As far as i can see from searching on ( Fast shipping. Up to 40% off Honda, Yamaha, Kawasaki, Suzuki and Polaris OEM motorcycle parts and accessories. Deep reseller discounts.
), they have 3 different rectifier models. None of them specifically say anything about how many wires etc. The part numbers are: 32800-44D11, 32800-44D21, 32800-44D31. I'm not quite sure what the differences are but if anything you may want to just call and ask your local dealership this very question and see what they say. They should at least be able to tell you exactly which rectifier assembly you need.
