Apexi Turbo Timer Wiring Diagram

The Apex turbo timer is a valuable aftermarket component designed to prolong the life of a turbocharged engine. By allowing the engine to idle for a pre-set period after the ignition is turned off, it ensures proper oil circulation and cooling, preventing oil coking and turbocharger damage. Understanding the Apex turbo timer wiring diagram is crucial for a successful and safe installation.

Benefits and Purpose of an Apex Turbo Timer

Installing an Apex turbo timer offers several key benefits:

• Extends Turbocharger Life: Prevents oil coking in the turbocharger bearings due to excessive heat after engine shutdown.
• Reduces Oil Degradation: Allows for proper oil cooling, reducing breakdown and improving lubrication.
• Convenience: Automatically manages the cool-down period, allowing the driver to remove the key and leave the vehicle running safely.
• Security Features: Many Apex turbo timers include security features like parking brake interlock and ignition cut-off to prevent theft.

Understanding the Apex Turbo Timer Wiring Diagram

A typical Apex turbo timer wiring diagram will include connections for:

• Power (12V): Connected to a constant 12V source.
• Ground: Connected to a reliable ground point.
• Ignition: Connected to the ignition wire, which is energized when the ignition is on.
• Accessory: Connected to the accessory wire, which is energized when the key is in the accessory or on position.
• Starter: Wired in series with the starter circuit to allow the timer to control the starter.
• Parking Brake: Connects to the parking brake switch for enhanced security (optional).

Carefully study the specific Apex turbo timer wiring diagram included with your unit. Colors may vary across different models, and incorrect wiring can damage the timer, the vehicle’s electrical system, or both.

Practical Application

Before beginning installation, disconnect the negative terminal of the battery. This is a crucial safety step. Follow these general steps:

1. Locate Wires: Use a multimeter to identify the correct ignition, accessory, and starter wires.
2. Connect Power and Ground: Ensure secure and reliable connections to the 12V source and ground.
3. Connect Ignition and Accessory: Splice into the ignition and accessory wires according to the diagram.
4. Connect Starter Wire: Cut the starter wire and connect both ends to the turbo timer’s starter circuit wires. This allows the timer to interrupt the starter when active.
5. Parking Brake Connection (Optional): Connect the parking brake wire to the parking brake switch if desired.
6. Test: Reconnect the battery and test the functionality of the turbo timer, including the cool-down timer and security features.

1. Troubleshooting Common Issues

Here are some common issues encountered during installation:

• Timer Not Powering On: Check the power and ground connections, and the fuse.
• Engine Not Starting: Verify the starter wire connections and ensure the timer is not in cool-down mode.
• Incorrect Cool-Down Time: Refer to the timer’s settings and adjust the cool-down time as needed.

2. Tips for a Successful Installation

• Use Quality Connectors: Avoid using cheap connectors that can corrode or come loose. Solder connections where possible.
• Protect Wiring: Use electrical tape or heat shrink tubing to protect the wiring from damage.
• Double-Check Connections: Verify all connections before reconnecting the battery.
• Consult a Professional: If you are unsure about any aspect of the installation, consult a qualified automotive electrician.
