| Grab a multimeter and set it to continuity testing. Touching the leads together should produce a beep or indication on-screen. Determine if you need a 2 or 3 conductor Jack by looking at the plug. If it's a 3 conductor, you'll have the tip, a ring, then the sleeve. If it's 2 conductors, you'll have only the plug tip and sleeve. (Think stereo plug vs mono). At this point, I cut the wire with enough lead in the housing to solder to your new Jack.
now to the multimeter: follow the internal wiring out of the loose cable until you reach exposed wire. Strip them back a bit. Touch one multimeter lead to the exposed cable and the other lead to the tip of the plug. If it tones, thats the tip. If not, continue to the ring of the plug, then sleeve. One of them will form a complete circuit down the length of cable. Note which is which, repeat the process for he other cables. Now you should know which color cable goes to each connector.
When soldering leads to your new jack, just match the contacts that you noted. I've done this a number of times. It works quite well. Good luck!
