BOSS brand ever featured on McLaren Formula 1 car

Presumably, most McLaren fans thought Boss brand ever make a racing harness/seat-belt.

But later claimed it wrong, Boss brand just a sponsor stitch on the harness despite McLaren originally utilizing Schroth seat-belt that time.

How about other cases? Any additions?
