Dreamcast Nyko VGA to RGB problem

[Cruo]

Im turning my Nyko VGA adapter into an RGB cable but I have run into some bumps.

I have located the red and green lines, but for some odd reason the blue line is eluding me.

One would usually assume blue would be right beside R and G but, barring some other problem, I cannot find it. Everything looks great save for the obvious lack of blue tint.

Does anyone know which wire carries the blue signal on the Nyko VGA adapter. I am using a 1084sD2.
