Step 6: Put the USB cable on a diet
The head of a USB cable is fat. We need it slim so it will fit inside the SNES controller case. We are going to cut away the rubber housing around the connector. Put the connector on it's side and hold it with pliers. Follow the edge and cut gently with a blade for each side. WARNING!!! DO NOT PUT YOUR FINGERS NEAR THE BLADE!!! When you are done it should look like the right side of the picture. Wrap the wire we just exposed with some electrical tape.
