What are the steps for installing a car anti-theft device?

The steps for installing a car anti-theft device are: 1. Remove the cover under the steering wheel and pull out the two brown turn signal wires from the main harness; 2. Take out the original car plug and connect it to the anti-theft device plug, straighten the wires after connecting, then replace the cover and tighten the screws; 3. Connect the door wire, the turn signal wire and the door wire are together, wrap them with tape after connecting and plug the connector back; 4. Connect the iron wire, brake pedal wire, and horn wire; 5. Install the central lock and anti-theft horn. A car anti-theft device is an alarm system installed in a vehicle. If someone hits, impacts, or moves the car, the sensor will send a signal to the controller indicating the vibration intensity. Depending on the intensity of the vibration, the controller will emit a warning sound or trigger a full alarm to deter thieves and alert the owner.

I've installed car alarms myself several times. It's actually quite simple but safety is crucial. First step is turning off the car's power and disconnecting the negative battery terminal to prevent electric shock. Then choose an alarm kit - go for quality over cheap options. When installing the main control box, find a concealed location like under the steering wheel or inside the glove compartment. Wiring is the critical part: connect the red wire to positive power, black wire to ground, and other wires (turn signals, horn wires) according to the manual. Always use a multimeter to check circuit continuity and avoid reversing polarity which could blow fuses. Position the antenna and sensors under doors or hood, ensuring secure fastening. After wiring, reconnect the battery and test remote functions to verify light and horn responses. If issues occur, recheck connections. Finally program the password or sync keys, then neatly organize wiring harnesses to prevent problems. A properly installed alarm not only deters thieves but may also lower insurance premiums.
