They don't display the dots on the coils to be able to confirm the secondary "polarity" but if one were to assume that the dots are on the top of the auto transformers, cylinders 1, 2 and 3 would have the positive induced pulse and coils 4, 5, and 6 would be the return plugs. Now, the confusing part is electrons (current) would actually flow from negative to positive, so that would suggest if what you pasted in post #3 above is accurate, the platinum center electrode plugs should be 4, 5, and 6 and the platinum ground strap should be 1, 2, and 3.
