quick and easy

I bought this holley connector kit to use an LS style alternator on an older sbc. After frying an alternator due to not using a resistor this sloved the issue. Holley combined the correct connector and resistor making it simple. So for so good 14.3V.

Does what it’s supposed to

When you need a four prong plug for the exciter wire for your GM alternator here you go; having the resistor already built in. however I think Painless has a cheaper one that will work too

Holley - 197-400 - Holley LS Accessory Drive Kits

Makes sure you have a water resistant connection at the alternator and allows for proper installation for charging.
