Hi J,
I discovered a much easier way when I built my first iMac 20" project. It requires a couple of careful solder connections on the Molex DVI part you'll be using, but avoids having to obtain extra iMac pinned TMDS wires.
To Complete the DVI connection, I used this method of soldering the 1KOhm resistor directly to the DVI pins 14 and 16. I used an extra iMac G4 wire for pin 15, although it would have been just as effective to solder a small wire directly to the pin, so no additional pinned wire would be required. I did this work prior to connecting any of the other pins. To obtain a VEDID signal, I soldered TMDS 15 (hot pink wire) directly to 3.3V from the PicoPSU.
This turned out to be a simpler solution than rewiring the Vedid/Hot Plug Detect loop into the TMDS.
Hope this helps.
