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!

Holley EFI Coyote Smart Coils
Holley EFI Smart Coils are a bolt-in ignition upgrade for your late model HEMI or Coyote engine. Here's the difference over a stock coil: they produce more spark energy while consuming less power without sacrificing voltage output. This means you get hotter spark at the plug to burn the maximum amount of fuel in each cylinder while using less power from your electrical system. Smart Coils are available individually or in sets of 8. * For Coyote or Hemi combinations currently using Holley EFI or Terminator X, use Smart Coil Ignition Harnesses 558-312 and Coil Extension Harnesses 558-326 for a plug-and-play solution. * For new Holley EFI installations on Coyote engines, use with Holley EFI Coyote TI-VCT Main Harness for Smart Coils 558-122 and Smart Coil Ignition Harness 558-312 for a plug-and-play solution. Features: * Direct bolt-on to factory valve covers * Same wiring pinout as other IGN-1A coils for easy plug-in upgrades (Will not work with factory wiring) * More spark energy than any other smart coil on the market for maximum fuel burn during combustion sequence * Low current draw means less demand on the electrical and charging system * Built-in ignitor for compatibility with Holley EFI and many other aftermarket ECUs * Maximum operating voltage of 18 V—for compatibility with both 12 V and 16 V electrical systems found in many performance/race applications
