4-pin wiring harness?

Tell you guys 'whut.' First Mopar breakerless was stripped off a car in about 1973, which I promptly adapted to my car. I don't remember what was wrong, maybe the kid wanted an Accel or Mallory

Anyhow, I've had a few since then, and in all the years from about 73 to present, I doubt I've replaced more than 1 or 2 ballast resistors. Might have been because one broke from cold water (in my old Landcruiser, had a 360, 340, 318 over the years!!)

Having said that I know use HEI. Mostly, because since they are more popular, they are more available, and the "modern" Mopar boxes may have a quality problem
