Thanks in advance
There is going to have to be some kind of pressure transducer and it is most likely mounted back near the tank or in the compartment where the compressor is. I'd start there and see if you can trace the wiring from that point.
I'm guessing here but I would imagine that it will have one wire that heads up towards the front of the motorhome.
Unfortunately thats about all the clues I can give you.
