Can anyone identify this piece of plastic? It was packed in the bag with my UMC and adapters in my CPO. I don't know if it is something official, or something the prior owner left behind. It has the "Pitch in" symbol on it, which makes me think it's trash. Maybe packing material of some kind? Also, I've heard there's a storage cubby for the J1772 adapter in the glove box - where? (I'm not near the car at the moment to look).
