Yep, this can be tough. What worked best for me was to tilt the case up on a corner and move it around relatively violently. Once I stopped getting air out in that position, I'd switch to a different corner.

The molex connector has two black wires in the middle. They are both ground. Then as alphaOne said, there is a 12V yellow wire on one side and the 5V red wire on the other.

I'm glad you figured out the problem and simply need to flip the pins around on your connector to fix the issue. However, I don't understand how you can be measuring 9.9V on the 5V line...

What voltage does your multimeter show you now that you have corrected the pin layout on the molex connector?
