#3 - Stripping the PS2 Cable: First step, of course, is cutting the wire at the spot of breakage. Be sure to cut out the mm or so of messed up wiring, or just plow through it with the cutters. Take the wire cutters, the actual cut part (unless you have a super duper huge stripper) and lightly squeeze (enough to get through the rubber, but NOT into the innards of the wire) around the wire. This should enable you to fully remove the rubber shield around it. Directly below this rubber is a strange wire crosshatch of copper (my best guess for its purpose is magnetic shielding [reduce interference]) and below that a paper/cloth tube (thermal control?). That stuff should peel back or rip off, leaving you with 8 (I think) different colored wires.
#4 - From these wires, strip them (I used the 24 guage (.5mm) stipper spot on my strippers) down. The wires inside are very interesting, and don’t be alarmed that the wire looks like cloth on the inside. I thought at first: Oh fuck! Fiberoptics! but the inside of each colored wire is really a ridiculously thing copper strand wrapped around a piece of string stuff (fuckin crazy robots). The nature of these wires are thus altered (the reason I had to solder, they don’t just twist together). Soldering these wires is sure one hell of a pain in the ass, but possible. I taped the end that goes to the PS2 to the bottom of the HRAP so it would actually stay in place, and then proceeded to solder/tape the wires up. At certain points you need rougly 6 hands, but it’s managable.
