You only need one switch. Test the original to see if it works and replace or use the toggle. Either way it's just an on-off switch for the fan motor and the wiring is:
1. Wire from the "ON" terminal of the ignition switch to one side of heater switch.
2. Wire from other side of heater switch to motor.
3. Probably a good idea to have an inline fuse between ignition and heater switch. 10 amp.
4. I believe the original switch was a variable resistor type. Increasing speed of motor as you turn knob.
5. I've seen talk of a toggle switch used for the defrost. Probably referring to deluxe vs Standard. Not sure about that info.
The "ON" terminal of the ignition switch is the one that is only hot when ignition is on.
