    Need Help Identifying Where Some Wires go on an old radio

    I Have a Blaupunkt AM/FM/Cassette unit. Its says it is a model CR-4073.

    There are four wires in a single connector in the rear. I am guessing one is for 12v power, one is the common for the speakers and the other two are for the left and right speakers. There is a separate antenna connector and ground lug as well.

    The wire colors are black, white, green and red.

    Anyone have a clue as to which is which?

    If it helps anyone, there is also a tag that says: "Made in Japan for SAAR in Brussels".

    Well, I got lucky. I was rumaging through some old papers I got with the car and found a package of papers for radios. Most of them were for a Blaupunkt Frankfurt but one two sided sheet was for my AM-FM Cassette unit. How is it wired?

    Red - 12+v
    Black - Common for speakers
    White (or grey) - Right Speaker
    Yellow -Left Speaker

    I hooked up my battery charger as a power supply, hooked up my speakers and voila! sound!
