Looking at going one wire. What do I omit?

[sprink88]

I am leaning towards the Ford G2 or G2 to keep it all Ford. But No matter what I use, Ford or GM one wire, what am I not using?

Do I still need the voltage regulator? Ballast resistor? Anything else?

I am going to a 390

You don't need a voltage regulator, the alternator doesn't need it. You need a ballast resistor depending on what ignition setup you use. I have a Pertronix distibutor/coil and they don't use a ballast resistor. I used a three wire alternator and a solid state voltage regulator on mine.

Thanks Lalessi1, I currently have a 3 wire off the 390, But looking to open up the engine bay and clean it up.

I am running an MSD 6A and an MSD 8594 http://www.summitracing.com/parts/MSD-8594

I have a pertronix igniter  on it and I had to use my ballast resistor

The stock coil requires the ballast resistor. I am using a Pertronix Flame Thrower coil that doesn't need one (per the instructions).

I'm using a Flame Thrower coil with my Pertronix without a ballast resister also..

I see. I am using a regular coil with my pertronix.

Since I am going with an MSD box and MSD dizzy, will I still need the ballast resistor?

Also going with a one wire alternator, I could get rid of voltage regulator, Right?

The instruction sheet should answer that, some electronic systems do not use the ballast some do.

Yes, both the GM and the Ford G2 & 3 have internal regulators.  Google the Ford and you will find a resonable plug and play wireing kit for both.

Thanks FBB, the box is used from a friend who needs a different one. Dizzy is new.

Yeah, I will google for a harness.
