I'd double check that. There are two wires that are supposed
to be cut. One is for auto transmission and the other is
for CA emissions.

Nope, the computer itself does that. If the ignition booster
wires were cut, you wouldn't get a spark... the Bentley
diagram yet again fails in this area. There _is_ a connection
between the ignition booster and the coil. In fact,
the "ignition booster" is nothing more than the power
transistor that drives the coil.
