Replacing original ignition switch with aftermarket one. Looking for wiring diagram. I don't know where the blue/black stripe wire from the glow plug solenoid relay goes on the ignition switch? Battery, Starter, Ignition or Accessory?

Your original switch had a point all the way left for glow plug heater, you will have too add a momentary switch to heat plugs and go off the on or accessories side to work.
 
Here's a wiring diagram from the manual. Not sure what S/N you have but here's one for earlier 743's. I got the manual from truckmanualshub.com for free. No complaints so far. Linked here. https://truckmanualshub.com/bobcat-pdf-workshop-manuals/

PS: Do you have a cab heater in yours? Having issues with mine.

This is the old switch on my 643. Was faulty (didn't engage the glow plug relay) and I replaced it with a new aftermarket one. Worked like a charm! Good luck!
