|iMac G4 20" Inverter Pinout|
To be honest I am not sure exactly what the yellow wire does and I can not guarantee that there is not something else missing. I believe its also involved in on/off control. I am not sure about what resistor as I do not know the current, but it would be high - at least 1Kohm.
The TMDS to DVI for the ID Tech panel can be found here. Again this is based on ID Techs own specifications, so I am very confident about in this pinout, but have not tested it myself.
If anyone does have a power source and gives this a shot please let me know the results. Good luck.
