Did you discover an unused/unplugged plug - like a DIN-plug, see the image below - in front of the sink and behind the left seat of your Beta 2S Self-Contained Campervan and wondering what it's for?
No worries about it. That plug is part of the vehicle's previous life, being a luxury car in Japan. When the vehicle was imported from Japan it had a DVD-player in the back of the chair which was removed. The plug does nothing so can just be left as it. It's what we call a nothing plug.
