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!
