Complex Multi-Branch Wire Harness Manufacturing
Cablum manufactures custom multi-branch harness assemblies for complex, low-volume OEM projects that need several branches and connection points built to a customer-approved electrical and physical layout. The approved requirements define branch geometry, breakout locations, connections, identification and inspection.
Engineering Definition
Complexity comes from coordinating the electrical connection map with the harness’s physical layout. Branch points, breakout locations, connection destinations, installation constraints, identification and inspection criteria must describe the same finished assembly—not simply a harness with many branches.
Each branch point changes the relationship between the main bundle and its outgoing paths. Breakout locations, branch sequence and the destination of each path should be defined so the connection map and physical layout describe the same harness.
Branch dimensions, breakout positions and the relationship between connection points establish the required harness geometry. The definition should also reflect the available installation space and layout constraints supplied for the project.
Different connection destinations must remain distinguishable in the project documentation. Branch references, connection-point identification and any required labels or identifiers should be defined within the customer-approved requirements.
Inspection criteria should identify the documented dimensions, identification features and acceptance conditions that apply to the finished custom wire harness. The required testing scope is defined at project level alongside those criteria.
RFQ & Engineering Review
For a quotation and engineering review, send the information currently available for branch geometry, connections, components, installation constraints, quantity, inspection and acceptance. Cablum can then identify any missing details that should be clarified before manufacturing.
Provide the available overall and branch dimensions, breakout positions and any dimensional criteria already defined for the project.
Reference each connection point and branch to its intended destination so the electrical connections and physical layout can be reviewed together.
Include the component specifications currently available for the project, together with the connection information associated with those components.
Describe the available installation space, routing constraints and the required relationship between branches, connection points and equipment locations.
Identify the dimensional, identification and documentation requirements that should be included in the approved inspection scope.
Define the available criteria used to determine whether the finished harness meets the approved project requirements, including the required testing scope where applicable.
Together, these inputs give engineering and sourcing teams a clearer basis for reviewing project scope and preparing a quotation.

1:1 Drawing Support
Cablum can provide 1:1 drawings for applicable complex multi-branch harness projects. A full-scale drawing gives the project team a clear reference for reviewing the required harness geometry before manufacturing.
The drawing scope is determined by the project and the information available for review.

Quality & Inspection
Inspection for complex multi-branch harnesses can include documented dimensions, identification, visual criteria, continuity or pinout verification when specified. The final inspection and testing scope follows the approved project requirements.
Specific test methods are included only when they are defined and approved for the project.
