Wiring Harness for A regional distributor in the Middle East

A regional distributor came to us with a wiring harness programme for the Middle East. 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

  • Packing that arrived crushed at the port
  • Premature wear on the first batch
  • A specification nobody had written down

What was specified

PartWiring Harness
ClientA regional distributor
Marketthe Middle East
Volume10,000 pieces across 6 specifications
Base materialPowder Coated Steel
Sampling rounds4
Delivery window6 weeks from PO to ex-factory
ComplianceSAE J431

How it was resolved

  1. The specification was rebuilt around Powder Coated Steel and the tolerance locked before bulk.
  2. A pre-production sample was approved and kept as the golden reference.
  3. Production ran with in-line inspection and a mid-run photo report.
  4. Cartons were packed to the client's own barcode and ratio specification.
  5. Documentation shipped with the goods instead of after them.

Result

  • 10,000 pieces delivered inside the 6-week window.
  • Unit cost held within 4.5% 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

Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.

Planning something similar?

Send the specification you are working to and we will confirm what we can match, what we would change and why.
