Wiring Harness for A logistics company in Oceania
A logistics company came to us with a wiring harness programme for Oceania. The brief was ordinary and unforgiving at the same time: a fixed launch window, a landed cost that had to survive freight and duty, and a part that had to match an existing sample. This case records what was specified, what went wrong in sampling and how the bulk order landed.
The starting point
- A specification nobody had written down
- Lead time that slipped twice before bulk started
- Inconsistent hardness between lots
What was specified
| Part | Wiring Harness |
|---|---|
| Client | A logistics company |
| Market | Oceania |
| Volume | 5,000 pieces across 6 specifications |
| Base material | ABS Plastic |
| Sampling rounds | 4 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | ECE R90 |
How it was resolved
- The specification was rebuilt around ABS Plastic and the tolerance locked before bulk.
- A pre-production sample was approved and kept as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.
- Documentation shipped with the goods instead of after them.
Result
- 5,000 pieces delivered inside the 5-week window.
- Unit cost held within 3.0% of the original quotation.
- Inspection-related rejection stayed under 1.5%.
- The specification is on file, so reorders reproduce the approved sample.
What we would repeat
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.

Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
