I found the wire and plug behind the left side over driver's seat storage cabinet. No idea what it's for.
Also the box attached to the roof above.
Anyone have any ideas?
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.
OK so the box is a Beltronics Vector 975R antenna. Though I don't see the display.
