That would be f10 20amp Ignition switch fuse he's referring to, which incidentaly feeds the PCM relay coil. So it would knock out everything that f9 does, plus more, resulting in a pretty dead car (electrically speaking).
If fuses are OK good chance you're into loose wiring connection(s) at the main distribution box; considering the major harness replacement you've had that is distinct possibility.
Not the area to poke around in without disconnecting battery.
