Shrink tubing is nice for this. The length of your wires should all be pretty even, not 1 wire 1 inch long and another 10 inches long etc... Your ground and power wires should be 20 awg ( i find single strand wires are the best ). If you have a multimeter around check the power wire for proper voltage. # 2 when soldering the wires to ps2 board points coat your end of the wire with solder and dip in flux.. i cant stress enough, to much solder is no good. Use a low wattage soldering iron... it is very easy to damage or warp parts of the ps2 board. Hey if you have a digital camera why dont you take a picture? well hope something i said helped.
good luck ! :)
