Help with RGB to NTSC Encoder

[twin paradox]

I recently found a free street fighter 2 arcade cabinet on craigslist. The original pcb was inside but it appears the guy had tried to convert the arcade into a mame machine and quit halfway through. He replaced the the original monitor with a de-cased television. I want to restore this machine to a street fighter 2 but I don't have the money to buy an arcade monitor.

That brings me to my point. Instead of buying a new arcade monitor, I instead bought an RGB to NTSC encoder so that I could display video from the street fighter pcb to the television. My only problem is that I have no idea how to wire it up. The encoder came with no instructions, there are no instructions on the website and no one at Jamma Nation X has responded to my numerous emails. I have tried to take enough pictures so that some of you knowledgeable people might be able to lead me in the right direction.

Oh and just FYI, the adapter comes with an s-video and an rca jack. I am planning on using the s-video jack (which is why I included that in the pictures)
