PSP led buttons

[nellafeht]

I was looking at this guide https://www.acidmods.com/forum/index.php?topic=13494.0 but it seems the pictures are no longer working.  I want to add leds under the d pad and right side buttons. Not looking for a trigger or sound mod. Just want to be able to see it in the dark =D.  If someone could point me in the right direction I would appreciate it.
