Re: WTF is this trim part found under passenger seat?
It could also be from where the transmission lock override is, try in front of the seat on the centre console next to the gear shifter , in australia this cover has a pink lever behind it, not sure where in the world you are. But could just be an extra from the factory, i found my cigarette lighter behind the carpet cover on the back seats, while i was there i noticed a missing nut so i fixed that up while i was there also....
