I have older style connector. Black and White wires were twisted together but, connected to ports you describe in your video. The rest are for sure Audio. It would not be hard to connect left/right microphones to respected sources. Could one guess that two microphones are for outgoing in stereo?
why do we need to identify the power positive using a tester, cant we just alternately switch the wire to know if it will power on? will it damage the camera in case we connect the power to a wrong wire?
since these components are integrated, they do as much as they can to be small, so they avoid putting some protections because they're not customer-grade and meant to stay connected internally.
