The plastic connnector in my picture does not connect to your monitor. Your original plastic connector stays in place and the wires from it connect to the wires from your vga cable. I referenced that plastic connector because it is a convenient way to splice the cables together.
Ok, I think I got it. The original connector I have stays there.. I then cut the wires running from it (since it runs and connects to the 'wiring block' then out to the VGA connector and god knows where else)
actually, I may just go through and cut the wires running from the plastic connector, cut them a few inches from the VGA connector pins, and then splice/electrical tape those wires back together. That should be fine, right? Then run the VGA cable from the VGA connector to the ArcadeVGA card..
