Description *External regulators can be built alongside alternators for plug and play operation. Alternators and external regulators are built to order, please allow 2-3 week build time and shipping.* 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. If your current alternator has a GM 2pin (2005 and up), this unit will NOT work as a direct plug in. Please contact us or use the RGA REQUEST form in the home page categories tab to request a modification to your current alternator for compatibility.
