I need 12v

Have you talked to Holley about this? I find it hard to believe that they would produce a fuel injection set up that requires special electrical requirements without including the necessary pieces in the kit or information in the instructions.

It probably works on a chev or Ford, from what I understand the ign 1/ign2 is a mopar thing. Anything with a 12v during both crank and run is what they are looking for.

Ah..........yes. If you put it ONLY in the EFI wire that would limit the current you need. I would measure it. Doesn't that system have a "full time" 12V and then an ignition trigger line? That trigger likely does not draw much. There are some diodes NAPA may have, but finding something they have and you want may be tough. I'd just get on line, even Egag, about a 5-10 amp rectifier at 25V PIV or more is enough.

If that is the case, you would want to hook the diode to coil+ (as if it was ignition switch and the other end ONLY to the EFI power trigger wire

Then leave the wire on the EFI side of the diode connected to IGN1

Yes, what I jumpered is the trigger wire. That runs to the ecu, which controls the relay supplying 12 straight from the batt. Found a 6a at a starter/alt rebuild shop. Will put that in the “jumper” wire, so that should stop current from bypassing the ballast resistor, which is what I understand you feel I need to do. That sound correct?
