|Here's how my adaptor looks:|
Holding the laptop drive so that the pins ar toward you, and the bottome of the drive down
(circuit board side down)
On my drives, there is the main connector, and a group of jumper pins isolated with a space off to the right side.
Now, plug in the adaptor, this should result in the power leads bien on the left, again, with the isolated "jumper" pins off to the far right. On my adaptor, the red POS lead is on the bottom.
Pin 1 for the IDE ribbon is on the far right, being marked by a small paint dot on the adaptor.
