P101-L Voltage Boost Harness For GM 4 Pin Regulators For A 1 Volt Increase For Lithium Batteries Double magnet that efficiently increasesThis 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 simplified version of the H104 L which makes it great for secondary alternator setups for a cleaner look or engine swap applications. The yellow wire gets connected to an ignition switched 12V+ source to turn the alternator on and off with ignition and the blue wire with ring terminal gets connected to the
