well, I tried to find a link for a general schematic, but no luck, maybe hit up the cable manufacturer and see what they have to say for them selves, or google it with cable make and model # if you still have it.
But next time go through an expansion slot in the back. Bend the tabs above and below so as to make the hole wider at an angle. Then push the Parallel Cable through but doing so slightly sideways. Once it's through, straighten out the tabs.
These are all good links but they still dont have exactly what I need. These links all tell me what each pin is used for. Ex. +Data Bit 0 & -Data Bit 0 Return (GND) but none of them tell me which color wires go to which pins??
Ex. green w/black stripe >>> Pin 5
blue w/black stripe >>> Pin 7
Not all cables have the same colored wires. I suggest a continuity meter, go thru each wire (clip one end to the cut end and somehow stick the other into the plug) and record what wire goes to what pin.
Sidenote: if you cut it shouldnt there be some wire still left on the plug you cut off?
