Location of One Connect modules?

[cmulvey]

I've got a 2021 3011DS and have been reading where folks have issues with their modules on various model RVs due to connectors coming loose. I like to be ready for most anything by knowing where items are within my RV so should the need arise I know where to go. However, I've been unable to determine 100% where the various modules are located on my particular model. The switch and router are in the center cabinet behind the bedroom TV. The main board is below the drawers on bottom right hand side of wardrobe in bedroom and I believe the modules may be behind plastic piece in water & sewer bay but am not certain and feel why pull the panel among other stuff if perhaps someone has already been there/done that and can enlighten me?

TIA
