A simple set of proper splicing devices and a crimper. I have one that I keep for such work and it was from Radio Shack. Just a tip. Unplug both ends while working on it and do not untwist the wires too much, then match up the colors.

There is a cable that runs through the house and it got cut or whatever happened to it...thing is there is no way I can replace it...is there a way to replace the little connector at the end?!?...then use a fresh cable to extend it some how? like connect the old cable to something then the new cable to the other side hence extending it?
