I could send you photos of my modified one. The transformer wires would be in the same locations for the most part. I actually made a layout of my 200S before I modified it, and then another one after I finished it. I don't have a scanner however, so I'd have to photocopy it and mail it to you. And then you'd have to be able to intrepret how I drew the layout! Haha. But I'd be happy to help you out that way if you can't find any pics yourself.
Try looking on ebay for pics as when they sell them there, they often have pics of the inside. You coudl also look at pics of a sorado, sonic 1, sonic 2, and some other models which are very similar to the 200S.
