I had an idea, but couldn't verify it until I found this PDF: Lexus TSIB Engine Bank and O2 Sensor Identification.
Bank 1 Sensor 1 is almost always the first sensor (before the catalytic converter) on the side of cylinder 1 (1st in firing order). So in the case of SC400's it would be the incredibly difficult to reach sensor on the drivers side exhaust header.
