101755 - 4 to 2 pin Voltage Regulator kit for GM

101755K This kit allows you to convert from a 4 Pin voltage regulator on the GM AD244 and AD230 Alternators to a 2 pin connector. The 2 pin connector was used on GM DR44 alternator from about 2005 & up. Converting from 4 pin to 2 pin type voltage regulator allows you to use the earlier AD series alternator (4 pin) in place of the later DR44 and Bosch alternator with 2 pin connector.
