www.madelectrical.com, I bought his CS12 rewire kit along with several other items. Mike spent about 45 mins. just B/Sing with me about my ideas when I ordered the stuff from him. He even threw in a couple of items for free.
Took me about 2 hrs to manufacture the harnesses and about 5 hrs to rewire the alternator and charging system. I also installed 40 amp headlight relays all where the external voltage regulator used to be. It's a sweeeeeet looking install, and works great....
