We will be cutting a small section off the remaining USB cable to run to the front of the mailbox for the door switch.  Make a cut that is a few inches longer than the depth of the mailbox.  You will only be using 2 of the four wires.  Solder the Green wire and Black wire on one end of the USB cable to individual legs of the reed switch.  A super magnet will be placed on the lid of the mailbox door to activate and deactivate this switch.

Using the second wire bundle, you will need to solder the Black wire to the NeoPixel Ground and splice it to the Black wire from the first wire bundle (see picture).  The White wire should be soldered to the NeoPixel DIN pad and the Red wire should be soldered to the NeoPixel +5V Pad.  The Green wires should also be spliced together.
