1. Planning and Parts:
* Choose your compressor: Research different air compressors designed for air ride systems. Consider factors like CFM (Cubic Feet per Minute), tank size, and noise level. You'll need to select one with sufficient capacity for your intended use.
* Air tank (if not included with the compressor): You'll likely need an air tank to store compressed air. Choose one that's appropriately sized for your system.
* Air lines and fittings: Purchase high-quality air lines, fittings, and potentially a pressure switch and pressure gauge. These need to be compatible with your compressor and tank.
* Mounting brackets and hardware: You'll need to fabricate or purchase brackets to securely mount the compressor and air tank in your Crown Vic. Consider location carefully – you need easy access for maintenance but also need to avoid compromising other components. A common location is in the trunk.
* Wiring harness and relay: The compressor will require a power source. You'll need to run wires to the battery, incorporating a relay to protect the system. Consider using a fuse as well.
* Air ride system itself (if not already installed): This installation assumes you already have an air ride system (bags, lines, etc.) installed. If not, this is a far more complex project.
2. Installation Steps:
* Mount the compressor and tank: Securely mount the compressor and tank using appropriate brackets. Ensure they are well-supported and won't rattle or vibrate excessively. Use vibration dampeners if needed.
* Run air lines: Connect the air lines from the compressor to the air tank and from the tank to the air ride system. Use proper fittings and ensure all connections are airtight.
* Install the pressure switch (if applicable): This will control the compressor's operation, turning it on when pressure drops and off when it reaches the desired level. Wiring this correctly is crucial.
* Wiring: Connect the compressor to a power source via a relay and fuse. This protects the vehicle's electrical system and the compressor itself. Properly grounding the compressor is essential.
* Test the system: Carefully test the system, checking for leaks and ensuring the compressor activates correctly. Monitor the pressure gauge to ensure it operates within safe limits.
* Plumbing (for air ride components): You'll need to connect the air lines from the tank to all the air bags and components in the air suspension system. This requires precise connections and ensuring the system is properly sealed to prevent leaks.
3. Important Considerations:
* Safety: Always disconnect the battery negative terminal before working with electrical components. Use safety glasses and gloves.
* Routing of lines: Route air lines carefully, securing them to avoid rubbing against hot components or moving parts.
* Professional help: If you lack experience with automotive electrical and air systems, it's strongly advised to seek professional help. This project is more challenging than it might initially appear.
* Local regulations: Check local regulations regarding modifications to your vehicle.
This is a general overview. Detailed instructions will vary depending on the specific compressor and air ride system you choose. You should consult the manufacturer's instructions for your specific components. Again, professional installation is highly recommended. Improper installation can lead to significant problems and even safety hazards.
