The wiring harness of the car seat suction-type wireless charger is a key component that connects the wireless charging module to the vehicle's power supply, responsible for transmitting electrical energy and ensuring stable charging. The following introduces it from aspects such as the wiring harness structure, installation key points, and precautions.
Cable Structure and Function: The cable usually consists of power input cables and signal connection cables. The power input cables include positive (red) and negative (black) wires, which need to be correctly connected to the corresponding terminals of the vehicle cigarette lighter or fuse box to prevent short circuits or equipment damage; the signal connection cables may involve control circuits, but the specific configuration varies depending on the vehicle model and charger model. The internal wires of the cable generally use 20AWG electronic wires to balance current carrying capacity and flexibility. The outside is wrapped with insulating material and wrapped with tape to reduce abnormal noise.

The automotive seat wiring harness is an electrical connection system integrated within the seat, responsible for transmitting power and signals and enabling the realization of various functions.

Main functions and composition:
The seat wiring harness typically includes the following functional modules:
Electric adjustment control cable: This is used to control the forward and backward movement of the seat, the elevation adjustment, and the reclining angle of the backrest, in order to meet the comfort requirements of different drivers and passengers.
Safety-related circuits: These include the airbag activation circuits, seat belt alert system circuits, and seat weight sensor circuits, ensuring that the airbags deploy promptly in the event of a collision and monitoring the status of the seat belts and the weight of the occupants.
Comfort function lines: Such as seat heating, seat ventilation, etc., enhance the riding experience through built-in electric heating wires or fans, etc.

The car microphone wiring harness is a crucial component of the in-car hands-free system, responsible for transmitting audio signals, power, and grounding connections, ensuring clear communication.

The physical connections of the wiring harness usually involve multi-pin interfaces. For example, in a 28-pin interface, specific pins correspond to the functions of the microphone. Pin 4 is connected to the red signal line (positive terminal of the microphone signal), pin 5 is connected to the white wire (possibly a backup or differential signal line), pin 6 is connected to the yellow wire (possibly used for power or ground), and pin 19 is connected to the black wire (usually ground). The actual definitions need to be confirmed through measurement with a multimeter, as there may be significant differences among different vehicle models.

The electric tailgate wiring harness is the core component for achieving automatic opening and closing of the tailgate as well as for safety control. It is responsible for power distribution, signal transmission and data communication.
The wiring harness is mainly composed of power lines, signal lines and grounding lines. It usually contains multiple wires of different specifications. For example, the original factory electric tailgate switch may include yellow-green wires (ground wire), white wires (power positive wire) and brown-gray wires (positive wire of indicator light). While the added system may need to connect more lines to meet the functional requirements.
The wiring harness needs to handle a high power output. Some of the original factory circuits use wires with an area of 3 square millimeters to ensure stable current.

The automotive electric pedal wiring harness is a crucial component that connects the electric pedal to the vehicle's electrical system, responsible for transmitting power and signals to ensure the normal operation of the pedal's automatic extension, retraction, and position control functions. The following provides an introduction from the aspects of composition, function, connection method, maintenance standards, and model-specificities.
The electric pedal wiring harness is mainly divided into low-voltage wiring harness and high-voltage wiring harness. The low-voltage wiring harness covers the wiring in the engine, front compartment, chassis, etc., including power lines, grounding lines, signal lines, and fault indication lines, etc. For example, the power line provides power to the pedal, the grounding line ensures stable current return, the signal line transmits the pedal position information to the control unit, and the fault indication line is used to monitor sensor abnormalities. The high-voltage wiring harness involves the vehicle power system and must strictly follow safety regulations.

The microphone cable is a dedicated audio transmission cable that connects the microphone to the audio equipment. It is used to transmit weak audio signals, and its core design focuses on shielding performance to reduce external interference.
Basic Structure and Function: The microphone cable usually consists of a sheath, a shielding layer, an insulating layer, and a conductor. The sheath is the outermost layer and must have elasticity, softness, and dirt resistance; the shielding layer is made by methods such as copper wire weaving and aluminum foil isolation to prevent electromagnetic interference; the conductor is responsible for signal transmission and is typically made of tin-plated oxygen-free copper to reduce resistance and attenuation.

Shielding methods and selection: Common shielding methods include wrapping copper wire (suitable for short distances, but prone to poor shielding when bent), braided copper wire (good shielding effect, strong tensile strength, suitable for mobile devices), aluminum foil isolation (full coverage shielding, but the effect declines after repeated bending, mostly used for fixed installations), and composite isolation (such as aluminum foil + braiding, used in high interference environments). When choosing, it is necessary to balance the shielding effect, flexibility, and durability according to the usage scenario.
