JEGS 1-Wire Alternator means just that… simply connect one wire from the alternator to the battery, and you’re done.
For 1971-1986 GM applications, replace the stock 63-amp alternator with a JEGS high-output Alternator that has an internal voltage regulator and fan to keep internal components cool.
