Tacoma interior quiz

Cleaning out my '12 TRD DC after recent professional leather interior install. Found the following two black trim pieces in the rear door cubby. For the life of me, can't see where they go, if they are even needed anymore.

Before I contact the installer, would someone please enlighten me from my brain lapse?

 

I have no idea, but I'll take a stab at it. It looks like a piece that would typically cover the seat rail, where it is bolted to the floor. however, if that is it, I would've thought they'd be grey and not black. Soooo, I'll make a secondary guess and say that it looks like they would go somewhere behind the rear seats.

 

do you really need it?

 

They are preformed to fit exactly somewhere- Look around for a fit, or maybe look at another truck with the same trim package to see where they are installed...

 

Fold the rear seats down, I think they go on the back corners, behind the rear seats.. I think....

 

yep that...for sure
