The sensors are on the left side of each tank that would be the drivers side. I wish I could supply the resistance for you but I replace my set up the the SeeLevel II system. I got tired of try to clean the sensors and not having reading periodically. What exactly is going wrong with yours. It may be crud built up in the tank and that is why I replaced mine. Oh most importantly you have to drop the belly to see the sensors follow the wires. I cut mine at the dump valve to make it easiser to get it there. And used gorilla tape to close it back up.
