USB cable
 

The USB connector came apart and three of the four wires separated from their solder joints. Those three wires are yellow, red and blue. The brown one is still in place. Is there a standard for this hookup. If so, can someone tell me the order to solder them. Looking from the top the brown one is on the extreme left.

Have a look at the USB cables available for MP4 players on eBay. Here --> mp4 usb cables on eBay.

I think it should have the one you are after. It'll be cheaper to get a new one than to get it fixed etc...
