Anyone recognize this connected behind radio ?

Seems to be part of the main loom but I can find nothing to attach it to , maybe because the original radio is long gone ?

CD changer?

What colour are the wires to it? Any clues there? Whats this on, your 80/90?

80 series , I left it loose because theres a few other bits such as a dud red dot light button and a tiny antenna on top corner of the windscreen suggesting to me the truck once had fancy aftermarket security ?
