This ignition switch (08) has the same function as yours. Numbering is per photo. No number on my switch that can be seen. Terminal 1 - There should be 12v to this terminal all the time. Terminal 2 - 12v when ignition turned on and also when turned to accessory. Terminal 3 - 12v when ignition turned on. Terminal 4 - When key is turned to crank engine this terminal gets 12v ( starter motor relay )
