hahahahhahaha..... sorry, the guy you bought it from didnt know what he was talking about?
the wiring is equal to gameplayrf with right trigger/button only. (assuming the chip is turned top down deadbug.)
but, I have never modded a wired controller, I am sure there are considerable differences, but my fist thought would be that there is no resistor on the led so it is probably fried, unhook it and see if the led works without the chip attached.
