I need 12v

I have FiTech, but I can't imagine the Sniper being any more complicated. You just need a two wire MSD alternator(or MSD clone). All the timing etc is just simply punching in the numbers you want. Then you run her down the road. You don't like it, bump a number up or down while you are rolling, until you are happy. I would personally go that route before I spliced in diodes etc. Also the voltage drop is to protect the OE ignition, if you are running aftermarket, you can have it all full 12v

Sorry the issue is that HE IS RUNNING A MOPAR BREAKERLESS ignition WHICH MUST USE a ballast resistor.

Also you might want to correct your post. ???MSD alternator??? Whut?
