This is the last part of this instructable  and should go pretty smoothly.
1.This was a printer cable. Just cut off the end that goes to the printer.
2. Insert into the hole in the rear of the lantern base.
3. Strip back a couple of inch's exposing 4 wires Red Black Green White, We want to cut away the the Green and the White we only want to use the Red & Black wire's.
4. I have to say the best way to gain access to the tank area was to just grab the Tin Snips and cut the bottom out and be replaced with a thin piece of wood or plastic cover of some kind I have yet to find... But tut tut it's not important as you most likely wont see the underside often unless it's hanging.
5.LED's can't run on 5 volts DC or they will burn out and all your hard work making a globe will be for nothing, so to solve this problem we need to add an resistor to the positive side of the line, I have had great success with 1.4 Ohm resistors I bought on ebay for dirt. You can see the positive side of the USB is connected to the switch on one side and then the resistor on the other side of the switch witch is inturn wired to the positive wire going to the light board. the Black wire (negative) from the USB  is wired directly to the negative of the light board thus completing the circuit. 
6.Turn on your light & enjoy!

question, how hard would it be to wire in a battery pack?

Very easy.
Just don't exceed more then 4.5 volts without a resistor.
thank you
