IATF 16949 certified harness plant · Hebi, China

Wiring harness products: full sets, single assemblies and service sections

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.

05

High-voltage & EV 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

  • 1000 V DC rated
  • 32–250 A connector series
  • HVIL loop
  • 3000 V AC hipot
06

Custom & upfitter loom

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

  • Own fuse block
  • Relay-switched
  • Separate earth bus
  • Drawing delivered
07

Repair sections & pigtails

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

  • From 1 m
  • Sealed splices
  • Color matched
  • Low MOQ
08

Wire, terminal & connector kits

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

  • TXL / GXL / TPE
  • Sumitomo / Yazaki / TE
  • Seals & plugs
  • Cut lengths to order

Naming

Harness, loom or assembly: the same part under three names

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 harnessThe 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 loomThe 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.
PigtailA short lead with the connector already terminated, spliced onto an existing circuit instead of replacing the whole loom.
Section loom / sub-loomOne branch of a larger harness — a door loom, a hinge loop, an injector sub-loom — sold as its own part number.
Materials & specifications

What is inside the loom

These are the defaults. If your drawing specifies something different, we build to your drawing.

ConductorStranded bare copper, 0.22–6 mm² (AWG 24–10); 8–35 mm² battery and HV cables on request
InsulationTXL (irradiated PVC, 125 °C), GXL (glass braid), TPE where flexibility matters, silicone for high-temperature branches
ConnectorsSumitomo, Yazaki, Aptiv/Delphi, TE Connectivity, Molex, KET, JAE — original series or documented equivalent
TerminalsOpen-barrel crimp with pull-test record; sealed terminals with individual wire seals on exposed joints
ProtectionPVC 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 test100% continuity, short-circuit and pin-out test against the approved drawing; hipot 3000 V AC on HV assemblies
Mechanical testCrimp pull test, terminal retention, 300,000-cycle bend on hinge loops, vibration and salt-spray on chassis looms
TraceabilityWire lot, terminal lot, operator and test result recorded per unit; test record shipped with the carton
PackingCoiled and labeled per part number, returnable racks for volume, export carton with desiccant for sea freight
