Adjustable 91102R external voltage regulator w/ 2 pin alternator harness combo.  This unit will work with most OEM and MechMan Chrysler units from 1999 - 2006, and will allow the user to adjust charging voltage anywhere from 13.8 to 19.0 volts.  Please compare the plug on your alternator to verify compatibility. Installation of this unit will leave the OEM alternator harness unplugged, which will result in the check battery light in the dash staying on all the time.

We highly recommend that only experienced users or those very familiar with external voltage regulators use or install this item. If not installed properly or poorly, this item can damage not only itself but other components in the electrical system. PROFESSIONAL USAGE AND INSTALLATION HIGHLY RECOMMENDED.
