I dont know if you guys saw this or not but I thought I'd add to the thread. James has pictures with wiring on his page here:

What James did is wire both Hallmark cycles in "series" or daisy-chaining them together. He connected them to the auxillary 5V DC in the cabinet. Wiring the cycles in series allows for the current to be the same to each cycle. Both cycles are lit continuously.
The other options for running them off the inserts would work if you are a Tron LE owner. The LE's are using LED's for the insert and would keep the power simular ie. 5V DC.
If youre a PRO owner I wouldnt plug into the insert since its 6.3V AC using an incandesent bulb. The Diode's will work but eventually burn out because the higher voltage.
