Your A is correct, I will leave it at that as not 100% sure on the others.
Thanks!
There are two 18 AWG wires (black and white) coming from the 3 posi ''AC IN'' connector and going to the 15 posi ''F'' connector. Also, there are two more 18 AWG wires (red & orange) coming from the 5 posi connector ''CN 902'' (I don't know what is that connector, maybe the Degaus ''DMG''?) and also going to ''F''. All four wires are going across the clear red sheat. The shema below illustrate this wiring. I guess this is all the wires which should come from the monitor to both Jamma and PSU. Can you confirm?
p.s. ''CN01'' connector, from down to up : R, G, B, GND, H (I guess V-Sync), and V (not used).
p.s. what does ''OTL'' mean?

I see, yeah it sounds logical.
Now, Id like to show you how that wiring was modded by the last owner of the cab. He added some connectors I don't know their uses and Im planing to remove them since I want to rewire the whole stuff with only the strict minimum (to play only 1 player 15k pcb). Just by curiosity, what's your opinion on this? Some of these connectors looks like Namco power plugs, but very not sure. All those wires was based under the CP...

The Namco power plugs are JST VH connectors:

The button is for degauss.
MS9s didn't just come with Sega cabs, they came with all sorts of cabs from different manufacturers. The 5-pin Mate 'n Lok connector that has power and degauss likely came from a Namco cab. So whoever put that monitor in your cabinet just connected the AC lines with some close end connectors to the cab wiring and called it a day.
As for the ground wire that's not connected to anything, monitors in Sega cabs are never grounded. There's a reason why it's missing on the 15-pin AMP UP connector.

Is it a way to demonstrate that the monitor is coming from a Namco, or another cab than a Sega? I mean, even if theses MS9s were also used by others manufacturers, is it a specific sign/detail on the monitor or its frame (english warnings for exemple) who can prove for which cab the monitor was dedicated as basis?
Some models were specifically made for manufacturers (like 29T for Taito and 29SU for Sega), but other than that, not that I know of. I've seen that 5-pin connector used in Namco cabs, I think that's the only discernible feature.
I see.
I discovered there are two 22 awg wires going out from posi 1 & 3 (OTL/OTN) of one of the ''CN1'' 9 posi connector based on the PSU (pls see shema below). They were extended with a 18 awg thicker wire, then a ring conn were hooked to them. Where goes these two rings and what are they for?
Also, still from the same 9 posi connector, there are two wires going to a 12 posi connector also based on the PSU (on CN3). These two wires are going to +5V & GND. If I remember well, these wires was connected there with that only 2 posi connector. Can you confirm that's correct?

I have no idea what those two ring terminals are for.
As for the 2-pin connector, no, it doesn't not connect to CN3. A 12-pin connector will go there, not a 2-pin one. You will blow the PSU if you do that.
EDIT: I just checked the PSU in my Astro City. The 12-pin female header on CN3 is unused on mine. As for the 2-pin connector, I don't know where it's supposed to go to. But it is for AC. It doesn't leave a whole lot of options.

That 12 posi is missing. Only the 2 posi is here to complete the set.
I'll study the rest of the loom and finish the shema, then maybe you can tell me which ones I can take off and what I should keep. I felt the wiring of that cab is weird..

I've dismounted the whole plate yesterday and packed/referenced all components based on it (noise filter, rocker sw, etc..), but I don't remember clearely if these rings where hooked there since they weren't when I dismounted the plate. I should have taken a picture earlier, before dismounting the cab but I've forgotten.
