Basic USB Wiring Help..

[rawfuls]

Another stupid question.

Gonna make a USB extension cable because I need some more length from the outlet to my bedtable for my iPod dock.

First question, anyone have the wiring diagram?
Looked a few up online (found some, but they suck.. maybe I just stink at googling), but couldn't distinguish which pin was which.

I have a male USB cord, and a female socket... No wires connected to that...

So I don't know which pin is what color.

Also, any "interference" I have to worry about or anything without the shielding...
