This is how to add an extra button to ure xbox controller that will turn on/off ure xbox.
first off open ure xbox
now remove the front panel and solder some wire to the on/off button (bottom left or bottom right)
then tape it down
now, locate the yellow wire comin from the first port and cut it
now connect the wire soldered to the power button
solder and tape
now, grab ure controller and open it
locate the connectors on the front of da controller
now find the yellow and ground
solder some wire onto ure button as shown(sorry, i dont kno the name of this type of button)
solder ure button to the yellow and ground

next, grab ure controller case and find somwhere to insert ure button
theres a tight squeeze where it put it so no glue needed
