boy, i'll say.
pinouts, Peerless gave them out with the enclosed data sheets, but not in the catalog, at least not mine.
you can get the pin numbers off a schematic, if you can find one.
should be 4 identical coils, ohm it, then right down the pairs, put it on a scope to phase and your done.
i doubt there will be much difference running the hots backwards, everything should be balanced in a 600:600 1:1 line in.
