- Guess on the black is correct, it is 0V. The others are 5V (usuallyy
- Red), and 12V (usually yellow, but not always). There should be two
- black cables, both 0V. The pins are configured so that the center two
- are 0V, and the outside ones are 5V and 12V, I can't remember which is
- which. If you have a drive, have a close look at the silk screened
- text, it may say. If you have a plug from the power supply, the red is
- the 5V.
-
- Note: both the 5V and the 12V are positive, and the 0V is sometimes also
- called ground.

- Dare I ask... howcome the question?
