The OBDII-16 female connector to ECU plug cable, integrated with a 36P+91P+94P multi-pin configuration and an in-line switch, stands as a critical component for automotive diagnostic and electronic control system testing. With a length of 1000mm (1 meter), this high-precision cable is engineered to establish reliable signal transmission between OBDII-compliant vehicles and ECU (Electronic Control Unit) modules, catering to the complex connectivity needs of professional automotive technicians, repair shops, and aftermarket modification specialists.
At the core of its design is the OBDII-16 female connector, which adheres to the universal OBDII standard—ensuring compatibility with most passenger cars, light trucks, and commercial vehicles manufactured after 1996 (in the U.S.) and 2001 (in the EU). This connector features 16 gold-plated pins that minimize signal loss and resist corrosion, guaranteeing stable data exchange even in harsh workshop environments. On the opposite end, the cable terminates in three ECU plugs (36P, 91P, and 94P), covering a wide range of ECU models from major automotive brands. This multi-pin setup eliminates the need for multiple single-interface cables, streamlining diagnostic workflows and reducing equipment clutter.
A key highlight of this cable is the integrated in-line switch, which allows technicians to manually control the signal path between the OBDII port and the ECU modules. This function is invaluable for scenarios such as ECU reflashing, sensor calibration, and fault code troubleshooting—enabling users to isolate specific ECU components or switch between different control units without disconnecting the cable. The switch is designed with a durable, tactile mechanism that provides clear feedback, ensuring precise operation even with gloved hands.
Constructed with premium materials, the 1000mm cable features a thick, abrasion-resistant PVC jacket that protects the internal wiring from physical damage, oil, and moisture. The internal conductors are made of oxygen-free copper, which offers excellent electrical conductivity and reduces signal interference—critical for transmitting high-speed data between the OBDII port and ECU. The cable’s length balances maneuverability and stability: long enough to allow technicians to operate diagnostic tools comfortably without straining the connection, yet short enough to avoid tangling or excessive slack in tight under-hood spaces.
This versatile cable finds applications across various automotive maintenance tasks, including engine performance testing, emission system diagnostics, and ECU software updates. It is also compatible with a range of diagnostic tools, such as OBD scanners, oscilloscopes, and ECU programming devices. Whether used in professional repair facilities or for DIY automotive projects, the OBDII-16 female to 36P+91P+94P ECU switch cable delivers consistent performance, durability, and ease of use—making it an essential tool for anyone working with modern automotive electronic systems.
