Poor reception caused by that wire being disconnected may have just been a matter of the different types of antennas used for AM and FM reception. FM reception is better achieved using some sort of aerial antenna, but AM reception can be had using a simple piece of coiled wire, so maybe that blue wire running through the vehicle from the radio to the back spoiler area is actually used as an AM antenna lead?
