It’s basically a HEI module with a rev limiter in a nicely milled aluminum housing that is the same footprint as a Chrysler orange box with a 5 pin stock type connector. It’s 12 volt and needs a 12 volt 1.5 ohm coil.
You have to give the blue wire to the factory connector 12 volts all the time. Just need to bond ignition 1 and 2 ( blue and brown ) together or jump the ballast
