Why waste extra cash on other vendor’s booster kits when it can be done at a much lower cost! Besides, who really needs brighter headlights and seat heaters that warm up faster when your car can be floored! All you need to do is install a 1 amp diode in the orange 12 volt reference wire and your systems voltage will raise by ½ a volt. Cut the orange wire and install the diode in a series with the stripe facing the alternator, or if you want a plug in unit, check out our Alt voltage booster kit.
*This is compatible and works very well with our alternator rewire. The alt rewire does something different, while this mod raises the voltage that the alternator actually puts out. The rewire kit delivers that efficiently and without the resistance losses in the factory wire.
