    nothing...Some radios have a third wire which would be wired to a hot wire, that either stays hot all the time or is only hot when the Key is turned on. So the plugs are sorta like a "One size fits all" type deal...

    Its there to keep you from putting the plug in backwards. You can buy that cord at any truckstop or cb hack shop...

    I seem to recall the plug casing has a distinct shape to prevent you from plugging in another way.
