Custom Complex
Multi-Branch Wire Harnesses
Cablum designs and manufactures complex multi-branch wire harnesses that combine power, signal, data and control circuits into structured, installation-ready assemblies for automotive, industrial automation and advanced electronic equipment.
Managing Complexity Through Structured Manufacturing
Complex equipment often requires one harness to connect dozens of modules, sensors, power devices and control points. Accurate branch lengths, connector placement, circuit identification and electrical verification are essential for reliable installation and operation.
Controlled Branch Routing
Branch lengths, breakout points and connector locations are built according to approved drawings and tolerances.
Mixed Technologies
Power wires, shielded pairs, data cables and control circuits can be integrated into one assembly.
Identification & Labeling
Labels, wire IDs, connector coding and branch identification help support faster and more accurate installation.
Electrical Verification
Finished harnesses undergo point-to-point continuity, short-circuit and miswire checks.

Connector Coding
Connector labels, colors, keying and identification can support faster installation.
Mounting Hardware
Clips, grommets, brackets, cable ties and mounting points can be integrated where specified.
Serviceability
Branch identification and routing can be optimized to support installation, maintenance and replacement.
Repeatable Routing For Complex Harness Geometry
A full-scale assembly board provides a controlled physical layout for branch routing, breakout locations, connector orientation and mounting hardware placement.
Full-Scale Layout
The board reproduces the approved harness geometry to support repeatable branch lengths and breakout positions.
Connector Orientation
Connector direction, branch exit angle and mounting features can be controlled during assembly.
Dimensional Verification
Finished branch dimensions can be checked against drawing tolerances before shipment.
