- The 4-pin regulator style alternator must be used for this to function properly.

2-Pin RVC Bypass Module For Factory 2005 and Newer GM Vehicles Mechman P103
This listing includes:
Designed for GM vehicles equipped with a 2-pin regulator and a RVC sensor (Regulated Voltage Control), this module simplifies installation by plugging directly into your vehicle's factory harness. By doing so, it resolves issues related to the check charging system code (battery light).
For optimal functionality, it is important to use a 4-pin regulator style alternator. Please note that this solution is not compatible with stock 2-pin style alternators.
This module is particularly popular among customers seeking to bypass the RVC system to run a stand-alone alternator. This modification results in a more stable voltage output compared to the factory setup, which can experience voltage fluctuations and lower charging voltages due to PCM control aimed at maximizing fuel economy.
It's important to note that this module is not compatible with factory alternators. For proper compatibility, a unit with single ignition switched turn-on is required. When purchasing an alternator, please specify the need for single wire turn-on in the order notes. If you already possess the correct alternator and require only the plug, the P101 harness is also necessary.
