One plant, one drawing standard, eight product families. Everything is built to a drawing you approve, with the OEM connector series retained so the loom plugs in without adapters.
Every assembly in the vehicle built as one matched set: engine room, body, dashboard, chassis and rear body. Correct splice points, correct circuit count, one drawing pack.
Also ordered as: complete wire harness set, full wiring loom, body-in-white harness
Firewall-to-engine loom with injector, coil, O2, cam, crank, knock and MAP branches. Sealed ECU header, heat-rated sleeving, OEM connector keys retained.
Also ordered as: engine wire harness, ECU harness, engine loom, EFI harness
Main body loom, IP loom and cabin sub-looms including BCM, fuse/relay block, audio, immobilizer, airbag and HVAC control branches.
Also ordered as: body loom, main harness, interior harness, instrument panel harness
Wheel-speed, ABS/ESP, ride-height, fuel-tank and rear lamp runs in abrasion-resistant conduit with sealed sensor connectors and trailer socket.
Also ordered as: chassis loom, underbody harness, ABS harness, rear lamp harness
Shielded HV power looms, PDU harnesses and charging inlets for battery, inverter, OBC and motor runs. HVIL interlock loop, orange jacket, IP68 connectors, 3000 V AC hipot on every unit. Five in-house connector series from 32 A to 250 A — see the high-voltage page.
Also ordered as: HV cable assembly, EV battery harness, orange HV loom, PDU harness, charging inlet harness
Body-builder, motorhome, ambulance, refrigerated and chassis-cab looms with a dedicated fuse block so nothing is tapped into the OEM BCM. Drawing supplied with every build.
Also ordered as: upfitter harness, body builder loom, auxiliary harness
Section looms and pigtails for the failure points that do not justify a full loom: hinge loops, injector sub-looms, door grommet sections, connector pigtails with seals and terminals.
Also ordered as: harness repair kit, pigtail harness, section loom, connector pigtail
Matched components for workshops that build their own looms: TXL/GXL wire, unsealed and sealed terminals, connector housings, seals, cavity plugs and corrugated conduit.
Also ordered as: harness components, terminals and seals, wire and connector kit
Buyers order the same product under different words depending on where they are. If your list says one of these, send it as it is — we quote on the part, not the wording.
| Wire harness / wiring harness | The standard term in North America and in OEM documentation. A complete assembly of wires, terminals, connectors, splices and protective coverings, built for a defined routing in the vehicle. |
|---|---|
| Wiring loom / cable loom | The standard term in the UK, Ireland, Europe, Australia and much of the Middle East and Africa. Some workshops use “loom” for the bundled and sleeved wires and “harness” for the terminated assembly, but in ordering practice the two are interchangeable. |
| Harness assembly / cable assembly | “Assembly” is what the drawing and the purchase order call it — for example “engine harness assembly, part no. 82121-0K010”. A cable assembly usually means a single cable run with connectors at both ends rather than a branched vehicle harness. |
| Pigtail | A short lead with the connector already terminated, spliced onto an existing circuit instead of replacing the whole loom. |
| Section loom / sub-loom | One branch of a larger harness — a door loom, a hinge loop, an injector sub-loom — sold as its own part number. |
These are the defaults. If your drawing specifies something different, we build to your drawing.
| Conductor | Stranded bare copper, 0.22–6 mm² (AWG 24–10); 8–35 mm² battery and HV cables on request |
|---|---|
| Insulation | TXL (irradiated PVC, 125 °C), GXL (glass braid), TPE where flexibility matters, silicone for high-temperature branches |
| Connectors | Sumitomo, Yazaki, Aptiv/Delphi, TE Connectivity, Molex, KET, JAE — original series or documented equivalent |
| Terminals | Open-barrel crimp with pull-test record; sealed terminals with individual wire seals on exposed joints |
| Protection | PVC and non-woven tape, corrugated and split conduit, heat-shrink breakouts, grommets, boot seals |
| Temperature range | -40 °C to +125 °C continuous; +150 °C on engine-bay branches |
| Electrical test | 100% continuity, short-circuit and pin-out test against the approved drawing; hipot 3000 V AC on HV assemblies |
| Mechanical test | Crimp pull test, terminal retention, 300,000-cycle bend on hinge loops, vibration and salt-spray on chassis looms |
| Traceability | Wire lot, terminal lot, operator and test result recorded per unit; test record shipped with the carton |
| Packing | Coiled and labeled per part number, returnable racks for volume, export carton with desiccant for sea freight |
Email a photo of the OEM label, a pin-out or the old loom itself. Our engineers will confirm fitment, circuit count and connector family, then send a quote and a sample date within 24 hours. Samples ship in 7–10 days; production takes 25–30 days.
