Coregrafx RGB pins

[Alc]

I'm about to tap the external connector on my CoreGrafx for RGB. The guide on Gamesx says "Remember that this image shows the peripheral, be careful to flip the connections if you're working on the system itself" but not knowing much about how these systems fit together I can't tell exactly what that means, and I'm loath to just try it and see. So:





My assumption is that the top left pin (on the external connector's pin array shown at the bottom of the image) will be red. Is this correct?

There are pics of this board used in an RGB mod here:

Man, I was doing really shitty work back in the nineties.  =D
