@OP - your connections were correct before the change. The guitar should be on the left.
There is no absolutely foolproof way just from recordings to know whether the channels are connected correctly - except to use a channel identification test disc.
However, in the majority of rock and pop recordings, hi hats will be panned right of centre as you face the system. That is the perspective you would have if you were looking at a right handed drummer at a live gig. Exceptions to that presentation are pretty rare.
Great album, Midnight Blue btw.
