Figs,
The Gemini AP wires EXACTLY like the Vizion. There are slight differences between your ADI Pilot II (and the Digiflight II series), but these are all taken care of by the included adapter harness that we provide with all upgrades. The only other issue that you might see would be that the mounting screw holes aren't exactly the same as the ADI Pilot II. The Gemini AP follows the standard 3-1/8" instrument mounting pattern and the ADI Pilot II was slightly different in the lower portion due to the knobs. I think that you will be in pretty good shape! If you pitot / static lines are short, then you might also have to lengthen those slightly because the Gemini AP is so much thinner than the ADI Pilot II.
Lucas will surely correct me if I made any stupid mistakes in what I wrote above...that's why
