The Fleece Performance Fan Extension Harness fits the 2011-2014 Chevy Silverado 2500HD with the 6.6L LML Duramax and lets you repair a broken or damaged fan harness without replacing the entire fan assembly.

Install Difficulty: DIY Possible
Unplugs and replaces the factory fan harness at the fan assembly and chassis connector with hand tools; typically installs in 30-45 minutes with the fan shroud area accessible.

Product Overview

This replacement harness mounts to the fan assembly and connects the cooling fan to the chassis harness. It's a direct fix for damaged factory wiring that would otherwise force a full fan assembly swap.

Fleece builds the harness in-house using fully automated wire cutting and terminal crimping for OE-grade quality. Fits factory cooling fan clutch part numbers 15-40580, 15-40513, 84144840, 25838900, 1540513, 84166745, and 23134137.
