With the three screws removed, the driver will simply fold up to reveal the wiring. In this case, the color code for the wires is Blue for left and Gold for ground.
Here is the way I connected some alligator test leads. Use a male-male 3.5 mm stereo cable. Attach one lead to the sleeve, the upper part of the connector, and one lead to either tip (front) or Ring (middle) of the connector.
Attach some test points to the end of the alligator cables and touch the solder connections of the speaker (driver). In this case, there was clear sound. This determined that there was no signal going from the connector to the drivers.
