The next two steps will require a multimeter. If you aren't familiar with how to use one, here is a guide that will help you.

Set the multimeter to resistance (Ω) and check the continuity between the two metal strips and their respective ports located on the outside edges of the connector.

Trace the connector wires on the back of the module to match each port to a metal strip.

If the strips show continuity (less than 1 Ω) to the connector, go to the next step.

If either strip shows an open circuit (OL) to its connector, skip the next step.
