Renault 25 baccara 1991

Good Evening, or morning whenever this post is read.

I am new to this forum and I have a 1991 Renault 25 Baccara.
I'm currently restoring it after the previous owners. In the luggage compartment in the right wing, I found connectors that I don't understand. Maybe someone explain what's going on there.

Those cables are part of a mobile telephone installation from the 1990s. The cylindrical object is a power filter and the black connector would plug into the main phone body. You should find the other end of the cable under the centre console or behind the dashboard.
