Figure 4: Comprehensive wiring diagrams for different vehicle types.
5.2 General Installation Steps
- Disconnect Battery: Before starting, disconnect the vehicle's negative battery terminal.
- Mount Control Box: Choose a secure, dry location inside the vehicle (e.g., behind the dashboard) to mount the control box.
- Connect Power: Connect the main power wire (usually red) to a constant 12V power source. Connect the ground wire (usually black) to a suitable chassis ground point.
- Connect Central Locking Wires: Identify your vehicle's central locking system type and connect the corresponding wires from the control box to the vehicle's wiring harness as per the diagram.
- Connect Indicator Lights: Connect the wires for the direction light flashes to your vehicle's turn signal circuits.
- Connect Trunk Release (Optional): If your vehicle supports remote trunk release, connect the trunk release wire from the control box to the vehicle's trunk solenoid circuit. A relay may be required for this connection (not included).
- Connect Siren Output (Optional): If using an external siren, connect the siren output wire.
- Test Connections: Reconnect the battery and test all functions (lock, unlock, trunk release, indicator flashes) using the remote controls.

7. Maintenance
- Remote Battery Replacement: If the remote control range decreases or the LED indicator on the remote does not light up, replace the battery (typically a CR2016 or similar coin cell battery).
- Keep Dry: Ensure the control box and remote controls are kept dry and away from extreme temperatures.
- Wiring Inspection: Periodically check wiring connections for any signs of wear, corrosion, or looseness.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| System does not respond to remote. | Dead remote battery, out of range, faulty wiring. | Replace remote battery. Move closer to the vehicle. Check power and ground connections to the control box. |
| Doors do not lock/unlock. | Incorrect central locking wiring, faulty door actuators. | Verify central locking wire connections against the diagram. Test vehicle's door actuators independently. |
| Direction lights do not flash. | Incorrect light wiring, blown fuse. | Check connections to vehicle's turn signal circuits. Inspect the fuse in the wiring harness. |
| Trunk release does not work. | Incorrect trunk release wiring, missing relay, faulty trunk solenoid. | Ensure trunk release wire is correctly connected and a relay is used if necessary. Test vehicle's trunk solenoid. |
