Multi-branch and multi-connector assemblies

Custom Wire Harness Assemblies

Bring several connection ends, branch lengths and protection requirements into one assembly. LDZY builds to your drawing or helps prepare a drawing from your sample and connection requirements.

Typical production minimum: 500 assemblies. Samples generally free; project details are reviewed before production.

Two construction examples

Choose the layout around your connection points

Grouped colored wires with several connector housings and separate wire ends

Grouped wires with different connection ends

Identify each connector and loose-lead group separately. Crimped contacts, soldered ends and stripped/tinned leads can be specified. Use a branch schedule to match the endpoint, wire length and required end condition.

Sleeved bundle with separate connector branches

The example above shows how a covered bundle can separate into individually protected branches. Define the start and end of each protection zone, the exposed lead length and the space around each connector.

Protection and label arrangements follow your project requirements. Photographs illustrate construction styles; they do not establish a fixed pinout, rating or installation fit.

Separate routing from circuit connections

A branch schedule makes the drawing easier to review

Routing concept only, not a production drawing or pinout. Define the measurement surfaces, tolerances and electrical map on your project drawing.

Use one identifier for each endpoint

Keep the same endpoint references on the layout, connector drawings and electrical connection table. For example, a branch marked B should have its own connector reference, length datum and protection instructions.

Show the assembled routing rather than relying on a coiled product photograph. If branch locations are not yet fixed, mark them for review before sampling.

See drawing reference and contact-view guidance →
Connection ends
Give every connector or lead group an identifier. Include the selected housing and contact references, contact-view direction and unused positions.
Branch geometry
Mark where each branch leaves the main bundle. State the length datum and tolerance for each branch, not only the overall length.
Electrical connections
Provide an end-to-end connection table. Identify any shared connection explicitly; a physical branch on a sketch does not establish an electrical junction.
Protection and labels
Specify where each sleeve or protective covering begins and ends. Identify label locations, label content and any areas that must remain accessible.
Installation conditions
Include routing space, fixing points, movement and environmental requirements. Identify details still awaiting confirmation.

From the first reference to sample approval

Agree the complete harness before production

  1. Share what you have

    Send your drawing, BOM, sample details or routing sketch, together with sample and production quantities. Note which dimensions and connection details remain open.

  2. Confirm the drawing

    Review branch locations, length references, connection ends, protection and labels as one controlled revision. A physical sample is documented before a new sample is made.

  3. Review the sample in use

    Check the branch reach, connector access, routing and label visibility in your installation. Confirm the drawing and sample before placing the production order.

Electrical tests and production inspections

Every completed assembly is electrically tested for continuity, short circuits and wiring errors. Appearance and terminal retention are checked through periodic production inspections. Customer equipment and application validation remain separate from factory electrical inspection.

Questions before starting a harness project

Which end treatments and branch connections can you provide?

We can provide crimped contacts and connector housings, soldered ends, stripped and tinned leads, and multi-wire junctions. Specify the required construction and connection map; the connection method and dimensions are confirmed for the project.

How is this different from a discrete-wire assembly?

The constructions can overlap. Our discrete-wire page focuses on individual wires, contacts and end treatments. This page focuses on coordinating several branches, connection ends, protection zones and installation dimensions in one harness.

Can I start with a sample or a sketch?

Yes. With an existing drawing, we sample to the drawing. With a physical sample, we prepare a drawing before sampling. If neither is available, we can assist with drawing preparation from your requirements. Identify uncertain details so they can be reviewed.

Does a branch mean that the wires are joined electrically?

No. A branch describes how wires are routed. The connection table must separately identify every circuit and any required shared connection. The connection method and construction are reviewed for the project.

What are the sample and production conditions?

Samples are generally free, and we do not charge crimp-tooling or fixture fees. The typical minimum production order is 500 assemblies. Include your sample and production quantities for review.
