All Chevy & GMC Truck Custom Forward Lamp Wiring Harnesses

These harnesses are custom modified by the manufacturer to allow the use of a later model "SI" series alternator. This allows for a clean install with no splicing required. Make sure to order the correct part for the side of vehicle that your alternator is mounted on.
