Custom Molex Cable Assemblies
Source custom Molex cable assemblies for equipment builds, sample approval and repeat orders. Zeakka coordinates component sourcing and assembly review for your specified interfaces, cable layout and BOM.
Discrete-wire harnesses, jacketed cables and overmolded leads with project-specific connectors and wiring.
Single-ended, double-ended, extension, mixed-connector and branched cable assemblies built to the agreed wiring specification.
Specify each end of a Molex cable assembly
Define the complete connection between equipment interfaces. A Micro-Fit or Mini-Fit family reference helps select a starting point; the exact mating parts and circuit map define the assembly.
Identify both mating interfaces
Specify the housing, contacts and mating part at each end. Mixed-end assemblies also need the opposite connector, terminal or prepared-wire requirement.
Define the cable layout
Separate a two-ended cable from an extension or branched harness. Specify destinations and circuit assignments, including unused cavities, before comparing supplier proposals.
Review wire and protection together
A jacketed cable, discrete wires, sleeving and an overmolded termination have different review inputs. Check the selected wire and exit geometry against both connector interfaces.
If an off-the-shelf assembly already meets the approved interfaces, pinout, wire and length, it may suit the project. A custom request is useful when those details need to change. Use the off-the-shelf vs custom cable assembly guide to compare the requirements.
Agree the component sourcing route
Original Molex connectors can be sourced for use within finished cable assemblies, subject to the exact references and availability. They are not supplied as standalone original connector sales. Unbranded compatible candidates follow a separate drawing and mating-interface review; a shared pitch does not establish interchangeability. See the Molex alternative review guide.
A delivered project in detail
Delivered project
Four-position Micro-Fit-style cable
This delivered project used black four-position housings at both ends, red, black, yellow and white conductors, and a black outer jacket. The photographs show the overall construction and both terminations.
- Drawing preparation
- Zeakka prepared the project drawing for the four-position assembly, covering the connector references, cable construction and nominal dimensions.
- Sampling and testing
- Zeakka handled sample development and testing before bulk production. The public drawing summary uses the wire colours visible in the delivered-product photographs.
- Bulk production and delivery
- Zeakka coordinated bulk production through completed delivery. A similar project starts with the mating references, required circuit map and installation dimensions.

Connection arrangement at both ends
Both ends use the same arrangement, confirmed for this project. View each connector from the wire-entry side with its latch at the top.
| Wire | End A position | End B position |
|---|---|---|
| Yellow | Upper left | Upper left |
| Black | Upper right | Upper right |
| White | Lower left | Lower left |
| Red | Lower right | Lower right |
Positions above describe the wire-entry view, not manufacturer cavity numbers. A mating-face view reverses left and right. Wire colours do not assign voltage or polarity; this project connection map is not a universal Micro-Fit pinout.
BOM excerpt
Component references and cable construction from the supplied project drawing, with wire colours updated to the photographs. A reference followed by “or compatible” does not establish original-brand parts. This excerpt is not a certification or an inspection report.

- Qty 1
- 2. Housings, ends A and B
- 43025-0408 reference or compatible; 4 positions at each end
- Qty 2
What to send for a Molex cable assembly quote
Attach the information you already have and identify open questions. A complete drawing is helpful, but you can begin with a BOM, sample details or photographs.
- Interfaces and component choice
- Molex housing/contact references, mating parts and any different connector at the other end. State original-component requirements or permission to evaluate alternatives.
- Circuit map
- Cavity-to-cavity connections, numbering and viewing direction, polarity and any unpopulated positions.
- Wire and installation
- Wire specification and gauge, electrical duty, routing environment, and any jacket, sleeve or other protection requirements.
- Dimensions
- Finished length, measurement datums and tolerances; branch lengths and prepared-end dimensions where applicable.
- Quantity and schedule
- Sample, first-order and expected repeat quantities, packaging needs and target date.
- Approval and documents
- Drawing/BOM revision, sample acceptance points, required inspections and project-specific compliance documents.
From project review to production approval
Zeakka is a trading and sourcing partner. We coordinate supplier selection, quotation, sample review and production follow-up around the agreed specification.
1. Review feasibility and quote scope
Resolve missing specifications, compare suitable supplier options and identify proposed deviations. Confirm the component route, quantity, price and timing in the quotation.
2. Approve the sample and revision
Agree the drawing and BOM revision. Review the sample against the mating interface, circuit map, dimensions and equipment installation; record changes before production approval.
3. Confirm production checks
Each cable assembly receives continuity and short-circuit testing. Pull-force testing is sampled and project-specific. Agree any additional inspection, documentation and packaging requirements for the order.
Molex cable assembly FAQ
Can I start without a complete Molex cable drawing?
Yes. Send the available BOM, mating-part references, sample details or clear photographs, and mark what is unknown. These support identification and feasibility review; the build specification still needs to be agreed before production.
Can I discuss samples before a repeat order?
Yes. Provide the sample quantity, intended first order and expected repeat requirement separately. Sample arrangements and production quantities are reviewed for the specific configuration; an expected repeat order is not a confirmed minimum order.
When are MOQ, price and lead time confirmed?
They are confirmed in the quotation after the configuration, component availability, quantities and approval requirements have been reviewed. Include your target date so any sourcing or sample constraints can be identified.
Request a project quote
Send your drawing, BOM, reference, quantity and application so we can clarify the requirement before quoting.
