OK so the first photo is a Sony Uni-Link CD changer control cable. Since I do not have a sony stereo nor a sony ch-changer looks like it has zero use unless I can find a Kenwood CD changer receiver to sony cd chager adapter.
Still looking into the other box mounted on the roof... it has an arrow embossed on it facing front. the connector on the back is roughly square.
Be seeing you,
