ignition switch , old sears ....ST 16

Have an older sears ST 16, model 917.25743 . I am in the process of re-wiring the ignition switch and think I have my wires on the wrong terminals. The switch has five terminals coming off of it.
Any help on where I can get a wiring diagram or insight to getting the right wires on the proper terminals would greatly be appreciated.

Thanks ,,,,,,,,,,, Brad
