What Is LEONI Doing Now? A Wire Harness Buyer’s Total-Cost Lesson

Posted on Wednesday 16th of September 2026 by Rowan Whitaker

The quote that wasn’t cheap

In November 2020, I signed a purchase order that cost my employer far more than the number written on it. I was eight months into a sourcing job for automotive wire harnesses and cable assemblies. We needed 1,200 sub-harnesses. One established harness maker quoted $19.10 each. Another offer came in at $16.20. The connector layout looked the same. The wire spec looked the same. I calculated a saving of about $3,480 and signed.

The supplier was not the problem. My buying logic was.

Incoming inspection found crimps that failed pull tests and terminals that had not seated correctly—roughly 340 pieces out of 1,200. The rework bill was $5,620. That did not include extra freight, engineering hours, or the week we lost on the production line. My weekly report looked good. The final cost didn’t.

Unit price tells you where an order starts. Total cost tells you where it ends.

After that, I stopped comparing quotes on price alone. My worksheet now includes tooling, logistics, inspection, documentation, the realistic chance of rework, and the cost of delay. It sounds like extra work. It is. But it turns a supplier conversation into a numbers conversation instead of a hope conversation.

So, what is LEONI doing now?

In January 2024, a plant manager in Egypt forwarded a request for a new harness family and added a note in the margin: “What is LEONI doing now? Are they still building wire harnesses after all the ownership changes?”

It was a fair question. The internet gave a messy picture. Search LEONI holdings and you get corporate structure from different years. Search LEONI networks and you get cable and connectivity pages that have nothing to do with a vehicle harness. Search LEONI wire harness or LEONI Egypt and you get closer to the part we were actually buying.

The ownership story at LEONI has shifted in recent years. That part is public knowledge. But I was not buying shares in the holding company. I was buying wire harnesses, and that decision belongs at the operating level—at the plant, not at the press release.

So I asked LEONI Egypt to show us what a qualification review needs: valid IATF 16949 certification, a manufacturing scope that matched our harness family, and recent test documentation. That is a more useful answer to “What is LEONI doing now?” than any headline.

The same cost logic, applied to LEONI Egypt

When the quotes came back, LEONI Egypt was not the lowest. The gap was roughly 14 percent below their number on the cheapest option. A few years earlier, I would have stopped there.

Instead, we added the same rows I started using in 2021. What happens if one lot needs 100 percent re-inspection? What happens if a terminal condition is found after the harness is installed? What does an hour of line downtime cost when the line stops? Once those rows are in the comparison, a low quote starts to look less safe.

The LEONI Egypt response also felt different in a practical way. It came from a quality engineer, not just a sales manager. It included the plant’s scope of approval and answered the traceability questions directly. I am not saying that makes LEONI right for every buyer. It made them credible for this buyer.

We placed a pilot order. The result was unremarkable, which is the highest compliment a harness order can receive. Lots matched the purchase order, test reports matched the lots, and the invoice matched the quote. That is what total cost thinking is supposed to buy: boring predictability.

The lesson I keep re-learning

I keep coming back to the same point. People ask “What is LEONI doing now?” as if the answer will tell them whether the supplier is safe.

For our purposes, LEONI is doing what a wire harness supplier needs to do: manufacturing cables and wiring systems to automotive specification, supporting the documentation, and delivering on schedule. But the safer question is the one from November 2020: What will this supplier do when something goes wrong? The answer to that question is where total cost separates itself from price.

That lesson is based on my own experience with mid-volume automotive-grade harness orders. If you are buying commodity cable by the reel or building a data-network project, your cost lines will look different. The habit is the same. Unit price is the starting point, not the decision. It took a $5,620 rework bill to teach me that, and I still have to remind myself every time a quote looks beautifully low.
