Okay, you may be stuck there, I'm sure I could walk you through figuring out what would go where but it would seem some interesting rewiring would need to be done. Not absolutely impossible but not a straight forward task either. You would need a multi-meter, and a camera and be somewhat adept at electrical connections and photography. The USB and sound appear to be standard connectors, the power and reset would be the tricky ones (from what I can tell)
BTW, this isn't helpful here but here's a link to your Manuals (guides, supplements, addendums, etc)
