POWER SOURCE

Installing a EFI system that needs a power source that's hot with the key on or in start position. the electrical system has been changed from original. Can't seem to find any circuit that fits the bill!

Surely there is somewhere on the back if the ignition switch that fits the bill .

look at the back of your ignition switch and follow the turn to the contact points to find your wires. you need constant hot on and with starter.

With all due respect, if that is causing you issues please seek help with your install. Those are some expensive parts that you do not want to ruin.

Tapping ANY existing circuit for an engine management system really isn't a good plan. I would feed your EFI system directly from the battery through a relay. You can use a feed from the ignition "ON" terminal of the relay to close the relay.
