If you look at the charger they way you would when you use it with the top casing removed, there are (used to be unless there's been changes) 2 large solder pads in the upper left corner that are plainly marked (+) and (-). Thats where the connections are made to power the inverter that supplies power to the back light. Like I said not a job for the squeamish. The delicate part is getting the LCD screen out without breaking it, removing all the goo that was used to secure it, then putting it back together with the new EL piece that provides the illumination and getting the Ice put back together. The LCD screen is 2 thin pieces of glass that are very easily broken.

This was going on in '06 and the kits then were more expensive, but included decent documentation with pix, they were about 2x what the ones on eBay are currently selling for. The guy I got mine from had a good business going for a while.
