Yes its been updated in fact to prevent leaking.
I've seen pictures on this forum.
I've also seen 2-3 different designs as I've pulled like 5 of these complete trunk latch panels from the scrap yard
I was not able to find a single one with everything working lol. All of them at least one licence plate light wouldn't work. Either left or right side. So I just ran a wire from the working side to the non working side and for now I live with a light error, until I find one in a better condition.
But the ones I removed with updated design, there's no rust and they're very clean at the latch button area.
