Where to buy 5 conductor cable

Hi all, I hope this is the right place to post this.

I have a problem with all of my nunchucks, the wii remote isn't recognizing them, I open them up and found that the problem is in the cable that connects them each other. The nunchucks are barely new and before buying new ones I would like to fix them changing the cable the problem is, where do I get it? Tried to look for it in eBay and didn't success.

I live in Mexico and this kind of stuff is not easily available. Does anybody have any idea where to get some?

Regards all.
