For anyone interested, I have the new controller I believe (CG2), and the mod works fine. I would use this tutorial:
http://www.se7ensins.com/forums/threads/tu...pid-fire.45035/though. It's basically the same tutorial as this, with credits to him, but it's only for the right trigger and it has everything already corrected. Like I said, it works, although right now I'm figuring out why everything is backwards for me (it fires while the pushbutton is up, and stops when I push it down, opposite of what it should be doing).
Also, I HIGHLY recommend anyone that is trying this to purchase a cheap electronic breadboard to put this mod together on before you solder everything. If I didn't do this, mine wouldn't have worked because I messed something up :/
Anyways, hope I helped!
