Multi Interface OBDII to RJ45/USB/DB9P Automotive Diagnostic Harness 1500mm

Fubon Harness is a professional manufacturer that integrates independent mold development, precision wire processing and full-item electrical testing. We focus on developing multi-functional connection solutions for vehicle diagnostic equipment, industrial embedded control and automotive electronic R&D. We have mature production capacity to design complex wiring assemblies, and our rich experience in assembling different connector combinations allows us to produce stable, tailor-made wiring products that meet strict RoHS and automotive industry standards for global diagnostic equipment manufacturers and auto repair enterprises.

This Multi-Interface OBDII to RJ45/USB/DB9P Automotive Diagnostic Harness 1500mm is a comprehensive multi-signal transmission wire specially developed for integrated vehicle detection workstations. Different from single-port extension wires on the market, this product integrates OBD main interface, dual DB9 COM ports, RJ45 network port, Micro USB, DC power socket, CAN/RS485 signal terminals and audio plugs into one set of complete wiring. It adopts UL certified multi-specification stranded wires with color-coded cores, which separate power, CAN bus, analog signal, network and serial communication circuits to avoid signal interference during high-load data reading. The overall finished length is controlled at 1500±30mm, reserving sufficient operating space for bench testing; key soldering positions are wrapped with multi-layer shielding heat shrink tubes and copper foil to enhance anti-interference performance, and laser printed marking tubes are attached to each branch for quick pin identification during maintenance. Every finished product undergoes DC 500V withstand voltage, full continuity and insulation resistance inspection to eliminate hidden dangers such as open circuits, short circuits and signal attenuation.

As a high-performance diagnostic harness, it breaks the limitation of single-channel detection cables, realizing synchronous collection of power supply, CAN bus, serial port and network data at one time. The internal complex branch layout requires standardized grouping and wrapping of dozens of separated wire cores, which puts forward high requirements for production process, and this is where our mature processing technology of collecting multi-wire harness shows its advantages. We adopt layered wire sorting, segmented bundling and secondary shaping processes to ensure the internal wire layout is neat without twisting or extrusion, effectively extending the service life under frequent plugging and bending.

Compared with simple single-interface conversion lines, this integrated assembly can be matched with professional vehicle inspection equipment as a core supporting automotive diagnostic adapter, widely used in ECU flashing programming, whole vehicle signal waveform capture, new energy vehicle on-board system debugging and auto repair shop comprehensive fault detection. Our engineering team can adjust wire length, wire gauge, terminal plating and interface collocation according to customers’ equipment layout and testing logic. This multi-port integrated diagnostic wire has obtained stable repeated orders from automotive electronic laboratories and professional diagnostic tool brands, and we provide flexible small-batch sample service for customers to verify signal compatibility before mass production.
