P101-L Voltage boost harness for GM 4 pin regulators for a 1 volt increase for Lithium batteries
This voltage boost harness fits alternators with a GM 4 pin plug and is similar to our "plug and play" H104-L harness. The P101-L is the simplifie…
This harness may also be used WITHOUT THE BLUE WIRE CONNECTED as previously stated if you are currently running a regular battery but plan to upgrade later to a Lithium battery later in your build.
NOTE: This unit is NOT FOR USE ON STANDARD 12V AGM BATTERIES. This module will increase the charging voltage by 1.0 Volt, and will swell and damage AGM batteries. Please check with your Lithium battery manufacturer to verify the proper charging voltage before installing this module!
