7. Wires and connectors in the engine wiring harness may be modified or replaced.

No longer a limit to use OE harness... You need an ignition signal for tach and a sync signal for sequential I promise it is not hard for those that want it.

Joe, the fact that it offers "modified" and "replaced" as options, but not "added" or "removed", is deliberate. It still might be possible to convert batch to timed if the wiring is right, but the new rule does not permit adding a whole bunch of wires that weren't already there.
