How to connect Fisher Speaker Model ST-9315?

[Tech4TB1Me]

Hello. How do I connect my Fisher Speaker Model ST-9315? I tried moving the speaker and the cord came out of the speaker, but I don't know how to reconnect it. There is a hole in the back of the speaker with a positive and negative side and what looks to be a flip switch (black & red). I am sure its simple, but I don't want to make it worse by doing the wrong thing. Although its real old speaker, can you help?

the wires that came loose should be color coded. the ground is usually black, the positive is not. hook the black wire to the black connector on the back of the speaker and the other wire to the red.
