unless I'm blind but it looks like your soldered to pin 70? But then again I may be blind... I also am counting in the picture which is kinda blurry... but if I am right there is 76 pins on the chip right? and 71 would be the 6th pin down from the top left corner.
Oh... and I just read on a guide made out of research done by the SX crew and it says pin 7. I may be wrong... shit it was a long time ago everyone did that research. Shit I remember when Mal and the rest found the A+B method. SX is nothing the same...
