Electronic Boxes in Boot

[BennyHill]

Please can someone tell what the 2 electronic boxes in the boot are for. Photo attached. Thanks.

The one on the left looks like a 12v rechargeable battery. Could be a tracker and back-up battery

Can someone show me the ariel cable.

The silver metal box on the right has 3 wires feeding into it.
The box on the left looks like a battery, and is linked to the silver box by 2 wires.

Not sure if there any any aerial wires.

Thanks
