Shenzhen Fubang Wire Harness Co., Ltd. is a specialized manufacturer concentrating on automotive diagnostic wiring and on-board interconnect cables. We integrate precision injection molding, automatic wire processing and comprehensive electrical performance testing to deliver reliable wiring accessories for global auto repair workshops, diagnostic equipment brands and vehicle aftermarket suppliers. We continuously optimize cable shielding and strain relief craftsmanship to produce stable vehicle diagnostic OBDII cable that adapts to various vehicle maintenance scenarios, and all raw materials conform to RoHS standards to meet international automotive aftermarket access requirements.
This OBDII 16Pin Male to Male Diagnostic Extension Cable is a dedicated extension solution for vehicle fault diagnosis equipment. Unlike short jump wires that limit operation space, this harness adopts dual-sided J1962 OBD male connectors with yellow reinforced shells, which effectively extends the connection distance between diagnostic scanners and vehicle OBD ports. It works as a practical OBD diagnostic adapter, allowing technicians to place testing devices outside cramped engine bays or confined cockpit spaces without frequently plugging and unplugging vehicle sockets.
The internal structure adopts multi-core composite tinned copper cables built with aluminum foil shielding layers, which suppress external electromagnetic interference from vehicle ECUs and ignition systems, ensuring continuous and stable data communication during ECU parameter reading and fault code scanning. The thickened black PVC outer jacket offers excellent anti-abrasion and anti-aging performance, suitable for long-term use in complex maintenance environments. Injection molded integrated strain relief at both connector ends prevents core wire breakage caused by frequent bending and pulling. Our engineering team can adjust cable length, shell color and internal wire layout according to equipment specifications to create customized car diagnostic cable for different scanner models.

Every finished cable passes DC 300V withstand voltage test and full continuity inspection before delivery. All nickel-plated contact pins undergo strict plug-and-pull life testing to maintain stable conduction after thousands of connection cycles. Built-in stainless steel spring clips ensure tight locking after insertion, avoiding accidental disconnection that leads to interrupted diagnostic data. Color-coded internal wiring strictly follows standard OBD pin definitions, facilitating maintenance and circuit inspection.
This OBD extension cable boasts wide applicability in vehicle after-sales service. It is widely used for passenger car and light commercial vehicle fault diagnosis, ECU programming, emission testing and vehicle monitoring equipment connection. As a mainstream extension variant of our complete series of vehicle diagnostic OBDII cable, it can be matched with various OBD split harnesses and diagnostic adapters to form complete testing kits. As an easy-to-use passive OBD diagnostic adapter, it greatly improves the operation flexibility of maintenance personnel, and we can further optimize shielding structure and mechanical durability to provide high-performance car diagnostic cable solutions for professional diagnostic equipment manufacturers.
