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!

Painless Performance offers alternator backfeed diode kits for race car switch panels. In some cases, the GM 10SI and 12SI alternators backfeed through the regulator excitation wire—not allowing the engine to be shut off with the ignition switch. This diode, heat shrink, and butt-splice replacement kit lets you stop the backfeeding by installing it inline on the ignition switched wire going to the regulator's pin #1.

MechMan indicator light harnesses prevent the "check battery" light from coming on in the dash. Offered individually as well as supplied with all MechMan hairpin alternators for a range of GM trucks and SUVs, they accept oval GM alternator plugs. The longer blue wire gets connected to an ignition switched 12 V+ source to turn the alternator on and off with ignition and prevent the indicator light from coming on. MechMan harnesses can also be modified and hardwired to ignition 12 V+ for engine swap applications where the stock alternator harness is not available.

MechMan S Series 6-phase alternators offer incredible output in a compact and durable package. The 240 amp models offer the best balance between peak output, and output at engine idle RPM; while the 320 amp models are all about max power and not designed to charge at low idle speeds. Both S Series alternators feature 12 diodes, twin rectifier plates, and outstanding airflow ensure long service life, even in severe conditions. These units come equipped with a smaller 1.75 in. diameter alternator pulley, and will require a slightly shorter drive belt to be installed for proper belt tension. Order the model recommended for your auto application.
