what's this cable

Good day, when the forumers changed the insurance of the 12v lighter place the other day, what caught my eye?

It doesn't look very original

I guess the factory is able to see this kind of idle cables in peugeot vehicles since it uses a single harness, the cable is going towards the trunk, but I did not know what it is for, if there is no lighting under the door and there is no foot part lighting, you can see those cables if you have a little tamper, also inside the doors. The lights for the lights and the folding mirror are ready inside the doors. In 308 we disassembled our own door and 308, the situation was generally the same, there is no electricity in the cables, but it needs to be opened.
