Not sure if I should call it control. I have a 04 5.7 truck Hemi going in a 69 Bee. Decided to go holley HP efi it will do everything but control the alternator. I am also using an American Autowire harness witch wants you to use a single wire alternator. Options? Is there an Internally regulated Denso style alt that will work? I need as muck amperage as possible. Or is there a way to wire up the stock 04 to work without an external regulator? I really don't want a gm style alt on this. Any help is appreciated. Thanks
