Connect the wire harness to the connector on the PCB. Wrap the USB cable around the notches that lead out of the casing. Now, VERY GENTLY, put the controller back together. Watch out for pinched cables and pinched Teensies! Take your time with this, it takes me a couple minutes to get everything situated just right. Put the 5 screws back in and bask in the glory of your hard work. You now have a USB/PS3/KEYBOARD gamepad that can be reprogrammed to be whatever you want it to be!
