Fun, somewhat related, fact. For a long time (not sure about now), the high-voltage connectors in Tesla were made by (but not labeled) Yazaki. Made in Japan.

But the QC tests to Yazaki's deisred level didn't exist yet, and Tesla did their own tests. And Tesla was maximizing it's "Made in the US" stance, which either goes by weight or components.

So Yazaki was secretly making unlabeled high-voltage connectors in Japan, selling them to Tesla, who could then test them themselves and claim falsely the source of production.
