Things You'll Need
Instructions
Turn your Xbox controller over and remove the screws on the outer sides of the back of the unit.
Remove the back case of the Xbox 360 controller. The C15 circuit board will now be visible in the front housing.
Plug in your soldering iron and allow it to warm up.
Solder one end of both of your lengths of electrical wire to the terminal at the base of the push button.
Solder the remaining end of one of the electrical wires to the silver terminal near the LED light at the top-center of the circuit board.
Solder the remaining end of the last electrical wire to the silver terminal on the motherboard just to the right of the right analog joystick. The push button will now be connected to the board via these two wires.
Use your power drill to drill a hole in one side of the grip area of the rear controller panel.
Slide the push button through the hole and place the controller panel over the back of the controller.
Replace the screws on the panel and tape the base of the push button to the plastic of the controller panel.
