GLCD pin 19(LED A) goes to a 330ohm resistor then to +5V(Arduino).
Ok, the range of LCD pin 3 to GRND is: +1V to -7.1V
EL inverter like this one?http://www.ebay.com/itm/12V-Battery-or-Transformer-Power-Inverter-EL-3-meter-10-feet-Foil-Wire-Constant-/251107233479?pt=LH_DefaultDomain_0&hash=item3a77284ec7
If it doesn't light up, then more than likely the diagram isn't exactly right for this lcd. I will go back to the first one and mess with the two holes at the side of the display to see if those are the backlight pins.
