These harness solutions are drop replacements—no cutting or splicing--for failed factory harnesses causing the problem. Each one installs directly in-line with factory connections, allowing you to reroute the alternator connection along the top side of the engine, and avoiding the unprotected channel routing on the underside of the engine. Designed and produced in-house, Fleece's manufacturing process includes fully automated wire cutting and terminal crimping to ensure you get the highest quality replacement parts you need to get your truck back on the road quickly.
