What exactly did you mean by "black pin that most connections have"? It looks like a regular Molex cable. these things are very hard to repair. The best thing to do is get an 80-conductor cable from a hard drive. The 80-conductor was used to help cut down on cross-talk and noise. They are small enough to replace the Molex cable and they are also single strand copper wire. Cut the hard drive cable to the length you need and peel of the number of wires you need. They don't need to be individual unless you want them to be. With a low wattage soldering iron (15-20 watt) heat the Molex cable and gently peel it away from the circuit board. After the cable is completely removed; clean the solder pads with desoldering braid. This will leave the pads bright and shiny and leave just a little solder on the pads to make the new wires stick better and more easily. Strip about 2mm of the insulation off of the end and put very small amount of rosin on the wire and then put a little solder on the wires. The rosin makes the wire heat up faster and the solder to melt faster and adhere to the wire. It only takes a second for each wire so take your time. When all the wires are done, touch them to the pads on the "keyboard" very lightly with the soldering iron (also just a second for each one). And try not to get the wires too close to each other. The other end of the new cable can be connected with the hard drive connector (just be sure to know which wire is on which pin using an ohm meter).
A picture of the other side of the touch pad would be good also.
Hope this helps.
