Got my radio today. Bench testing, I connect the B+ and ground wires and I can load discs, see the clock, that's about it. Does anyone know how these 04+ Class II radios receive their "on" signal? I wonder if it's through the class II data wire, since there is no switched 12V on the harness. I did find a pin diagram, and their is a switched 12V pin but no wire is attached. I did apply +12V to that pin but the radio will still not turn on.
Any ideas? I know it's possible because someone on another forum put one in a Fiero
