Just guessing about a tank sensor/wiring test since I don't actually have a trailer yet. Possibly something like this would work with whatever the accuracy of the sensors and indicators is. The important thing being the level indicators increase and decrease linearly for the appropriate tank.
1. Empty Grey, Fresh, black water tanks
2. All water outlets off, all sensors level indicators off (0%)
3. While filling Fresh water tank, watch fresh water sensor level indicator increase linearly 0 to 100% while other level indicators off ..if ok then sensors/wires on fresh water tank are ok and in correct order.
4. Turn on kitchen faucet to drain fresh water into grey water tank and watch grey water level indicator increase linearly 0 to 100% while fresh water tank indicators decrease linearly 100% to 0% and black level indicator remains off....if ok then sensors/wires on grey water tank are ok and in correct order.
5. Assuming you can apply water to toilet to fill the black water tank, fill slowly and watch black water level indicators increase linearly 0 to 100% ..if ok then black water sensors/wiring ok and in correct order.
If you wanted to check the accuracy of the sensors/indicators then using an inline flow meter set for gallons (or quarts) could be used when filling the tanks in the previous steps or gallon containers.
With regard to cable, a simple short and continuity test could be a minimal test.
