Give your vehicle the power source it needs with Holley alternator pigtails. These weatherproof plug and wire pigtails are designed for select Holley alternators or similar Delco AD-style alternators. They're fairly easy to install--just connect the yellow wire to switched voltage that is "on" when the key is in the run position. These pigtails have a resistor inline, so a charge indicator light is not required. However, if the vehicle has a charge indicator light, the yellow wire can be connected to it and the light will function. So, for high-amp, high-torque solutions for some of today's toughest applications, give Holley a go!

With performance engines pushing redlines up higher and higher, alternators are being forced beyond their design. Holley's premium alternators can tolerate 30 percent higher rpms than conventional models. The attention to cosmetic detail on these units is above and beyond what you would expect, too. The entire outside housing has been sculpted for a smooth silhouette that hides the ugly details we typically think of as alternators. If you drag race, autocross, or just hot rod your ride, be assured that Holley premium alternators won't fly apart on you. Features: * Available in natural, black, and polished finishes * Works with all Holley accessory brackets, as well as 4th generation F-body, most 1998 thru 2004 GM trucks, and many other applications * 150 amp output * Smaller and lighter than Holley high-amp alternators * Housings are smoothed to make polishing clean (no buffer cut marks trying to get in tight corners) * Rear cover is aluminum instead of typical black plastic * Ideal when size and clearance matter * Black and polished pulley covers are available on models that don't already include them * Designed for use with Holley alternator weatherproof pigtails (not included)

One of the challenges with a Gen III Hemi swap is alternator clearance. The Holley Gen III Hemi alternator with relocation kit is the solution. These kits come complete with everything you need to move the alternator to a more ideal location to provide additional clearance to the frame on the passenger side of the engine. The kits include the mounting bracket, pulley, alternator and hardware for installation. The alternator is smaller and more compact, further helping clearance issues, making them easy to wire. The steel relocation bracket is black powdercoated for extra rigidity and corrosion-resistance. Make your Gen III Hemi swap easy with one of these Holley kits.

The factory alternator on the 2020 and up Ford 7.3 L Godzilla engine is a bulky single or dual alternator design that is tough to package in an engine swap. The Holley Ford 7.3L Godzilla alternator kits provide a more compact solution for extra clearance and works with the factory timing cover, water pump, damper/crank pulley, and intake manifold. They also will work with after-market damper/crank pulley. The bracket and alternator are compact and lightweight, and the Holley alternator is easy to wire and does not require the factory ECU to function like the OE alternator. Holley includes the plug/pigtail, pulleys, and belt in a complete kit. Please note the included belt is for alternator-only applications, but the instructions specify the belt for other configurations. The bracket allows for any accessory configuration, and it works with or without the air conditioning compressor and with or without a power steering pump. Features and details: * Alternator kit and mounting bracket for Ford Godzilla 7.3-liter engine swaps * Great solution with everything needed to add an alternator to the Ford 7.3-liter crate engine * Eliminates bulky dual alternator system—factory setup on some heavy-duty trucks * Works with the factory timing cover, water pump, damper/crank pulley, and intake manifold—also works with after-market damper/crank pulley * Compact design with alternator pulled in tight to the engine for extra clearance under the hood * The mounting bracket is compatible with Holley alternator models: PN: 197-300, 197-301, 197-302, and 197-303 * Easy wiring of alternator and does not require factory ECU to excite alternator—wiring pigtail included * Choose from a complete kit with 105-amp Holley alternator (PN: 20-380), or bracket kit (PN: 97-409) * Natural as cast finish on the mounting bracket and alternator * Works with or without an air conditioning compressor * Works with or without a power steering pump * For alternator-only race setup, Holley bracket PN: 97-409 should be used with Holley premium alternator (PN: 197-302 or 197-303)—ideal for high rpm applications (alternator designed and tested for up to 30 percent higher rpm) * Ideal for use on Godzilla crate engines and engine swaps
