White connector on AirflowPro ?

Hi, another member here on SweC asked me what the white connector on the side of the black ones that connect to the Ram-modules on the Airflow Pro is for. And after he and I have looked around more then a healthy amount and came up empty handed we both thought that we should ask if you maby had an answer.
His(cat_fish_1) guess was that it was a service gate, due to the SG next to the connector on the PCB, soooooo ? what is the white connector for ? because not knowing is sort of annoying me

Best regards.
