Original Starter Wiring
 

I have a 1994 Cherokee that the previous owner bypassed the stock wiring to the starter / fuses and tapped directly into the wire from under the dash (I assume the ignition start wire) and wired directly to the starter solenoid. This obviously bypassed the Safety Neutral switch. It starts in any gear now. Can anyone help me get this back to normal so I can run it through the SNS? Where does the solenoid wire to the starter come from. I can't find anything that was disconnected previously. I'm not sure why they bypassed it in the first place.
Thanks
