Molex Pins Mixed Up... HELP!

Ok so I went off and decided to sleeve my PSU. Took me awhile but I got off all the molex connectors. And of course I didn't label the wires (Kicks self several times).

Now I have one orange and one yellow and I know where they go (I can refer to the molex connectors left on the other cable). But I have 2 Black wires that are exactly alike.

Is there any way to determine which goes where (the auctual voltage that these are supposed to be I cant remember).

Here is a nice picture of my problem..

abcd - each letter represents a wire

A= Yellow
B= Black
C= Black
D= Orangish Red

Its B and C that I have mixed up.

HELP ME PLEASE

(Let this be a Cable Sleeving lesson.. LEARN FROM MY MISTAKE!)

the black wires are ground

so i dont believe that a matters which hole it goes into

im pretty sure...

Correct, all the black wires of a psu are grounds that all go back to the same solder pad inside the psu case, about the size of a quarter, and they all interconnect.
Just make sure you have the reds and yellows in the correct side, as your drives will go boom if they aren't....
Use a fan connector (molex type) to make sure.

Ok thanks. Ill take your word that they are common grounds.

[says a little prayer that they are]

They are dont worry and no need to pray.

As for location of the wires use the back of a Opticle drive it lists what volts each pin connector is. Yellow is 12v and red is 5v. Black is common ground...
