Holley Alternator Pigtails
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!
