Bad cords. Replace, or repair?

Here's the situation. I've got an AES stick with a connection that fails intermittently and otherwise works perfect (I may have even posted about it before) I determined the problem is right where the cord meets the connector which plugs in the consoles controller ports. at first I thought it was the port might have been loose, but I tried the stick on my friends AES and though it stuck in more securely, it still had the same result. And the little rubber rings that reinforce where the cord meets the connector look like they got snapped, so something evidently happened (I'm thinking someone stepped on it while it was still plugged in on the floor and nobody wanted to tell me).

At any rate, does anyone know a good DIY guide to re-wiring the controller ports (EG clipping the ends off, and re-attatching the wires for a new/unbroken connection)? or would that kind of venture be a silly idea and a potential waste of something that still sort of works?

As long as it isnt an internal problem with the stick itself, you can just cut the connector and wire in an port from a neo extension cable. I think JNX has them for sale still.
