Alternator Regulator Kit - Dodge Cummins Alternator

This external voltage regulator we offer is designed for Chrysler alternators, making it a better regulator than the one you may already have in your 1967-1988ish? Ford.  The Ford style regulator works, but erratic headlights are a common complaint when using them.  A pigtail connector is included in the kit, along with wiring instructions.  It is needed whenever the Dodge Cummins alternator is used on 1989-1998 12 valve engines, and also when using the 1998.5-2002 24 valve engines without the Dodge PCM.
