How to connect up original AM radio?

[calpolymustang]

I'm trying to test out the original AM radio, but don't have any schematics that show how to hook the wires up.

I have:
black wire with yellow plug
blue wire with red plug
and a pair of black wres that go to a male/female pair plug

Any advice is helpful. I'm not sure if my dial light is just broken, or if I'm just not connecting it right.

Anyone know what a good condition AM radio goes for if it works?

It looks like wire #137 is Yellow w/blk The two wire moulded plug should be the speakers. You can figures out which one is ground with a multimeter. The diagram doesn't show any other wires.

I think that the chassis is the ground, and the wires are power, lights, and then speakers.

Thanks for the help.
