HELP! Dual modding ps3 TE > 360 to be autodetect

I am working on a PS3 TE stick.

I have chIMP SMD and fightpad wired together autodetecting on each system already.

My question is: How do you get the Guide/Home button working from the controller? Do I continue to use the original ps3 PCB or is there another way to wire up the Guide/home button?

I have searched for a solution to this and if it is in the forum somewhere please point me there.

What fight pad PCB are you using?

just padhack that middle point where the home button is?
