Gadget Audio equipment Cable Wire Electrical wiring

Can anyone tell me what this cable does please. It connects to a same coloured socket on the back of the head unit and has a small circuit board on the other end. Can't find a diagram which shows the rear sockets of the NTG 4.5 head unit anywhere.
