Light Central Controller Assembly 3714120AAO1C For FAW Truck Spare Parts

 3714120AAO1C is one of the core brains of the electrical system of Jiefang trucks, specifically used to centrally control and distribute the lighting signals of the entire vehicle. In the heavy-duty truck circuit, it replaces the traditional dense array of relays and fuses, intelligently managing all the vehicle's lights through an integrated circuit board, and providing overload and short-circuit protection functions. It is a very critical and common electrical wear-prone component on the Jiefang J6 model.

Product Features

This product adopts a centralized electrical control design. It integrates the control functions of multiple lighting circuits, including headlights, turn signals, fog lights, and taillights, into a single module. This simplifies the wiring structure inside the cab and on the vehicle body, reducing the failure rate of wiring nodes.

The internal circuitry integrates overload and short-circuit protection units. When an external light fixture or a local wiring circuit experiences an abnormal short circuit, the controller reacts quickly and automatically cuts off the power to that circuit. This effectively prevents electrical fires and ensures the overall electrical safety of the vehicle.

The housing is made of high-strength flame-retardant engineering plastic. The product has excellent sealing properties, is shock-resistant, moisture-proof, and dustproof. It can withstand long-distance, bumpy truck transportation and harsh working environments such as construction sites and mining areas.

The product is developed strictly according to standard component interfaces. The terminal blocks are the same size as the original vehicle wiring harness plugs. This enables plug-and-play functionality, allowing maintenance personnel to quickly complete replacements and effectively shortening vehicle downtime for maintenance.
