I have a Cobra am/fm radio model 105 GTL that I'm trying to figure out what wire goes where. This is NOT a cb. It has this plug for some unknown purpose that I'm going to cut off but I don't know what wire color does what. I know red is power and brown is the ground as these two colors have already been cut out for a prior use. I'm pretty sure yellow is memory and really pointless since this radio doesn't have presets or anything like that. Now the colors remaining are white, grey, black, orange, blue and green. What wire does what. Is each wire separate for the speakers and not paired?
