Yes, red should be the shorting point, and yellow the terminal. What is the behaviour you get? Are all other voltages correct? Do the chips get warm or hot when powered?

How can you say that without measuring anything?

Does it come up on SATA when you short the 2 pins and power it up?
It should provide a RAM-disk on SATA with approximately 80% of the RAM size as the disk size.
