Step 4 Chop up the back.

now you need to make a space in the back for battery and the wire from the module to the battery.

now take a pen and cut out a canal in the back for the battery wire. make sure the canal stops underneath where the electronics will be on top.

now take a pen and jam a hole through the styrofoam from the front to the back. make sure the hole's wide enough to push the battery connector through.
