911SC Oxygen Sensor

These questions apply to an '83:

Can the Oxygen Sensor be replaced without the special tool described in Bentley's?

Is the box underneath the driver's seat the Oxygen Sensor Control Unit?

The process for testing the Oxygen Sensor, described in Bentley, is unclear to me. How can one apply a voltmeter to test, without disconnecting the Oxygen Connector Harness? That is, how does one go about testing the Oxygen Sensor?
