Wire Harness Manufacturing Built Around Your Connection Map
BespokeCable manufactures custom wire harnesses for industrial equipment, electronics, automation, and other OEM assemblies. A useful harness specification begins with the mating connectors and the circuit map, then defines wire, branch geometry, protection, identification, fastening, and test requirements. Pitch labels and connector-family names help narrow the choice, but they do not replace exact housing, terminal, and mating part numbers.
The live configurations below cover compact 0.8 mm through larger-pitch connection families, including labels associated with Hirose, JST, Molex, and SATA interfaces. These names describe the current product images and sourcing direction; they do not imply authorization by a component brand or universal compatibility across a family. Every quote should confirm the exact component, number of positions, wire range, keying, and approved alternative policy.
Send a drawing, net list, bill of materials, equipment layout, existing harness, or clear photos. We can review branch lengths, breakout locations, connector orientation, color sequence, labels, sleeve or conduit, shield termination, and order-specific inspection. A controlled first article and revision record provide the basis for repeat production.

Wire Harness Connector and Pitch Configurations
This live configuration is labeled as a 0.8 mm-pitch Hirose DF52 harness. Confirm the exact housing and terminal part numbers, position count, wire size, mating component, pin map, exit direction, and pull or retention requirement. The pitch label and photograph alone are not an approved specification.
This current card identifies a 1.0 mm-pitch Hirose DF19 harness. Supply the exact series and mating part, positions, conductor construction, shielding if applicable, finished length, and routing space. Review termination tooling and acceptance criteria against the nominated components before releasing production.
This 1.2 mm-pitch Molex-labeled configuration represents a compact wire-to-board harness. Confirm the exact Molex series and part numbers because pitch by itself does not establish mating compatibility. State circuit count, current, wire size, keying, latch, pin assignment, length, and expected handling.
This card is labeled 1.25 mm-pitch HRS DF13. Define the exact housing, contacts, mating connector, position count, and cable exit. Small-pitch assemblies are sensitive to wire selection, strip length, crimp setup, and handling, so include the electrical load and validation requirements in the RFQ.
This 1.5 mm-pitch JST ZH-labeled harness is for compact connections where the approved series and mating geometry matter. Confirm manufacturer part numbers, positions, wire, pin map, length, orientation, and any latching or strain-management requirements rather than ordering from the pitch name alone.
Specify this live 2.0 mm-pitch JST PH-labeled configuration with exact housing, contact, and mating parts. Provide position count, wire size, current, polarity, color sequence, finished length, and installation movement. Add labels or keyed variants to the controlled drawing when similar assemblies share equipment.
This 2.5 mm-pitch JST XH-labeled assembly is a representative harness, not a universal XH configuration. Confirm the exact series, circuit count, mating header, wire, pin map, exit, and retention. Where board space is constrained, include a drawing of the connector orientation and nearby components.
This 2.54 mm-pitch Hirose HIF3B-labeled configuration may suit a multi-position board connection. Specify the exact connector part numbers, position count, cable construction, contact assignment, strain relief, polarization, and routing. Any ribbon or discrete-wire choice should follow the signal and installation requirements.
Review this 3.0 mm-pitch Molex Micro-Fit-labeled harness as a complete mating system. State the housing, terminal, positions, row arrangement, wire size, current, circuit map, latch access, and length. Do not infer rating or compatibility from the family name without the exact component data.
This 3.5 mm-pitch Molex Ultra-Fit-labeled configuration is retained from the live product range. Confirm the exact series and part numbers, contact count, keying, conductor, electrical load, temperature, and mating-cycle needs. Provide the equipment layout when connector access or bend clearance is limited.
This 3.8 mm-pitch SATA connector harness label represents a power- or equipment-specific assembly that must be defined by connector type and pin use. Confirm the mating interface, contact count, voltage rails, wire sizes, pin map, branch arrangement, and retention. Do not assume a standard storage pinout for a custom build.
Please quote this 3.96 mm-pitch JST VH-labeled harness based on the exact component and electrical requirements. Provide the housing and terminal parts, positions, wire size, current, pin assignment, length, and mating header. State whether vibration, service access, or repeated connection affects the retention requirement.
This 4.2 mm-pitch Molex Mini-Fit-labeled configuration is a representative multi-circuit harness. Confirm the row and position count, keying, housing and terminal part numbers, conductor sizes, circuit loads, and pin map. Branches, labels, and latch clearance should be shown on the drawing when the harness is installed in a dense enclosure.
This 5.7 mm-pitch Molex Mega-Fit-labeled assembly requires a defined mating system, wire, and load. State positions, conductor size, voltage and current per circuit, keying, length, routing, and retention. Thermal or derating decisions belong to the approved component and equipment design, not the card title.
This 5.08 mm-pitch Molex KK508-labeled configuration should match the exact housing, contact, and board header. Provide the position count, wire size, pin map, polarization, finished length, and expected installation handling. If more than one similar header exists, include part numbers and a marked photograph.
This 7.5 mm-pitch JST V-labeled harness remains a distinct live configuration. Confirm the exact connector and mating parts, circuit count, wire size, electrical load, pin assignment, length, and environmental conditions. Pitch and brand-family wording alone cannot establish the correct terminal or approved rating.
Control the Exact Connector System
Record the housing, terminal, seal, lock, and mating-part numbers for every endpoint. Similar pitch and appearance do not prove compatibility. If an approved equivalent is allowed, define the dimensions, material, contact range, keying, and evidence that it must match before a substitution is considered.
Turn the Schematic into a Production Pin Map
List each wire from the connector and pin to its destination, including color, size, signal name, shield or drain termination, and any splice. Mark unused positions and polarity. This table becomes the foundation for assembly instructions, electrical test programming, and fault investigation.
Dimension Branches from Agreed Datum Points
Show overall and branch lengths, breakout positions, connector orientation, exit direction, tolerances, and fastening points. Include the installed bend path and service movement. Clear datum points prevent different teams from measuring the same harness in incompatible ways.
Select Protection for the Real Environment
Use sleeve, braid, tape, conduit, heat shrink, grommets, or overmolding only where the routing and environment justify them. State abrasion, vibration, flexing, temperature, liquid, and EMI conditions. Protection should solve a defined risk without making the assembly too stiff or difficult to install.
Release Repeat Orders from an Approved First Article
Verify mating, wiring, dimensions, orientation, labels, workmanship, and the agreed electrical or mechanical tests on the sample. Freeze the drawing, bill of materials, process notes, and packaging after approval. The inspection plan should follow that controlled revision.
Yes, identification can begin with the mating equipment, a physical sample, dimensions, and clear photographs. The quotation should mark the connector as provisional until the exact production part, mating fit, contacts, and keying are confirmed.
Yes, when the circuit map and connector terminals support them. State the current, voltage, and function for each circuit, and identify the required wire. Review the terminal wire range, crimp setup, routing, and splice design for every conductor size.
They can when the drawing defines each dimension from an agreed datum and assigns a practical tolerance. Critical mating or clip locations may need tighter control than free-routing sections. Confirm how the buyer will measure the finished harness.
Evaluate these protections for abrasion, temperature, flexibility, diameter, and installation needs. Provide coverage limits, overlap, termination method, color, and any restricted materials. The selected protection should not obstruct connector latches or service points.
The schematic must define where each shield or drain connects, whether one or both ends are bonded, and the required hardware or splice. Do not infer shield termination from cable construction; it is part of the equipment grounding and EMC design.
Yes, provide the label text or data rule, material, size, position, barcode format, and durability requirements. A sample should confirm readability and placement before the artwork and application method are frozen.
Review a nominated component for availability, authenticity controls, lead time, packaging, and application tooling. State whether substitutes are prohibited or require written approval, and whether the buyer will supply any constrained parts.
Issue a revised PIN table and drawing, and identify affected test files, labels, and materials. A new or modified sample may be needed before production. Do not rely on an email instruction that is not incorporated into the controlled revision.
Plan kit packaging once you define the contents, quantities, labels, sequence, accessories, and verification method. Provide the kit bill of materials and barcode or traceability rules so that missing or mixed components can be detected.
Separate prototype quantity, pilot build, expected batch size, and annual forecast. These figures support component purchasing, tooling, test-fixture, and packaging decisions without creating an unverified universal MOQ or lead-time promise.
How to Prepare a Wire Harness RFQ
A wire harness is not fully defined by connector pitch, length, or a photograph. It is a controlled network of connections that must fit the equipment, carry each circuit, and remain identifiable through assembly and service. The strongest RFQ separates electrical, mechanical, material, and commercial requirements so open decisions are visible before sampling.
1. Create an Endpoint List
Name each connector, terminal, splice, ring lug, sensor, or open end. Include manufacturer and part number where available, mating part, gender, position count, keying, and required hardware. For legacy or unknown parts, provide samples and dimensioned photographs, but plan to document the selected production component after identification.
2. Provide a Pin-to-Pin Table
For every circuit, list connector reference, pin, destination, wire size, color, and function. Identify twisted pairs, shields, drain wires, and grounds. Mark jumpers, splices, and unused positions explicitly. When multiple voltage rails or signal types share a harness, show them separately so wire and routing choices can be reviewed.
3. Define Wire and Cable Construction
Specify conductor size, stranding, insulation, temperature or environmental requirements, and any controlled cable. If the construction is open, provide voltage, current, signal, flexing, and routing conditions instead of selecting solely by a familiar wire code. Component approvals and finished-harness compliance are different evidence scopes.
4. Dimension the Harness in Its Installed Shape
Use an assembly drawing with defined datum points. Show overall length, each branch, breakout angle, connector orientation, tolerances, tie or clip locations, and the space available for bending. A flat drawing may also need an installation view when the harness turns through several planes.
5. Specify Protection and Strain Management
Identify abrasion points, moving sections, hot surfaces, sharp edges, chemicals, and vibration. Select sleeve, conduit, tape, braid, heat shrink, grommets, clamps, or overmolding for those conditions. Strain relief should protect terminations without transferring excessive stiffness into a moving cable section.
6. Plan Identification and Assembly Error Prevention
Use wire colors, branch labels, connector IDs, keying, and fixtures to prevent cross-connection. Provide label content, barcode data, material, position, and durability needs. When two branches look alike, define a visual or mechanical distinction instead of relying only on operator memory.
7. Define Inspection and Testing
Continuity and pin-to-pin verification should follow the approved connection table. Add short-circuit, polarity, dimensional, visual, pull, insulation, dielectric, or functional checks only with agreed methods and criteria. Test coverage, sampling, and record retention should match the project risk and order requirements.
8. Approve Materials and Changes
Freeze the connector, terminal, wire, and protection materials after sample approval. Define which sources are mandatory and which characteristics an alternative must match. A terminal that fits the housing may still have a different wire range, plating, retention, or application tooling, so substitutions need review.
9. Prepare for Repeat Production
Assign an assembly part number and revision. Control the drawing, bill of materials, test file, label artwork, work instructions, and packaging together. If several length or connector variants exist, use a configuration matrix that makes valid combinations explicit.
