Product Description
This little pigtail is a lifesaver.
GM alternators require an exciter wire with a 12V switched source, otherwise they won't charge. We hear from a lot of swappers who have this problem, particularly when swapping to a carbureted system.
This pigtail solves that issue and even allows for the use of a voltmeter if you wish. Simply plug this wire into your alternator and connect to a 12V ignition switched source. Your charging problems are over!
Features:
- Fits GM alternators with a 4 Pin oval connector
- Weather Pack style seal
- In-line resistor that allows but does not require a charge light
- 8 ft. length
