The Harness - Alternator Pigtail AD Style from HOLLEY is a vital wiring component for builders and mechanics working on custom engine builds. This pigtail harness connects your alternator's internal voltage regulator to your vehicle's electrical system, ensuring reliable integration with Holley charging systems and aftermarket alternators.
Designed in the AD connector style, this harness features an industry-standard pin configuration that guarantees proper voltage regulation and current flow. Its robust construction is engineered to withstand the heat and vibration typical in engine compartments, maintaining low-resistance connections to prevent voltage drop during high-amperage charging cycles.
Ideal for restomod projects, LS engine conversions, and carburetor-to-EFI transitions, this harness is perfect for any application requiring a factory-style alternator interface. With a weight of just 0.11 lbs and compact dimensions, it installs easily in engine bays with tight clearances.
