Hey Robert, is there a light on the box to tell you if it's getting power? You most likely have it wired to a + and - for overall power and the wire from the ignition switch to turn it off and on. Did you end up putting a relay in to switch the box off and on? If so is that wired so it's actually giving you 12 volts switched? Seems you had this box before the efi install so the coil trigger and tach connections would all be the same? Too bad your 1300 miles away, sometimes a second set of eyes help.
