Here is a site that has the tear down of the 3Gs: (The link is messed up so you have to type it in by hand. Sorry. ) See image above

Look at photo with step 2. If you click on the image it shows item #1 is LCD Screen, Item #2 is digitizer. I would guess the last one ( under #1 & # 2) would be your backlight power. (guessing)

The 3G looks to be the same as far as these spots indicate.

Hope this is what you needed.
