e design and manufacture customized car wiring harness tailored to specific vehicle electronic layouts, and our production lines cover a wide range of custom wiring harness for sensor interconnection, control module wiring and industrial signal transmission. To complement vehicle service tooling, we also supply compatible OBD diagnostic adapter and extension cables that work with mainstream diagnostic platforms. All products follow RoHS material requirements and undergo full electrical inspection before shipment.
This HDB26 to 5 way urea level sensor harness is built as an integrated interconnection solution for multi-sensor urea tank systems. Rather than using several separate jumper wires, this assembly consolidates five urea sensor signal circuits into one HDB26 main interface, which greatly simplifies vehicle wiring layout and reduces the risk of loose connections caused by scattered cables. The five branch ends cover both flat and square 4Pin urea sensor connector styles, offering broad compatibility with Cummins and other common urea level sensor configurations used in heavy-duty trucks. A built-in PCB board organizes the pin mapping inside the main connector, keeping signal paths neat and stable even under long-term vehicle vibration.

Each branch uses UL2464 22AWG 4-core shielded cable with aluminum foil shielding, which helps maintain clean sensor signals in the electrically noisy environment near the engine and chassis. The black PVC jacket resists oil, moisture and mild abrasion typical of commercial vehicle underbody installation. Branch cables are individually marked with clear labels, allowing technicians to identify each sensor circuit quickly during assembly and after-sales service. The HDB26 male connector uses machined pins for consistent contact reliability, and the overmolded strain relief at each connector exit distributes bending stress to protect internal conductors from fatigue failure.
Finished assemblies pass 100% continuity testing, DC 300V withstand voltage verification, insulation resistance and conduction resistance checks. Insulation resistance is kept above 10MΩ and conduction resistance is limited to 2Ω maximum, ensuring dependable signal quality for urea level reading and SCR system control. Every connector housing is visually inspected for cracks, deformation and surface defects, and all materials meet RoHS compliance. The harness is individually bagged and packed flat with layer separation to avoid damage during transit and storage.
This harness is commonly used in heavy-duty truck SCR urea systems, multi-sensor urea tank installations, Cummins aftertreatment control units, diesel emission management modules and commercial vehicle sensor integration projects. It provides a clean, factory-style wiring solution for both original equipment assembly and aftermarket retrofit work. If your project requires different branch counts, connector styles, cable lengths or custom pin mapping, we can adjust the design to create a dedicated custom wiring harness for your application. We continue to refine the durability and signal integrity of every customized car wiring harness we produce, and our OBD diagnostic adapter range can be paired with these harnesses to support complete vehicle diagnostic and service workflows.
