I may be wrong, but it seems like the Molex 4 pin Computer Connectors are backward. Looking at the Male connector/female pin plug that comes from the power supply, with the flat side down and the top slide with slopes up, is that it goes 12V-N-N-5V. When I use the Sparkfun Molex Vertical connector, says 5V-N-N-12V. Am I missing something or is there an error?
Are you sure you are looking at the correct side of the board and are you thinking of looking at it from the correct side? It is easy to get mixed up that way.
