Multi Connector Split Custom Automotive Wire Harness 1868mm

Shenzhen Fubang Wiring Harness Co., Ltd. specializes in customized wiring assembly solutions for vehicle electronic systems, diagnostic equipment and automotive refitting projects. Equipped with automated cutting, crimping, soldering and full electrical testing production lines, we strictly implement IATF16949 manufacturing standards to guarantee stable performance for every finished assembly. As an experienced supplier of custom automotive wire harness, we can flexibly adjust connector collocation, wire gauge, braiding protection and pin assignment according to clients’ unique circuit layout requirements. All raw materials we select pass RoHS compliance inspection, enabling us to produce reliable automotive wiring harness that can resist extreme temperature, friction and chemical corrosion inside vehicle cabins and engine bays. We support sample verification, small-batch trial production and mass delivery to serve automotive electronics manufacturers, professional repair equipment brands and vehicle modification factories globally.

This multi-branch multi-connector assembly is a complex split-type wire assembly tailored for multi-module vehicle signal and power transmission, designed with one main 24Pin male plug branching out to 4Pin male, 3Pin female and dual 4Pin female connectors respectively. Different from simple two-way extension cables, this long-length assembly reaches a total overall length of 1868mm, with segmented reserved wire lengths and color-coded 20AWG signal wires for clear circuit identification. The whole main cable is wrapped with tight nylon braided sleeve, which greatly upgrades wear resistance, anti-interference ability and tensile strength compared with ordinary single-layer PVC wire, effectively avoiding circuit short-circuit caused by long-term vibration and friction during vehicle operation.

Each connection node of this harness strictly follows standardized production specifications of custom wiring harness. All wire stripping, tin soldering and heat shrink wrapping processes are operated with unified dimensional tolerances; multiple adhesive labels are attached on designated braided sections to facilitate assembly inspection and after-sales maintenance for equipment manufacturers. After full assembly, every piece undergoes DC 300V withstand voltage test, continuity test, insulation resistance test and tensile test between wire and terminals to eliminate hidden troubles like open circuit, misconnection and poor contact. The matched original automotive-grade connectors feature locking buckles to ensure tight plug-in without loose contact during bumpy driving or frequent disassembly.

Designed for complex multi-circuit vehicle electronic connection demands, this split wiring assembly is widely applied to whole-vehicle ECU interconnection, automotive diagnostic bench testing, refitting multi-functional on-board equipment and commercial vehicle multi-sensor signal convergence. Our engineering team provides flexible modification based on this standard model, including adjusting total length, replacing connector types, changing braiding coverage area or rearranging pin definitions. Drawing on our rich manufacturing experience of custom automotive wire harness, we deliver one-stop design and production services for clients who need non-standard multi-branch assemblies. Beyond mainstream passenger and commercial vehicle electronic systems, this automotive wiring harness can also be refitted for engineering machinery control equipment and special vehicle low-voltage circuit connection, bringing orderly, stable multi-channel signal transmission for diverse vehicle electronic projects.
