I need Car Starter Motor Library (schematic only)

I need a car starter motor (schematic only) to complete the electrical wiring. I want to start the motor using 2 channel module relay (1 for switch on/of, another for starter)

The generic motor in core parts is probably your best bet. There likely isn’t a starter motor part otherwise. You also need to look at the current draw (starter motors take a lot of current!) on the relay module. It likely doesn’t have enough current capacity for a starter motor (that is what the started solenoid in a car is for.)
