I know this was discussed a few years back but somehow that thread doesn't seem to match what I see in my trunk. I'm trying to replace the TPMS control module and, based on the sedan, assume it's somewhere near the rear left taillight. But when I remove the left liner, I don't see much outside of what must be the smallest storage container in the world (maybe .5" deep). Using a mirror I peaked around the panels that support the convertible top shelf but didn't see anything there either.

Can someone please tell me where it is and how I access it?

Thank you.

James
