MOPAR ECU Gold Box

As mentioned it is to be used with a special coil and ballast resistor.
The box works great. Only negative I can tell you is to buy extra ballast resistors.
They will unexpectedly burn out resulting in a no start condition.
If I had to buy an ignition system again I think I would just buy an Msd 6 or 6 digital.
Probably no better performance, but more reliable. Ymmv
