A buddy is installing a Holley Sniper EFI on his 70 Charger. The car has the Mopar electronic ignition using a new engine harness that has the electronic harness built right in. The EFI requires 12 volt key on power for the computer. Needs to maintain constant 12 volt power while cranking. My thoughts were to tap into the hot side of the ballast resistor, but we found the voltage at the input of the ballast resistor drops off significantly while cranking. A friend suggested using this ballast resistor point to run a relay for direct battery voltage. Anyone have suggestions? One simple wire is holding us up.
