adding a charging fault light

So what kind of alternator do 5.2/5.9 magnum mills use?

My '93 Cummins Ram? The ram is a pita because the regulator is in the pcm and they fail every year the royals don't win a world series.

They work essentially the same as a 70/ later Mopar, and in fact you can wire up a 70 / later Mopar regulator instead of the pcm.
