    Q:
    Assuming that is the one at the bottom of the radiator with the 16mm x2.0 threads. What electrical connector fits this part? Just installed new sensor; however, the old connection blades are stuck in female connector from ECU after rusting/corroding away. Posted by Verified Customer / 2000 Lexus RX300
    A:
    82111-48060 is the only wiring harness for the front of the vehicle.
