Can’t tell you what terminal does what, But I can tell you how to find out.

Get some jumper wires to attach to the spade terminals on the chime box.

Radio Shack, spade terminals, male and female

Speaker wire to the spade terminal. Make enough so you can unhook them one at a time. Put a male on one end and a female on the other.

When you find what you need just cut the spade terminal off you use a pair diagonal cutters, don’t just try to snap them off. They may brake the circuit board.
