So i made a rapid fire controller for the 360 and i soldered it to the middle right trigger thingy and the ground to the 1st LED. My brother was playing at the time so i turned mine on and tried the rapid fire button. For some reason it didnt work. So i tried to re-solder it and it still didnt work. So i sat there thinking and it suddenly hit me....
I was second player which meant the power was going to the second LED not the First. So i changed to first and it worked like a charm. Now i feel stupid aha.
ohhh well. I hope nobody else runs into this simple mistake.
