In the valve compartment you will see the bottom of both grey and black tanks (where the valves/lines connect for each).
Follow the line to the base of the black tank with your hand. Then move your hand toward the sidewall; the door hinge of the valve compartment. You should reach the end of the tank (probably hidden behind a fascia panel). That end is where the sensor probes are - if you peek upward with a flashlight you will see the small wires to the probes in the tank sidewall.
