Step 1: Materials
A 9v battery
A 9v battery clip (thanks to the instructable on how to recycle 9vs i made my own)
Step 2: The wiring
First strip the wires so they dont have the computer connect thingy
The red and the black wires are the ones you need.
If you dont have red and black wires i guess your going to have to figure out which ones are negative and positive.
Wire the positive (red) to the red of the battery clip and wire the negative (black) to the black of the 9v clip
Step 3: Switch design
It fits nicely where the screw holes were so i decided to put it there.
For this step you will need a dremel to cut the plastic so the switch will fit.
You will also need a drill to make the switch fit in the hole.
You will want to drill a small hole somewhere to put a wire tie in
The picture should show were i cut.
Step 4: Wiring the Switch
Cut the positive wire and solder both ends to the switch.
Step 5: Your Finished
I wanted to put in blue leds but i didnt have any.
