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. Intallation 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.
