Here is a helpful little chart, It doesn't have the standardized wire colors (yet?). It is a mix of a lot of paint, and OI manual, but it tends to help me think. I have the colors written on a dry-erase board in our robotics room... at least I hope they are still there. I will attempt to revise the chart when/if I find the color chart.
Could you just go to radioshack and buy a standard DB-15 pin connector instead of using a spliced serial?
