I haven't found anything about what the switch cuts power to when in crank position. If you have a link it would be most helpful.
In the OFF position there is no connection between any of the terminals.

In the ON / RUN position, the BAT (red wire), IGN (pink wire), and ACC (brown, brown w/white stripe wire) are all connected together. There is no connection to the SOL (purple wire) or the GRD 1 & GRD 2 (green & tan wire) terminals in this position.

In the CRANK / START position, the BAT (red wire), IGN (pink wire), and SOL (purple wire) terminals are all connected together. There is no connection to the ACC (brown, brown w/white stripe wire) terminal. The GRD 1 & GRD 2 terminals are connected to ground via the switch's metal case. That serves to provide a "bulb check" feature for the TEMP & BRAKE warning lights on the dash.
