What are the four wires of the car's main locking device and how do I connect them?
Two are the control lines of the locking motor, and two are the locking trigger control lines. The anti-theft device is installed by connecting to these two trigger lines.
The four-wire central control does not have a motor and needs a separate unlocker. The CIF has its own motor. However, there are many types of unlockers equipped with Jetta, and they cannot be distinguished by just looking at the wires. The four-wire with motor has two live and two ground wires, but the color is not necessarily, it depends on the batch. Generally, brown is the ground wire, red, red and white, red and black, red and yellow can all be power supply, and the other black and white or black, black and yellow, green and other colors are auxiliary wires, which are the corresponding live wire or ground wire when the power supply is flipped.
What are the four wires on the left front door lock plug?
One side belongs to the two motor lines, and the other is the two signal lines.
Of the four wires of the left door lock, two are control wires for the left front door lock, and the other two are used to control the other three doors. Because the left front door is the main control, it can control the other doors.
