Man, that sounds confusing. There is only two wires going to the stock
coil, a negative and a positive. The positive is coming from the ignition,
a 12-volt switched connection and the negative goes to the distributor. the
distributor, as it turns, makes a complete circuit as it hits each cylinder
causing a 12-volt current to the coil. The coil steps that up sends the
28000-45000 volts back through the coil secondary to the distributor which
sends the spark to the appropriate cylinder based on rotor position. It
could be that the PCM also knows, based on the coil negative wire, when to
fire the injectors but what does that have to do with bolt-on replacement
coils? I use the MSD Blaster SS Coil. The same wires that would have gone
to my stock coil go to the MSD coil. I would imagine the same happens for
the Accel coils.

Received this from MSD ignition. Most of you guys out there use Accel
coils. Is the Accel coil a direct bolt in, Part # 140021 ? What is MSD
and Jacobs referring to when they say they don't make bolt on performance
coils because the stock coils also triggers the fuel injection. Does the
Accel coil trigger the fuel injection like the Dodge stock coil?
Thanx
