Sony cassette deck model EXR-14 diagram requested

[RoscoePColtrane]

hello

I have a Sony cassette deck model EXR-14 that I got from a flea market. However there's no cord with it to plug into the car so I can't determine where the positive goes, the speaker, etc. There are 10 small prongs on the back of it (where the cord would plug into). I don't want to buy any cords. Does anyone have a diagram that shows which prong on the radio is the positive, the speaker, etc? thanks
