HEI in Mopar ECU casing

Coming in way late to the game. My orange box is bad. Going to replace it with a cheapy from O'Reilly just to drive and looking into this. @TrailBeast are you still running this? It looks like it's not that hard to do, just wire the 4 pins on the HEI unit to the corresponding 4 pins in the Mopar box, right? I replaced my coil with one from Rev N Nator (originally planned on going that route). If I do HEI, can their coil be used or do I have to do something else?
