Cable Assembly
A cable loom is a bundled wiring assembly that routes conductors, connectors, protective sleeves, labels, and branch exits as one install-ready unit. We build custom cable looms for OEM buyers who need routing control, repeatable termination quality, field-service labels, and documented testing before production release.
Application Context
A loom fails commercially when it fits the drawing but not the equipment. We review the installation path, branch stress, protection stack, and inspection plan before quote.
Cable Loom Scope
A loom fails commercially when it fits the drawing but not the equipment. We review the installation path, branch stress, protection stack, and inspection plan before quote.
A wire loom is a routed wire bundle with branch exits, connector orientation, protection, and labels arranged for fast equipment installation. We build against fixture-board dimensions so branch length, breakout location, and connector clocking remain repeatable from sample to production.
A protective cable loom is a harness assembly that uses conduit, braid, tape, sleeve, heat shrink, or grommets to reduce abrasion, splash, vibration, and service damage. We flag rub points and bend-radius concerns before the first sample is built.
Cable loom quality depends on termination control as much as routing. We align wire gauge, terminal family, applicator tooling, strip length, crimp height, pull checks, and connector insertion inspection with the released BOM.
A custom cable loom should not rely on tribal assembly knowledge. We define build photos, route boards, label maps, test records, revision control, and packaging notes so repeat orders match the approved sample.
Engineering Challenges
Branch datums, sleeve stop points and connector clocking are defined before sampling, and branch geometry is fixed on the fixture board so the loom installs cleanly and repeats from sample to production.
Abrasion, splash, oil exposure, outdoor UV, bend radius, vibration, temperature and service access are reviewed to choose conduit, braid, tape wrap, heat shrink, boots or grommets by zone.
Wire gauge, terminal family, applicator tooling, strip length, crimp height, pull checks and connector insertion inspection are aligned with the released BOM.
Connector availability, sleeve choice, tooling, sample quantity and annual volume are separated as lead-time drivers, with buyer-approved alternates proposed where form, fit and interface allow.

Manufacturing Process
Quality & Testing
Every cable loom gets 100% continuity and polarity testing, with hipot or insulation resistance when specified. Release documentation includes DFM feedback, sample records, test reports, a label map, packaging notes, and revision control.
Why WHP
The lowest piece price does not help if the loom causes installation delays, connector strain, or field wiring mistakes. We quote the assembly around how it will be built, tested, packed, and installed.
Our engineers check branch exits, connector orientation, protection zones, label readability, and service access before quote. In loom RFQs, we often find missing branch datums, undefined sleeve stop points, or connector clocking gaps before a buyer has paid for samples.
Many buyers begin with an old loom sample, a wire list, or equipment photos. We help convert that package into controlled build notes, test scope, and quote assumptions so the second order does not drift from the approved first article.
IPC-A-620 is used for workmanship expectations, UL-758 is reviewed for wire style and insulation requirements when specified, and ISO 9001 release controls support repeat production. For automotive programs, IATF 16949-style discipline can be aligned with customer PPAP or sample approval needs.
Instead of a vague quote, we separate the risks that affect timing: connector availability, sleeve choice, tooling, sample quantity, annual volume, test fixture needs, labels, and packaging. That lets buyers compare suppliers on the real constraints.
IPC-A-620 for workmanship, UL-758 for wire style and insulation when specified, and ISO 9001 release control for repeat production — with IATF 16949 discipline available by automotive program.
FAQ
OEM Program Entry
Send your drawing, wire list, sample photos, connector references, sleeve requirements, target quantity, and test needs. We will review the loom route, protection stack, termination risk, sample timing, and production release plan.

Applications
Cable loom sourcing is most valuable when equipment teams need consistent installation, cleaner service work, and fewer wiring errors across repeat builds.
Automotive, electric vehicle, motorcycle, truck, trailer, and off-highway equipment looms with branch protection, clips, conduit, and labels planned around the installation path.
Panel-to-sensor, motor, actuator, and control harness looms for automation equipment where routing, shield separation, and clear labels reduce assembly time.
Replacement or retrofit loom assemblies with connector maps, color coding, labels, and packaging intended for technicians who need fast and low-error installation.
Mixed-gauge loom assemblies with power, signal, sensor, and communication branches separated by shielding, sleeve choice, or routing rules when the equipment requires it.
RFQ
Representative project type (illustrative)
Representative project type we handle, shown for illustration. Not a specific named customer.
Scenario. An industrial buyer brings a Cable Loom program where a connector or component on the original bill of materials carries a long lead time or limited availability.
Challenge. A specified part can dominate the schedule when its lead time or minimum order quantity does not match the program timeline, putting the whole release at risk.
Solution. We flag the constrained part during RFQ review and, where the form, fit, and mating interface allow it, propose a buyer-approved alternate with transparent cost and MOQ notes — the buyer keeps the final decision.
Result. With the sourcing risk surfaced early and an approved alternate path available, the program stays on its intended schedule instead of stalling on a single part.
