I believe the components involved are the 6 per-cylinder coil packs,
the 2 per-bank output stage amplifiers and the engine ECU. So other
than the amplifier doohicky, there does not appear to be any other
component which is bank 2 specific.
I'll have to pull out the Bentley wiring diagrams and trace everything
down to see if there is any bank-specific shared wiring. This seems
likely, though. I was vaguely hoping that someone might have some BTDT
experience with this and would say "Look _there!_"....
