Okay so, this is the little idea I came up with for the custom controller plug. Basically, I needed a plug that would carry 3.3v for the controller, 7.4v for the screen, Audio/video, Data, and the proper grounding.
Tested, and works well. If you ever need anything like this, I just used male and female DB-9 connectors, along with a cord from a PS2 controller, which conveniently had 9 wires.
This is awesome! I May have to copy you (and the movie) and put EL wire on every console I own. Because lord knows I have plenty and not the foggiest what to do with it.
