5.7 Hemi Swap Tech question

Just a thought, but the ignition switch doesn't power the same wires during start and run. If you only hook the new harness up to one of the wires, it might give you problems. I know you have to hook both the blue and the brown wires at the ballast resistor to the harness on a Magnum SMPI swap. Maybe this is only a later A-Body thing, but thought I would throw it out there.
