Also, Michelle of Alliance Service said in the 395DS, the Control Box is behind the bottom drawer. She sent me a picture of an earlier model which only had two drawers in the rear bathroom. Ours is a 2025 and has three drawers. I asked her which drawer now that there are three, and she replied the bottom drawer. I have not verified this location as my 395DS is at the R&L RV Sales Dealer as my Macerator Control Panel shows "Full" even though the main control panel of the 395DS shows 1/3. I have had it there twice to be corrected. They failed the first time. I do not know if they corrected the issue this time. I plan to drive there in the next few days to verify they have or have not corrected the issue. I knew I needed the wiring schematic and pictures from this forum before I saw A&L face to face. I will have plenty of education and facts so that I am fully educated.
