Understanding the intricacies of your classic automobile is key to its longevity and your enjoyment. For owners of the iconic 1968 Mustang, a crucial, yet often overlooked, component is the neutral safety switch. This article will delve into the 1968 Mustang Neutral Safety Switch Wiring Diagram, explaining its function and how it contributes to the safe operation of your beloved pony car.
The Role and Function of the 1968 Mustang Neutral Safety Switch
The 1968 Mustang Neutral Safety Switch, often referred to as the "Park/Neutral Position Switch" or "Clutch Pedal Position Switch" depending on transmission type, serves a vital safety purpose. Its primary function is to prevent the engine from starting unless the transmission is in either the Park or Neutral position (for automatic transmissions) or the clutch pedal is fully depressed (for manual transmissions). This simple yet ingenious device is wired directly into the starter circuit, acting as a gatekeeper to unwanted engine crank-overs. This safety feature is paramount in preventing accidental vehicle movement while the engine is being started.
The wiring of the 1968 Mustang Neutral Safety Switch is designed to interrupt the flow of power to the starter solenoid. For automatic transmissions, the switch typically has two main functions:
- Neutral Start: When the shifter is in Neutral, the switch completes a circuit, allowing power to reach the starter.
- Park Start: Similarly, when the shifter is in Park, the switch also completes the circuit.
If the shifter is in any other gear (Drive, Reverse, etc.), the switch is positioned to break this circuit, thereby disabling the starter. For models equipped with a manual transmission, a similar switch is activated by the clutch pedal. When the clutch pedal is not pressed, the switch is open, and the starter cannot engage. Only when the clutch pedal is fully depressed does the switch close, allowing the starter to crank the engine.
Here's a simplified look at the general wiring principle (specific wire colors may vary by production date and options):
| Component | Connection Point | Function |
|---|---|---|
| Battery (through ignition switch) | One side of the neutral safety switch | Provides power when the ignition is turned to START |
| Neutral Safety Switch | Other side | Completes or breaks the circuit to the starter solenoid |
| Starter Solenoid | Connects to the switch's output | Engages the starter motor when the circuit is complete |
Understanding this basic flow helps in diagnosing starting issues and ensuring your Mustang remains a safe classic to operate.
