I just made my own mod using the pinouts provided. An easier way was to use the Wii Composite cable, use the 3-rca connectors as your Y, Pb, Pr. Crack open the black part of the connector out, just by sticking a flat head screwdriver in between the gray and black and pry out. Then use a sewing NEEDLE to poke into the front part of the connector to pull out the pins carefully. After all the pins are out of the connector, use the NEEDLE to make the little locking pin stick back up a little bit so when you put the pins in it's hole, it will stay put.
Just rearrange the pins to the correct holes using the diagram provided here. I had to connect all 3 ground, but I get Black and White video. I haven't connected audio yet. But doing this way seems alot easier than the Alligator clips and Paperclips. The secret tool is the NEEDLE!
So if someone can solve my Black and White issue, then this could be the most easiest cable mod I've made for a console. Last time I made a vga cable for the gamecube with success and then sold on ebay.
