DB25 Male Splitter OBD Diagnostic Wiring Harness
DB25 Male Connector for Multi-Branch Diagnostic Connections
When a test setup needs to connect several wiring paths, a DB25 male splitter harness can help organize the connections in one assembly. This DB25 Male Splitter OBD Diagnostic Wiring Harness is designed for custom diagnostic wiring applications, including automotive testing and industrial equipment communication. The PA66+GF connector housing provides a practical option for projects where the connector structure and material are important selection points.
For customers developing a dedicated testing system, the DB25 male diagnostic wiring harness can be specified around the required connection layout. The number of branches, wire arrangement, and connector details should match the equipment design, so it's best to confirm these points with a wiring diagram before production. This helps make sure the finished harness suits the intended setup rather than relying on assumptions about the connector configuration.
Branch Layout, Cable Length, and Temperature Options
The standard cable length is 560±30mm, with customized lengths available for different equipment layouts. This gives buyers room to specify a suitable reach for their installation, whether the harness will be used inside a test instrument, connected to an automotive diagnostic system, or routed between industrial devices. The final length can be discussed alongside the branch arrangement and required connector positions.

The harness uses nickel-plated brass terminals and a PA66+GF connector housing. Its specified working temperature is -40°C to +105°C, with other temperature requirements available for discussion. The listed minimum insulation resistance is ≥10MΩ, and the maximum conduction resistance is ≤2Ω. The parameter sheet also states “DC 300V, 10MS Test”; please confirm the intended test method and voltage definition before publishing this as a formal electrical rating.
For Automotive Testing and Industrial Signal Connections
A multi-branch harness can be useful when test instruments and connected devices need a planned signal path within one wiring assembly. This product is intended for automotive diagnostic testing, industrial equipment communication, test instrument signal transmission, and electronic device wiring. Depending on the equipment interface, it may be considered as an OBD diagnostic cable adapter harness or a DB25 multi connector splitter harness, provided the final pinout and branch configuration match the application.
If your project needs an OBD diagnostic adapter for a particular test system, or a custom OBD diagnostic cable for signal routing, the actual wiring diagram is the best starting point. FBXSlink can also review requirements for a vehicle diagnostic cable adapter, car data adapter, or automotive diagnostic adapter when the requested interface and wiring arrangement are clearly specified. Please contact us to discuss the design and shipping cost.
Why Choose FBXSlink?
A multi-branch harness needs more than the right connector at the equipment end: the branch positions, wire lengths, and pin assignments all have to work together. FBXSlink develops automotive diagnostic cables and industrial wiring products, making these layout details an important part of reviewing a custom harness. For this type of project, a drawing or sample can help establish how the DB25 interface should connect with the rest of the test system.
Since beginning operations in Shenzhen in 2013, FBXSlink has built its work around wiring products for automotive and industrial applications. Our R&D and production teams can review customer-supplied specifications and discuss changes such as cable length, branch arrangement, or connector configuration. This is useful when a standard lead does not provide the connection layout required by a particular instrument or testing project.
