Secondary Panel
A smaller, three tank, panel is installed in the vehicle cab for a secondary reminder.
Again, it is made by Snake River Electronics and it reads the same sensors as the main panel. Specifically, it monitors the lower fresh water, grey water holding and LP Gas tanks.
Here is the wiring list for the panel connector:
| Pin | Use | Panel | Sensor | Extend |
| 1 | Power | Red | Battery + | Red |
| 2 | Power | Black | Battery - | Black |
| 3 | Tank 1 | Violet | Red | Red |
| 4 | Tank 1 | Blue | Blue | White |
| 5 | Tank 2 | Orange | Red | Red |
| 6 | Tank 2 | Yellow | Blue | White |
| 7 | Tank 3 | Gray | Red | Red |
| 8 | Tank 3 | Green | Blue | White |
