wiring for EFI

IGN2 only goes one place........from the ignition switch which is a separate contact .........to the coil+ side of the ballast "which you won't have" anymore.

See, there are only so many switched outputs from the ignition switch..........

ACC........hot in "run" and in accessory, dead in off or "start."
IGN1......."run" hot ONLY in the run position, not start
IGN2......."bypass" hot only in start position
START......normally yellow, fires the start relay "hot" only in start

There are some other things IGN1 feeds.....the cluster, warning lamps etc, no big deal
