Just FYI, your camper was never sold in North America and there are only a few users here in the forums from AU, none of which I remember having a 21 Swan Outback RV. I doubt anyone here has a 2021 Swan Outback, which is why no one has provided you with a photo.
However, there are many of us here that have seen and understand a lot of Jayco's 12v common wiring setups, so perhaps if you shared a photo with what you have, that may be of value. Otherwise, you could perhaps trace \ follow the cables on yours or perhaps better yet, if your dealer is nearby, they likely could tell you easily enough especially if they have more of the same model on their lot. ~CA
