I believe what you are referring to is where are all of the electrical items such as Converter/Charger, fuses, circuit breakers, etc. Those are all located in the electrical compartment of your RV. The electrical compartments are normally located in one of the outside storage compartments of your motorhome. .
I cannot tell you the exact location of yours. Just start at the front passenger side of your RV and open up the outside storage compartments. You will definitely know it when you see it. If you go into a compartment and you hear a humming sound you will know that you found it because that is the noise that older Converter/Chargers makes.
