You can pick up said switches in most electronics shops but a quick internet search otherwise Pin 3 (eject) just needs a short time on ground to tell it to open- take the wire from pin 3 and a wire from one of the grounds (or indeed the black cable on the sata) and either wire it through a switch (push to make preferably but a toggle switch will do as long as you remember to flick it on and then off) or leave them hanging and touch them together. Once you have this you wire pins 10 and 12 to yellow wires.
You can try and generate it (DC voltage conversion when playing with low voltages is about as basic as electronics gets- ) and you can probably even do it "in wire" without the need for some stripboard/veroboard.Īssuming then you plump for sata power remember which has 3.3V stuff like exists (do a bit more searching and you can probably find something better- assuming you do not need the splitter then you just want something with a female sata power connection. Your main problem though with trying to use molex power is that it lacks a 3.3v which the 360 DVD drive needs (some older sata drives avoided the need for 3.3V at the cable but as far as I know the 360 is not one of them). "grounding the 3.3v wires to open/close and for open/close signal"- if by that you mean attaching 3.3v to the pin 3 that is ill advised as you just need to connect it to ground. The tray open bit is simple enough- unlike most PC dvd drives the eject is triggered by grounding pin 3. Numbering is looking at the 360 DVD drive. Has a nice pinout on the bottom of the image.
