6.1 hemi 6013 msd

Cool .
What im am looing for is the best way to wire the msd into the factory engine compartment harness?
I have seen some guys use the ballast resistor and some not... should it stay or should it go?
I have purchased the constant voltage regulator part #P3690731
I have heard about the alternator as well ... looking for advise on it as well ?

Thanks in advance!
