Here is what I could come up with from my personal pics. You can't see the WOT switch too well, but you should be able to get the drift.
Use the bracket that comes with the WOT switch. Run the bottom right TB bolt through the bracket and then bend into position. Make sure the dog ear on the TB (circle A), hits the switch (circle B) only when the butterflies are ALL THE WAY open. Its really a trial and error thing. There is no "wrong" way to mount it. As long as the switch is down when the TB is wide open.
Let me know if you have anymore questions.
