- Hood Pin: Another safety feature that prevents starting if the hood is open.
Example: For a 2018 Honda Accord, you might need to identify the ignition 1 wire at the steering column harness. A wiring diagram might indicate this as a purple wire. Using your multimeter, you would confirm it has 12V when the ignition is on and 0V when off. This methodical approach is vital for every connection.
Safety First: Disconnecting the Battery
Before you begin any electrical work, it is absolutely imperative to disconnect the negative terminal of your car battery. This prevents accidental shorts and protects you from electric shock. Locate your battery (usually under the hood) and use a wrench to loosen the clamp on the negative terminal. Gently pull the cable off the terminal and secure it so it cannot accidentally touch the battery post.
Step-by-Step Installation Process
This section will guide you through the physical installation of the remote start system. Remember to consult your specific kit’s instructions and your Honda Accord’s wiring diagram throughout this process.
Step 1: Accessing the Steering Column and Dashboard Components
You’ll need to remove various plastic panels around the steering column and dashboard to access the necessary wiring. This often involves:
- Removing Lower Dashboard Panels: Typically, there are a few screws or clips holding these in place. Use your trim removal tools carefully to avoid scratching or breaking the plastic.
- Lower Steering Column Covers: These usually have screws that need to be removed.
- Upper Steering Column Shroud: Once the lower covers are off, you’ll have access to the screws holding the upper shroud.
Take your time and organize the removed screws and panels. Labeling them or taking pictures can be incredibly helpful for reassembly.
Step 2: Locating and Identifying Key Wires
With the panels removed, you’ll have access to the wiring harnesses. This is where your wiring diagram and multimeter are essential. Systematically identify and test each wire required by your remote start system. Be methodical and double-check your findings.
Example: When searching for the 12V constant wire, you might find a thick red wire in the ignition harness. Using your multimeter set to DC voltage, touch one probe to the wire and the other to a known ground (like a bare metal part of the chassis). If you read approximately 12V, you’ve likely found your constant power. Then, test the ignition wires by turning the key to the “on” and “accessory” positions.
Step 3: Connecting the Remote Start Control Module and Bypass Module
This is where you’ll start making connections. Your remote start kit will come with a main control module and, for most modern cars, a separate bypass module. The bypass module is crucial for overcoming your Honda Accord’s factory immobilizer system.
T-Harnesses vs. Direct Wiring:
- T-Harnesses: Some premium kits come with vehicle-specific T-harnesses. These plug directly into your car’s existing connectors, eliminating the need to cut and splice into factory wires. This significantly simplifies installation and reduces the risk of errors.
- Direct Wiring: If T-harnesses aren’t available, you’ll need to make secure connections to the identified wires. This is typically done using crimp connectors or by soldering and then insulating with heat shrink tubing or high-quality electrical tape.
Follow your remote start kit’s wiring diagram precisely. Connect the control module to the bypass module, and then connect both to the appropriate wires in your Honda Accord’s wiring harness. Ensure all connections are secure and properly insulated.
Step 4: Installing Safety Features (Brake Switch, Hood Pin)
These safety features are non-negotiable. They prevent accidental activation of the remote start system.
- Brake Switch Connection: Locate the brake light switch (usually above the brake pedal). You’ll need to tap into its wire to signal the remote start module when the brake is pressed.
- Hood Pin Installation: This involves mounting a small switch on the underside of the hood so that it is depressed when the hood is closed and released when the hood is open. You’ll then connect this switch to the remote start module.
These connections are vital for safe operation and preventing potential accidents. Without them, your car could potentially try to start while in gear, which is extremely dangerous.
Step 5: Routing and Securing Wires
Once all the electrical connections are made, you need to neatly route and secure the wiring. This prevents wires from getting snagged on moving parts, dangling loosely, or creating a fire hazard.
- Use Zip Ties: Bundle wires together and secure them to existing factory looms or solid structural points in the vehicle’s chassis.
- Avoid Moving Parts: Ensure no wires are routed near steering components, pedals, or exhaust systems.
- Protect from Pinching: Be careful not to route wires where they can be pinched by reinstalled panels.
A clean and organized wiring job not only looks better but also makes troubleshooting and future maintenance much easier.
Step 6: Reassembly and Testing
With all wiring complete and secured, it’s time to reassemble the interior panels. Work in reverse order of disassembly, ensuring all screws and clips are properly reinserted.
Before reconnecting the battery, double-check all your connections one last time. Once you’re confident, reconnect the negative battery terminal.
Testing the Remote Start System:
