These are GM modules. You can find excellent info on the Megasquirt site. I use the 8-pin module (85-95 V-8 trucks). It was probably the last revision before GM changed to distributor-less (coil-packs, etc). Main advantages: connectors are sealed, integral cable to coil, tach output wire, and spark advance can be commanded by a computer, and easy to source.
Nothing equivalent in Mopar world since they integrated the ECU inside the "engine computer" in the early 1980's, beginning with the notorious "lean burn" box which was a noble effort but gave problems.
