Trying to find where the wire is burnt out cause held it on start too long, where does the wire go after it leaves ignition switch? Up into dash? I'm trying to follow it all the way to the starter

 

Welcome to the forum.

Basically the ignition switch applies power to the starter solenoid which then applies the 12 volts to the starter and to the ignition system. Best thing to do is get a copy of the factory service manual which has the schematics in it.
