I was given a Dual brand CD player for a car and the Plug was missing and the person does not know where it is, its the one the plugs into the back where the fuse is Its rectangel about 1/2 inch by 1 inch or something was hopeing to find someone that maybe had one that died that I could have the plug? I called Dual and they wanted $45 to ship me one and I'm not even sure if this radio works. Thanks.
