The 2jz pinout diagram shows pin J1 B20 as the LSUH1 which I assume is for the heater. What pin should be used for the second o2 sensor heater or do both sensors have to have their heaters externally powered?

For the external wideband each sensor has each of their wires assigned seperately except for the switched 12v power.
