Answer how to connect the four wires of the car's main lock and how to connect the four wires on the plug of the left front door lock

What are the four wires of the car's main lock and how to connect them?

Two are the control lines of the locking motor, and two are the control lines of the locking trigger. The additional anti-theft device is connected to the two trigger lines.

The four-wire central control does not have a motor, and a separate unlocker is required. The CIF has its own motor. However, there are many types of unlocking machines equipped with Jetta, which can not be distinguished by just looking at the line. Four wires with motors have two fires and two grounds, but the color is not necessarily dependent on the batch. Generally brown is the ground wire, red, red and white, red and black, red and yellow can be power supply, and the other black and white or black, black and yellow Colors such as, green and so on are auxiliary wires. To put it bluntly, it is the corresponding live wire or ground wire when the power supply is turned over.

What are the four wires on the plug of the left front door latch?

One side belongs to two motor wires, and the other is two signal wires.

In the example on the left, two of the four wires of the door locker are the left front door locker control wires, and the other two wires control the other three doors, because the left front door is the main control and can control other doors.
