Thats a good find. Looks like it’ll work with the 6pin breakout board for standard 12v PSUs.
Also, a good find! Dude your google-fu is amazing.
As a side note, I wouldn’t recommend the CCTV pigtail splitter cables, most (if not all) of them have 5.5x2.1mm barrel connectors instead of the 5.5x2.5mm ones we need.
