PCM MODULE

General Information

Made for OEM integration on PCM controlled charging systems, our module can either be programmed to a set voltage or allow for adjustable voltage while maintaining battery light function. It also allows the retrofit of PCM regulators on older cars to dial in on the exact desired voltage. Designed for in-cabin or under-hood applications, the US Alternators PCM module is an easy install solution for most Ford, GM, Chevrolet, Buick, Cadillac, and Lincoln vehicles. Modules for most Honda, Toyota, Mazda, Infiniti, Lexus, Mitsubishi, Nissan, Scion, and Subaru vehicles will be released soon.
