What brake on/off switch? Was it just for the emergency brake being on, or something on the hydraulic circuit?

The catalytic converter is not needed for the most efficient engine operation, but the engine does have to have misfire detection to avoid catalytic converter damage. However, the engine would run a lot cleaner with the cat, and the air pump.
