From the Bigfoot website troubleshooting section:
"If you have the "Front/Right" and "Rear/Left" lights flashing on your panel you must disconnect the interface cable at the panel or sensor for 10 seconds to clear the code. The interface cable has a 6-Pin connector at each end. It will be the smaller cable of the 2 that plug into the sensor and the only one plugging into the rear of the control panel."
The level sensor is usually mounted on the inside of the firewall.
