Drawing & BOM Review
Check connector and terminal compatibility, wire specifications, lengths, branches, labels, coverings and test requirements.
Wire Harness Engineering & Prototyping
Turn Your Wire Harness Requirements into Production-Ready Samples
Cablum supports drawing review, component confirmation, 2D wire harness drawings, wire samples, prototype assembly and testing. Cutting, stripping and terminal crimping are completed in our Shenzhen factory.
- 2D harness drawings available
- Wire samples available
- Typical prototypes in 7–10 days
- Initial engineering feedback in 3 business days
Practical Engineering Support
Clarify the design before prototype production
Our team reviews the information needed to build and inspect the harness. Use the wire harness drawing checklist and BOM requirements guide to prepare controlled inputs. We focus on manufacturability and production documents rather than claiming unsupported 3D-CAD or formal FAI services.
2D Harness Drawings
Prepare or refine 2D production drawings showing pinout, dimensions, materials and identification for customer confirmation.
Component Confirmation
Verify customer-specified part numbers and discuss available alternatives only when substitution is requested or necessary.
Response time: After the necessary technical information is received, initial engineering feedback is typically provided within 3 business days. Complex projects may require additional review.
Prototype Process Video
From Engineering Review to Production-Ready Prototype
See how drawings, BOM details and samples are converted into an agreed 2D harness definition, a controlled prototype build and project-specific validation.

AI-assisted technical visualization for educational purposes. Actual components, tooling, production steps and validation criteria depend on the approved drawing and project requirements.
Prototype Workflow
From requirements to customer validation
- 1
Review
Review drawings, samples, BOM, quantities and application requirements.
- 2
Confirm
Confirm wires, connectors, terminals, protection materials and test scope.
- 3
Document
Prepare the agreed 2D harness drawing and production information.
- 4
Build
Cut, strip, crimp and assemble prototype harnesses in our factory, including custom crimped wire assemblies where required by the approved project definition.
- 5
Inspect
Perform agreed visual, dimensional, electrical and mechanical checks.
- 6
Validate
Send samples for customer evaluation and record approved changes before pilot production.
Prototype & Material Samples
Evaluate materials and workmanship before production
Cablum can provide wire samples for customer evaluation and build small prototype quantities subject to component availability, tooling needs and project complexity.
The typical prototype lead time is 7–10 days after technical details and materials are confirmed. This is not a universal guarantee and does not automatically include new tooling.
What can be supplied?
- Wire samples for material confirmation
- Prototype wire harnesses and cable assemblies
- 2D harness drawings for approval
- Agreed inspection or test records
Quantity note: Single-piece and 1–10-piece prototype requests can be evaluated case by case; feasibility depends on components and setup requirements.
In-House Production & Checks
Core wire-processing steps completed in our factory
Automatic wire cutting, stripping and terminal crimping are performed at Cablum. Prototype inspection is defined by the agreed project scope.
Electrical
Continuity, pinout and other agreed electrical checks.
Mechanical
Pull-force, bending or dimensional checks where specified.
Visual
Workmanship, labels, routing, coverings and connector condition.
Documentation boundary: Cablum does not promise formal FAI reports, PPAP or IMDS on this service page. Available test records are agreed during quotation.
FAQ
Planning a harness prototype
Can Cablum create a drawing from my sketch or sample?
Cablum can review a sketch, sample, pinout or existing document and prepare a 2D wire harness drawing for confirmation. We do not present this service as general 3D-CAD modeling.
Can you provide wire samples before prototype production?
Yes. Wire samples can be supplied to help confirm construction, size, color or other relevant requirements before the harness build.
How long does wire harness prototyping take?
Typical prototype lead time is 7–10 days after technical details and materials are confirmed. Component availability, tooling and validation requirements may affect the schedule.
How quickly will I receive engineering feedback?
Initial engineering feedback is typically provided within 3 business days after the necessary technical information is received. Complex projects may take longer.
Are cutting, stripping and crimping performed in-house?
Yes. Wire cutting, stripping and terminal crimping are completed in Cablum's Shenzhen factory.
Do you accept single-piece or small prototype orders?
Small prototype quantities, including single-piece requests, can be evaluated case by case based on component availability, setup, tooling and project complexity.
Does every prototype include a formal FAI report?
No. Formal FAI reports are not promised. Applicable inspection and test records can be provided according to the scope agreed during quotation.
