Wire harnesses & cable assemblies
BGS is a wire harness supplier in India, coordinating custom harnesses and cable assemblies through manufacturing partners for OEMs and overseas buyers.
Send your drawing, BOM, pinout and quantities. We coordinate source review, quotations, samples and agreed inspection.
Start with a drawing, wiring diagram or reference sample. We’ll clarify what is missing.
Choose the assembly architecture
A wire harness organises wires and terminations around the circuits and physical layout of your equipment. Define the required architecture before comparing manufacturing sources.
Multiple circuits. Controlled branches.
For equipment with several connection points, breakout positions and installation constraints. Review wire sizes, branch lengths, connector references and protection as one complete assembly.
Use a branch drawing, circuit table and connector BOM.
Define breakouts, routing and identification.
Specify the cable, both interfaces, pin-out and overall length.
Confirm connector, contact and seal references.
List each wire, cut length, terminal, label and quantity.
Agree test coverage and packaging.
The images illustrate assembly types. Product details and manufacturing feasibility are confirmed against your approved specification.
Evidence for your source review
Match the evidence to the proposed manufacturer, product and market. Include your requirements in the RFQ so the relevant records can be requested and checked during source evaluation.
Identify the certificate holder and actual manufacturing facility. Review the standard, certified scope, issuing body and validity for the proposed source.
Applies to the named manufacturer or facility.
Where applicable, identify the covered product/model, configuration, market and approval or file reference. Confirm that the proposed item falls within the documented scope.
Applies to the identified product and approval scope.
Component approvals do not automatically establish finished-harness approval. Define the assembly requirements, workmanship criteria and required test records.
A clear brief makes offers comparable
Send the information available. BGS will identify what needs clarification before a manufacturer can assess the requirement.

Machinery and automation, appliances and HVAC, control panels, instruments and other OEM equipment. Share the operating conditions and any industry-specific requirements; suitability is evaluated for the selected source.
Control the interfaces
Define what each branch connects, how it is routed and how it is identified. Connector, terminal and protection references must stay aligned with the approved drawing and BOM.
Specify mating references, contact size, seals, locking features and wire range. Crimp tooling and acceptance criteria should match the selected contact system. Proposed alternatives need buyer approval.
Define breakout positions, installation clearances, clips, grommets and restraint points. Sleeving, conduit and heat shrink are evaluated against the actual mechanical and environmental requirements.
Agree wire IDs, connector labels, customer part number, drawing revision and traceability records. Define how component, material or process changes will be submitted for approval.
Drawing revision, approved components, dimensions and acceptance criteria establish the quotation basis.
Alternative components, materials or processes are reviewed with you before approval. Unresolved assumptions remain visible.
Define what acceptance means
Testing is configuration-specific. Agree methods, limits, sampling or unit coverage and the records needed for your harness programme.
Defined point-to-point continuity, circuit mapping and checks for unintended connections against the agreed test specification.
Crimp workmanship, contact retention and any pull-force or crimp measurements required by the specified process.
Branch lengths, connector orientation, breakout positions, protection and installation geometry.
Insulation resistance, dielectric withstand or other tests only where applicable and defined for the assembly.
If IPC/WHMA-A-620 or another customer standard is required, identify the applicable revision, class and additional requirements. Manufacturer capability and any required credentials must be verified for the selected source.
Every unit on a BGS purchase order is inspected against agreed criteria. For manufacturer-direct orders, BGS inspection scope, responsibilities and service terms are agreed separately.
One coordination route
Drawing, BOM and installation requirements.
Manufacturing fit, component availability and quotation assumptions.
Samples, documentation and defined inspection or test criteria.
Agreed production follow-up, inspection, packing and dispatch planning.
Before you send the drawing
BGS is a supplier and sourcing partner. Manufacturing is carried out by selected Indian manufacturing partners. Your quotation defines the proposed source, supply responsibilities, sample approval and agreed inspection or testing scope.
Yes. Share photographs, the application, connector references and quantities. A sample can support the review, but the required pin mapping, dimensions, materials and acceptance criteria still need to be defined before production.
Yes. Include the manufacturer and exact references in the BOM. Availability and assembly feasibility are reviewed for the selected source. Any proposed substitution must be submitted for your approval rather than assumed equivalent.
Yes. Include the installation environment, destination markets and applicable customer or product requirements. Wire, connector, material and documentation needs are evaluated for the specific equipment; the destination and application determine the requirement.
The configuration, component availability, tooling and test-fixture needs affect sample cost, order quantities and timing. BGS coordinates clarification with the manufacturing source and records the agreed basis in the quotation.
No. Continuity checks the defined electrical paths. Pin mapping, insulation, mechanical fit, crimp workmanship and any additional electrical tests require their own agreed methods, limits and records.
Start with the connection problem
Send a drawing, wiring diagram or reference sample details. We’ll review the brief and clarify the information needed to assess a manufacturing source.
Detailed drawings can be discussed under an agreed confidentiality arrangement where required.
