I bought this transformer to use on a test rig that I am building. It was taken out of a Sega Rad Mobile machine. I am assuming the yellow and black is the input side but I'm not sure which set of wires to send to the monitor and was wondering if someone here could help.

i would apply power to the black/yellow, then meter the purple/gray, and blue/orange to see what it gives you.
 
from the 3rd pic, looks like yellow / black is the input side (supply) and im guessing the yellow is the neutral. apply supply to that connector and probe the other connector with a dmm on VAC to see what you have there. for the others i would probe with a dmm on VAC one lead on the yellow neutral ( supply side) and then each other wire one at a time to see what V is on each lead out. if it was me thats what i would try anyway.
