Description

The Fleece Performance Fan Extension Harness provides increased flexibility in your harness routing for your L5P Duramax's fan clutch. It mounts directly to the fan assembly and interfaces with both the fan and chassis harnesses. Fleece Performance utilizes a manufacturing process that incorporates fully automated wire cutting and terminal crimping. This product is specifically compatible with the 2017 through 2019 model years of the Chevy Silverado/GMC Sierra 2500/3500 equipped with the 6.6L L5P Duramax engine. The application notes also specify compatibility with cooling fan clutch part numbers 15-40577 and 84013368.
