I think the question that we need answered is...what kind of alternator do you want? You can buy an aftermarket one-wire type that doesn't require but the one heavy battery current wire to keep rewiring to a minimun or one that requires more wires You might visit www.powermastermotorsports.com and see what is offered. They are a little pricey but it will give you an idea which way to go.
