Finishing touches can make a major difference when you are upgrading a charging system or detailing a classic GM engine bay. Clean routing and dependable connections not only enhance appearance but also support long term electrical reliability. For builders who want both function and a streamlined look at the alternator, the Holley Alternator Pigtail Harness delivers a purpose built solution.
Designed for GM alternators equipped with a 4 pin oval connector, this harness uses a Weather Pack style seal to help guard against moisture and debris. An in line 560 ohm, 1/2 watt resistor is integrated into the circuit, allowing the alternator to excite properly with or without a charge indicator light. The exciter lead is blacked out as it exits the plug to help it blend more discreetly into flex loom, and the 8 foot length provides generous reach for clean routing. The harness must be connected to a switched 12 volt source that remains active while the engine is running.
This pigtail configuration simplifies wiring while maintaining a neat, professional appearance. The built in resistor adds flexibility to your dash and warning light setup while supporting consistent alternator operation. Backed by a 1-Year Limited Warranty.
