OK i finally did the mod too, even though i have no 360 (Well its coming in the mail this week!!! I cant wait!!!)
It does work cause i put 3.3V on the wire and the PSU will turn on fine. Also i used a 100k resisotr aswell.
Heres a crappy pic:

Now the only problem will be actually connecting it to the 360. I dont have an intercooler (theyre not real common in australia) and im not taking the 360 apart as it has the warrenty till next febuary. Would i be able to try solder the wires onto the metal contacts on the power plug?
I put a tread in the BST asking if anyone has an intercooler or a 360 power lead theyd want to sell me.
EDIT: Oh yeah i also used a BC 548 NPN transistor
