Basic Wiring Kits - 6.0L Powerstroke & Cummins and LLY/L7 Duramax

    When purchasing/installing a new high output alternator, upgraded charge cables are a much-needed upgrade.  The factory wiring harnesses are designed specifically for the stock alternator’s output. When a high output alternator is put into the equation, the stock wiring can't effectively transfer the power that the new larger alternator creates.  

     By adding upgraded wiring, the vehicle’s charging system will keep the batteries, and of course the FICM and other electronic modules and accessories running at their peak without any difficulties of getting the power they need.
