There are 2 catalytic converters on a V8 2002 Toyota Tundra. Bank 1 is the manifold and cat on the drivers side and bank 2 is the manifold and cat on the passenger side. Sensor 1 is the sensor on the exhaust manifold before the catalytic converter. Sensor 2 is the sensor located after the cat converter. Bank 2 Sensor 2 is the sensor located after the catalytic coverter on the passenger side.
Yes provided the voltage is compatible.
Yes, a space heater can be plugged into any outlet. Depending on what else is drawing current on the circuit will govern whether the circuit will trip or not. If the heater is plugged in and the circuit does not trip it can be left plugged as long as it is needed. If the heater trips after a few seconds, then try another outlet.
does the bypass valve on elution heater be open or closed
The clicking noise you are hearing could be the heater is overloading the breaker and it is on the verge of tripping This could be caused by the heater being to large for the circuit. Check the amperage rating on the heater and the rating on the breaker It also cold be the circuit breaker is going bad and needs to be replaced by a qualified electrician These are 2 possible answers you also could have a bad (loose) electrical connection some where in the circuit

Load circuit
The Toyota Camry block heater is located on the front of the engine block. You can follow the block heater cord to the block heater.

The O2 sensor heater circuit helps warm up the O2 sensor. The purpose of this is to allow O2 sensor to get to normal operating temperature without having to wait for exhaust pipes to warm up so it can give accurate readings. It is built into O2 sensor.
Bank 2 locates on the opposite side of the cylinder # 1 and the sensor 1 is locates in the front
The block heater is located near the engine on most cars. This is true also for the 2003 Toyota Rav 4.
