Central locking is a system that allows the simultaneous locking or unlocking of all doors in a car using a remote or switch. A central locking actuator is the motor that powers the system, and it works by moving the locking mechanism. Here, we will discuss the wiring diagram for a 5 wire central locking actuator, which is commonly used in many vehicles.
What is a Central Locking Actuator?
A central locking actuator is an electrical motor that enables the locking and unlocking of car doors in one go. The actuator is connected to the car’s central locking system, and it transmits power to all the doors, locking and unlocking them in unison.
The central locking actuator is usually located inside the car door or the trunk, and it is connected to the car’s electrical system. The actuator consists of a motor, a gearbox, and a set of gears that move the locking mechanism inside the door.
How Does a Central Locking Actuator Work?
The central locking actuator works by receiving a signal from the car’s central locking system. The signal is usually sent using a remote or a switch located inside the car. When the signal is received, the actuator motor starts rotating, which moves the gears inside the gearbox. The gears then move the locking mechanism, and the doors lock or unlock accordingly.
The central locking actuator is powered by the car’s electrical system, which provides the necessary voltage to operate the motor.
Wiring Diagram for 5 Wire Central Locking Actuator
The wiring diagram for a 5 wire central locking actuator consists of five wires, each representing a different function. These wires are as follows:
- Positive (Red or Yellow)
- Negative (Black or Brown)
- Lock signal (Green or Blue)
- Unlock signal (Purple or Grey)
- Common ground (White or Orange)
The wiring diagram is as follows:
| Wire | Color | Function |
|---|---|---|
| 1 | Red/Yellow | Positive |
| 2 | Black/Brown | Negative |
| 3 | Green/Blue | Lock signal |
| 4 | Purple/Grey | Unlock signal |
| 5 | White/Orange | Common ground |
Installation of 5 Wire Central Locking Actuator
Installation of a 5 wire central locking actuator requires careful attention to detail. The following steps will guide you through the installation process:
Step 1: Plan the Wiring
The first step is to plan the wiring. Ensure that you have all the necessary components and tools for the installation, including the central locking actuator, wiring harness, relays, fuses, and connectors. Plan the wiring so that it is neat, organized, and easy to troubleshoot.
Step 2: Install the Actuator
Install the central locking actuator in the car door or trunk, as per the manufacturer’s instructions. Ensure that the actuator is securely mounted and that the gears are in good working condition.
Step 3: Connect the Wiring
Connect the wiring harness to the central locking actuator, ensuring that the wiring is properly secured and insulated. Connect the positive and negative wires to the battery, and the lock and unlock signals to the central locking system. Connect the common ground wire to the car’s chassis.
Step 4: Test the System
Test the central locking system to ensure that it is working correctly. Use the remote or switch to lock and unlock the doors. If the system is not working correctly, troubleshoot the wiring and connections until the issue is resolved.
