Dual Modding My 360 TE Stick (Help Needed)

I asked this in one of the help threads but still have not received an answer, so I created a new thread. I will keep it up to date with my progress and I’ll also post pictures.

I am in process of dual modding my 360 TE. New sanwa buttons and JFL stick. I am using a Hori FS3 PCB and I don’t mind having 2 usb cables sticking out. I am about to start wiring them together by using the diagram below.

My question is do I have to connect the Ps3 PCB to the 360 PCB? I’ve read that some have done that, but I’m not sure why, and if I do, where do I wire them together? Never modding a stick before so this is all new to me. I have a diagram of the PS3 PCB here. http://i298.photobucket.com/albums/mm275/mountaindewfkr/FS3PCBLayout.jpg

Thanks for any help.

You really mean no one is able to help or point me in the right direction?

Did you try checking on on Toodles dual PCB thread?

You’ll have to connect the grounds and the +5v/+3.3v as the picture indicates

try the official; thread, its stickied…

It’s also on the Bomberman SE MC Cthulhu Dual Mod topic.
