What is the correct wiring diagram for a 3 wire vs. 4 wire well pump system?

In a 3-wire well pump system, the pump motor is connected to three wires: one for power, one for ground, and one for the start capacitor. In a 4-wire system, an additional wire is used for the start capacitor. The correct wiring diagram will show how to connect these wires to the pump motor and power source for proper operation.
