The photos you sent me were of a hard drive connection plate. The connection pins you want are situated on the motherboard itself (normally on the bottom right) this should have some printed letters on it which are abbreviated forms of the connection names such as ATXPWR is the power cable.
I hope this helps, if not, send me some close up photos of the motherboard pin layout described above, and I will tell you EXACTLY how to reconnect this.
