Complex Cable Assembly and Wire Harness Projects

Some cable assemblies and wire harnesses combine cable preparation, crimping, soldering, overmolding, harness layout, labeling, testing, and export packing. Planning these operations from one drawing package reduces handoff errors and makes sample and production builds easier to compare.

Project examples

Build detail examples

The examples show cable routes, connector ends, molded features, and other assembly details used to align drawings, samples, tests, and required records for quotation and build planning.

Wire harness routed on a layout board with branch paths and connector positions — Harness routing baselineRouting-board context shows how branch layout, connector position, and inspection points need one drawing baseline.

Cable insert molding setup with cable positioned in a fixture — Molding step in a combined buildMolding setup belongs in the same process plan as cutting, termination, routing, inspection, and packing.

Connectorized wire harness terminal ends with visible wire colors — Terminal‑end detailEnd-treatment detail helps align crimping, soldering, connector fit, labels, and electrical checks.

For assemblies that combine several manufacturing operations

The assembly includes crimping, soldering, shielding, overmolding, and routing features
Several connector types or branch lengths need to stay coordinated
You need one inquiry package for manufacturing, testing, and delivery details
The project may require both in-house process planning and component sourcing

Use one drawing, BOM, pinout, test criteria

Assembly drawing, wiring table, pinout, and branch dimensions
BOM, connector part numbers, wire or cable construction, and no-substitution notes
Quantity, sample plan, required tests, records, labels, packing, and delivery destination

Process planning

Termination, molding, routing, testing alignment

Process order for cutting, termination, molding, routing, packing, and shipment records
Crimp, solder, shield handling, overmold, and assembly constraints
Continuity, polarity, hi-pot, functional, or visual inspection requirements

Drawings and notes

Pinouts, molded geometry, routing, test evidence

Assembly drawing, wiring table, pinout, and sample photos
Photos of critical routing, exits, or mating equipment when available
Test method, pass/fail criteria, and required record format

Complex Wire Harness AssembliesComplex harnesses combine several branches, termination types, labels, and protective materials in one assembly. MTTJ cuts and prepares the wires, crimps or solders the specified terminals, lays out the harness, adds protection, and checks circuits and identification against the drawing.IP67-Sealed Communication Cable AssembliesThis product family combines IP67-sealed circular connector interfaces with molded cable exits and specified conductor or terminal ends. MTTJ prepares the cable and connector, terminates the wiring, molds the exit, and checks the finished route, pinout, and sealing requirements against the supplied build package.Custom Cable AssembliesMTTJ builds drawing-based cable assemblies for power, signal, data, and control connections. In-house work can include cutting, stripping, crimping, soldering, connector assembly, labeling, electrical checks, and packing.

Cost DriversCost is driven by the build definition: cable construction, connector choice, termination labor, overmolding, custom extrusion, testing, documentation, packaging, and quantity. A complete drawing package helps MTTJ price the real work instead of assumptions.Supplier EvaluationEvaluate a cable assembly supplier against one controlled build package, not a general capability list. The comparison should cover drawing and BOM fit, in-house and supplier-coordinated work, tooling, tests, records, packing, change control, and the cost inputs needed to deliver the assembly.Harness InputsA good harness input package shows the route, branches, connectors, terminals, labels, protection, wiring table, tests, and packing notes in one place. Missing branch or terminal data is what most often slows a harness RFQ.

FAQ

Multi-process cable assemblies

Can one assembly combine several manufacturing processes?

Yes. A single drawing package can cover cable preparation, termination, overmolding, harness layout, labeling, testing, and packing. The sequence and tooling are planned as one build.

What creates the most risk in complex assemblies?

Unclear pinout, branch length, connector selection, shielding, and test criteria can all change manufacturing steps, so they belong in the same inquiry package.
