Hello 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? Thanks -Max

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