That was me. 8^)
I was attempting to reach the poster who knew the solution was blue+green, hoping he'd know about the brown and red cables.

No, haven't traced it but it is on the same rail as there's continuity.

Wouldn't that be the grey 18AWG wire?
The front panel on the array had an amber/green status LED.
Green for 'no error condition' and amber for drive/fan/PS or temperature error.

Yes, it is very well designed: redundant PSU and Fan canisters.

That is what I've been thinking, especially being 24AWG.
But if it is a voltage monitoring function like the 3.3V sense wires in the ATX design maybe(?) would be necessary for stablility.

OK.

Yes, I have to set up a test rig once I get everything mounted.
But no scope, just a mid-quality RMS meter.

Of course.
I still have draw up how I'll divide this all.
Probably two separate +12V posts, two separate +5V posts and two stacked USB charging plugs, everything properly fused.
I still have to decide if I'll be using 5x20mm panel fuses/holders or maybe spend a bit more and wire in polyfuses, particularly on the USBs.
Thank you very much for taking the time to answer.
Best,
