1990 Las Brisas holding tank panel and wiring

[JackW]

I have a 1990 National Las Brisas and none of my holding tank sensors seem to work at all. The Battery and Propane circuits seem to be fine. Thw panel is one with 5 push buttons...One fo each function and the water tank switch.
The display is 5 leds showing one quarter incrments...I took it apart and there is no indication anywhere who made the durn thing and it appears that the sensor wires are torn lose...But I dont know which goes where! So does anyone know who made it? Or have a wiring diagram for it? or where the heck to look for the same?

Thanks

Oh and one more thing...Each tank has only 2 sensors to them....Any one know what I can do?

Where are the wires torn loose from? The control/monitor board or at the tanks. It appears that my monitor is simular I can check it to see what the wireing looks like but I have no wiring diagram.
Personally I do not use them. We are full timers and I just dump once a week with the black and the gray is always MT. If I am dry camping I pretty much know how much I can put into them before they get full and I keep them under control.

Well I think Im just adapting to not having them... Thanks for the offer but I think Im just gonna use the old look down the toilet method for the black tank and as for the grey tank, if Im not hooked up to city water, I dont think I can fill the grey tank without running out of fresh. I might try and figure out how to connect the fresh watertank sensors but its not really a priority right now.
