Cruise control is a system that automatically controls the speed of a motor vehicle, providing a more relaxed driving experience on long journeys by maintaining a steady speed set by the driver. It’s a feature commonly found in new vehicles, but many drivers with older or base model cars without this function often wonder if they can upgrade their vehicles to include it. The answer is yes; aftermarket cruise control kits are available to bring this convenience to cars that didn’t come with factory-installed cruise control.
These aftermarket solutions range from basic models to sophisticated systems that can integrate with modern vehicle electronics. The installation process will vary depending on the type of car and the complexity of the kit. A typical installation involves placing an actuator in the engine compartment, routing a wiring harness, and possibly mounting a control switch on the dashboard or steering column. Professional installation might be recommended for more complex systems, particularly those that interface with drive-by-wire systems as opposed to older throttle cable setups. It’s also worth noting that adding an aftermarket cruise control system should be done with careful consideration to ensure compatibility with your vehicle’s specific make and model.

Choosing the Right Cruise Control Kit
When upgrading your vehicle with an aftermarket cruise control kit, it’s crucial to select one that is compatible with your specific car and to understand the installation process involved.
Compatibility with Your Vehicle
Assessing Installation Complexity
Keep in mind that some vehicles may have unique requirements or installation challenges. If we feel unsure about the installation process, consultation with a professional might be beneficial to avoid any potential issues.
Installation Process Overview
Installing cruise control can significantly improve your driving experience, especially on long journeys. It’s a detailed process requiring specific tools and an understanding of your car’s electronic system.
Gathering the Necessary Tools
Before beginning the installation, it’s essential to gather all the necessary tools. Most cruise control kits will come with a list of required tools, but here’s a basic list to get started:
🔧 Basic Toolkit
- Screwdrivers (both flathead and Phillips)
- Socket set
- Wire stripper
- Crimping tool
- Electrical tape
- Zip ties
- Drill and drill bits
🛠️ Specialized Tools
- Torque wrench
- Multimeter
Understanding Wiring Harness Connections
The next step is to understand how the wiring harness connects to your vehicle’s electronic system. A wiring diagram for your specific car model will be incredibly helpful and is often provided in the installation kit. Locate the wires responsible for throttle control and vehicle speed signals. Incorrect wiring can lead to malfunctions, so pay close attention to this part.
Mounting the Control Switch and Module
Lastly, the control switch and module are critical components that require secure mounting. You’ll often place the control switch on or near the steering wheel for easy access.
-
Control Switch: Mounting here generally involves removing part of the steering column cover and securing the switch. Ensure the switch doesn’t hinder any steering wheel functions.
-
Module: It’s typically installed inside or near the dashboard. Find a location that doesn’t interfere with other components. The module may be placed using pre-existing studs or require drilling new holes for secure mounting.
After installing these components, connect them to the car’s wiring system by following the provided instructions. Check all connections thoroughly before testing the system.
Remember, while we aim for a seamless installation, it’s crucial to cross-check every step and follow safety precautions. If you’re not confident in your ability to install the cruise control system, consulting a professional is a wise decision.
Operational Testing and Troubleshooting
After installing cruise control, it’s crucial to ensure it functions correctly before embarking on a drive. This section will guide us through the operational testing and the troubleshooting process to address any issues that may arise.
Ensuring Optimal Functionality
Functional Check:
Before using the newly installed cruise control system, we conduct a series of tests to confirm its readiness. The process involves the following steps:
- VSS (Vehicle Speed Sensor) Verification: We ensure the VSS is properly connected and sending accurate speed data.
- Throttle Position Sensor (TPS) Check: The TPS should be correctly calibrated, communicating the throttle’s position to the ECU (Engine Control Unit).
- Cruise Actuator Inspection: This actuator manages the throttle’s position when cruise control is active. It must move freely and respond to commands.
- Signal Generator Testing (if applicable): For systems using a signal generator, we verify signal accuracy.
- ECM Operation: The Engine Control Module should be free of errors and in communication with the cruise control system.
- Switch Functionality: We test all cruise control switches for responsive engagement and disengagement.
In vehicles with Adaptive Cruise Control, additional sensors and radar systems require alignment and calibration. These systems must adapt to changing traffic conditions and respond accurately to maintain safety.
Common Installation Errors to Avoid
Here, we identify installation missteps that could lead to poor performance or failure:
Firstly, faulty wiring or loose connectors can disrupt signal flow from sensors to the cruise control unit. Ensuring all electrical connections are secure is paramount. Incorrectly configured components can lead to erratic behavior or non-functional systems.
If a malfunction is detected, troubleshoot by systematically checking each component for faults. Clear error codes from the ECM before and after repairs to avoid misleading information.
To prevent common mistakes:
- Ensure the Cruise Actuator is free of obstruction and securely mounted.
- Align and calibrate Adaptive Cruise Control sensors following the manufacturer’s guidelines.
- Confirm the ECU software is updated to recognize and incorporate the cruise control function.
By paying attention to these critical elements during installation, we significantly reduce the chances of encountering issues later on.
Considerations for Long-Term Use
When incorporating cruise control into our vehicle’s feature set, we prioritize longevity and safety. Keeping these systems in optimal condition ensures reliable performance during long road trips and enhances driving safety.
Maintenance and Safety Tips
Maintenance: Regularly checking the cruise control system for functionality before embarking on long trips is essential. We recommend scheduling inspections with a licensed mechanic who can diagnose and service any potential issues.
Cruise control systems, like any other part of our car, require ongoing attentiveness. Here are critical steps we follow:
| Checklist Item | Action |
| Sensor & Actuator Check | Ensure connections are clean and free of obstruction |
| Speed Setting Responsiveness | Test for accurate engagement and disengagement |
| Throttle Control | Verify smooth acceleration and deceleration |
Understand Warranty and Professional Support
Aftermarket installations of cruise control should always be discussed with our mechanic. Knowledge of the system’s compatibility with our vehicle ensures we maintain the warranty terms.
