We excel at developing customized car wiring harness according to customer drawings, pin definitions and application scenarios. Our engineering team provides one-stop support covering schematic review, sample validation, FAI testing and mass production. We design and manufacture diverse automotive wiring harness for vehicle diagnosis, on-board electronic communication and engine signal transmission, fully meeting the strict durability standards of commercial vehicle aftermarkets.
This Cummins 9Pin Y-splitter cable is a dedicated branch wiring assembly designed for Cummins engine diagnostic work. Different from straight-through connection cables, this harness adopts a Y-type split structure: one green 9Pin male connector branches into two independent 9Pin female connectors, enabling simultaneous signal reading and data collection during engine inspection. Strictly following drawing specifications, the cable applies controlled wire twisting with fixed twist pitch to reduce signal crosstalk. Premium braided mesh sleeves are wrapped outside wires to resist abrasion, effectively extending service life in complex workshop maintenance environments.

All raw materials comply with RoHS environmental standards. The connector housing adopts high-strength PA66+GF automotive-grade material, featuring stable sealing performance and strong resistance to vibration and temperature fluctuation. Nickel-plated brass terminals maintain stable conductivity and excellent anti-oxidation capacity under long-term repeated plugging. Every finished harness undergoes full electrical testing before delivery, including continuity check, DC 500V withstand voltage test, insulation resistance and conduction resistance inspection to eliminate open circuits, short circuits and miswiring risks. Clear printed labels are attached to each cable for convenient identification, sorting and equipment management during daily maintenance work.
This Y-type splitter wiring assembly is widely used in heavy-duty truck maintenance, diesel engine ECU calibration, commercial vehicle fault diagnosis and on-site vehicle inspection projects. It can cooperate with mainstream diagnostic tools to realize multi-channel signal acquisition, greatly improving the efficiency of engine data detection and troubleshooting. Whether you need standard splitter cables or modified customized car wiring harness for special engine diagnostic equipment, we can adjust wire gauge, total length and connector layout as required. We keep optimizing the performance of every automotive wiring harness to adapt to harsh working conditions such as temperature variation and mechanical friction in commercial vehicle maintenance scenarios. Apart from engine diagnostic branch cables, we also develop various signal transmission assemblies for off-highway machinery, construction machinery and agricultural vehicles. If you have wiring development demands, welcome to send technical specifications for sample support and competitive quotation.
