Found this electronic box mounted on the rear trunk wall of a 3rd gen donor car(by the trunk latch pull down). I am not sure what it is/was. I have no need for it but I'm just curious.
Has a power and ground wire. The ground has a non-factory style terminal. The other wire is like an antenna wire that goes to a few "tuning"? screws, and then a mono RCA style plug into the box. No other wires or inputs/outputs. A search of the numbers on the tag turned up nothing.
I don't know if its a stereo component, an aftermarket antenna, or a lojack type device.
