What is a Door wire Harness?
Door Wire Harness is a set of cable and connector assemblies installed in the interior of automobile doors. Its main function is to connect the various electronic functions inside the door to the main body control system. It is an indispensable connection bridge in modern automotive electronic system through a bundle of organized wires to communicate and supply power to the various electrical devices on the door and the body control module.
Door wiring harness belongs to the key components of high-frequency action area in the wiring of the whole car, which is one of the core factors to decide whether the electronic function of the door operates normally or not. It is one of the core factors determining the normal operation of the door electronics function. In the maintenance, modification or vehicle development stage, it is crucial to choose a reliable and accurately matched door wiring harness.
Components & Features of Door Wiring Harnesses
Although the door wiring harness seems to be a bunch of wires, it is actually a highly integrated and complex electrical connection system. It must undertake a variety of functional signal transmission tasks in a limited space, and at the same time to meet the folding resistance, waterproof, shockproof and other harsh conditions of use. The following are typical components of a car door wiring harness:
- Wires / Cables
- Terminals
- Connectors
- Protective Sleeving
- Grommets & Seals
- Labels & Clips
- Optional Brackets
Typical Functions of a Car Door Wire Harness
Door wiring harness is one of the most complex and critical subsystem harnesses in modern automotive electronic systems. It not only needs to complete the electrical connection, but also to realize multifunctional synergy, safety control, comfort configuration and other tasks. In mid-range and high-end models, there are more and more electronic functions in the door, and the functional requirements for the wiring harness are also getting higher and higher.
Power Window Control
The door wiring harness connects the window lift motor with the central control module. It can realize the power and signal transmission of window switch button and control the glass lifting action.
Central Locking System
Connects the door lock motor through the wiring harness. It realizes the functions of automatic door unlocking, remote unlocking and child locking.
Courtesy / Ambient Lighting
Power and control signal transmission channel for the lighting system at the bottom of the door. Commonly used to light up the welcome light or door ambient light when the door is opened.
Speaker / Audio Wiring
The audio signal cable that connects the door audio unit to the host system. Including mid-woofer, tweeter, etc.
Mirror Adjustment
Supports power rearview mirror adjustment, heating, folding, memory function and so on. Some wiring harnesses also integrate turn signal wires or reverse mirror camera power.
Side Airbag Wiring
Used to connect the airbag module mounted on the side of the door or seat. Responsible for transmitting trigger signals and status monitoring, it is a key passive safety control channel.
Keyless Entry / Sensor
The door handle sensor module cable is integrated in the door wiring harness of high end models, supporting intelligent control such as proximity unlocking and touch locking doors.
Child Lock / Unlock Signals
Connect to the body control system. Realize functions such as automatic unlocking after an accident and remote control of child safety locks.

FAQs about Linkwings Door Wire Harness
How do I know which door wiring harness fits my model?
You can quickly confirm the wiring harness model you need by providing the model, year, door position (left front/right rear, etc.) and the original OE number. If you have a sample of the original wiring harness in hand, you can also take photos or send samples to us directly, so that our engineers can carry out terminal alignment, length comparison and function channel confirmation.
For modification projects or functional upgrades, we also support customized harness structures according to drawings, function points or customer requirements.
Is your wiring harness the same as the stock one? Do the plugs go right in?
The replacement wiring harness we provide adopts the same or equivalent plug structure, terminal specification and wiring color coding as the original, supporting plug and play without additional modification or cutting. If you provide us with the OE number or original samples, we can restore 100% of the original connector to ensure smooth installation and functional compatibility.
In some high-specification or special models, if there is a difference in function (e.g. missing airbag or ambient light interface), we will also remind you in advance and assist in adjusting the program.
Can I customize my door wiring harness? What can be customized?
Of course. We support the whole process of customization from functional structure to label packaging, specifically including:
- Wire color, length, quantity
- Plug brand/model (e.g. TE, JST, Molex, Sumitomo)
- Bellows, waterproof construction, tie design
- Additional function channels (e.g. heated mirrors, power folding, ambient lighting, power supply, etc.)
- Customer labels, QR codes, box stickers, serial number management, etc.
Is technical support and installation drawings available?
Can. We provide clear wiring diagrams, plug pin definitions, drawings of harness wiring recommendations, and video installation instructions where necessary. For customized harnesses, complete packages of 2D structural drawings, 3D assembly references, label lists, plug numbering instructions, and more are available to assist customers with efficient installation and maintenance.
