Am trying to see if a couple of old radios work. Of course, there's no plug under the dash, just the part on the back of the radio where the plug is supposed to go. Looking at the rear of the radio, does anyone know which of the 3 contacts are what? Am assuming that 2 of the 3 are for the speaker, one is the hot one and the ground is through the dash? Thoughts?
