Extra Winnebago One-Place Monitor

I purchased one of these (~$30 with shipping) several weeks ago to mount & use in the water bay to monitor the tank levels when using the black tank rinse. Or it will plug and play at the original location without the generator functions. Last I looked, Winnebago has them in their store for ~$300. I haven’t installed it yet because we are camp hosting but I’m thinking about mounting it to the bay ceiling on a hinge to fold it down when needed. Looking at schematics, it appears that diodes must be put in the 3 lines for each sensor for each monitor. I thought someone else may want or need one.
