Jumper wires are handy little things that you can pay a lot to have them made, or you can make your own really cheap.
All you need are:
- A piece of LAN wire (you can buy this for 50 cents a meter, or a couple feet), this is what the inside of it looks like. Strip the outer insulator, and get the 4 couples of wires. So we have 8 wires that you can cut at the size you want.
