fayko, I thought we talked about this already. 99% of the guys here mod ms wireless controllers, and we recomend everyone use them so we can all be on the same page. as far as your controller and request, I cannot help you becouse I dont have a controller like that, and the pin outs are not the same.
look at the wire that is coming in, this plugs into the usb port, so that red and black wire you see are the 5v supply and negative accordingly.
pull 5v from there
add your switch your new power leed
use a resistor
power your leds
thats all I can tell you without having the controller
