headaches. Built with high-quality materials and precision crimping, it's made to last and built to OE standards. This pigtail connects to the GM inner injector harness (part number 97207227) and is essential if you're replacing or repairing your engine-side wiring. Since each engine uses four of these connectors, it’s a smart idea to replace them all at once if you're already doing injector work. It’s the kind of small upgrade that brings big reliability back to your truck.

Precision Built Connector For OE Fit And Function

The Fleece FPE-HAR-DMAX-LB7-INJ-PT is a high-quality outer injector harness pigtail built to meet the specific needs of 2001–2004 6.6L Duramax LB7 engines. Each pigtail measures six inches in length and is engineered to provide a precise fit with the GM 97207227 inner injector harness. Manufactured in-house by Fleece Performance, these connectors go through an automated wire cutting and terminal crimping process to ensure consistent quality and long-term reliability. This outer connector plays a critical role in maintaining electrical integrity between the main engine harness and the injector circuit. As injector issues are common in older LB7 platforms, having a dependable connector can prevent misfires, signal loss, and hard-start problems. This unit is sold individually, and four are required per engine for a full harness replacement. Designed with serviceability in mind, it’s an essential component for any LB7 injector job or harness repair. Built for durability and OE-level performance, it’s a small part that keeps your diesel running strong.
