Furnace Thermostat Wiring I Need A Wiring Diagram To Connect My Furnace To The Thermostat And Its Own Wiring?

I need a wiring diagram to connect my furnace to the thermostat and its own wiring? - furnace thermostat wiring

My "rent" the tenant out of the oven, then turn left, so I handed over the power wiring, but he has a son and does not know which terminal goes - I know not just terminals (two) thermostat cable further. The oven has a "Johnson" label inside outsied but said it was a Magic Chef Model G75 105D-13

Thanks
