Backlight

I have acfah4002ayybjp 40x2 display and I was wondering if anyone could tell me how to set up the backlight so I can turn it on and off with the software? I have found some schmatics that look like they might work but there is a disclamer of the bottom stating that they do not know it they work. Anyone have any experience with this?

You could build it, but youll have to then write your own software to control the whole LCD (not just the backlight), because there isnt any software i know of that will let you do it.
