There should be two that are distinctly larger, they will be the AC power wires, either black and white, two black or two white. Probably 18 gauge wire. The others will be for color and sync, see if any of the wires coincide with this
Red
Green
Blue
Ground
H-Sync (yellow wire?)
V-Sync. (Gray or brown or something else)
Its also possible there is only one sync wire… brown, or something else not Red Green or Blue
MyF1 has a completely different wire connection so you might have to wait for someone more experienced to give you exact info. Usually if you know what the monitor is expecting usually you can decode the wires.
I just looked at your picture closeup and I think I figured most of it out.
Looks like sync is yellow and brown
Power is obvious, they are at one end of the connector by themselves.
The others are color and ground, although I can’t figure out why two green wires. Take a look at the wires on the other connector, it will start to make sense, they will coincide in some way.
That is a standard Molex or Philmore inline 15 pin. I cant tell if they are.062 or.093pins….probably.062
