Hello
its an IdeFix97 4 way adapter for A1200.
If you want to use even the second channel (Port1), you must install the IdeFix97 software (on PowerComputing site there is even a free registration details)
Otherwise if you use only the Primary (Port0-both 2.5" and 3.5") you will no need IdeFix97 software installed.
As already said by filson, the "Input" 44 pins connector, must to be connected with a short 44 pins flat cable, to the A1200 mobo.
Bye :-)
EDIT-yep . . . red wire is n.1
