I have a Ram 1500, 2016, purchased last November. While I was cleaning the truck today, I found this interior part but cannot figure out where it came from or where to put it back. Numbers stamped on the inside are 2399604 and 2399605. Thanks!

 

It covers one of the corners where the seat frame meets the carpet....I think.

 

So, there should be one on the other side? May be there but I haven't found it yet.

 

to me it kind of looks like it might be the Passenger seat jack cover.

 

Aaaah, I believe we have a winner !


Removal Of Jack And Tools (1500 Series)

To access the jack and jack tools you must remove the plastic access cover, located on the side of the front passengers seat. To remove the cover, pull the front part of the cover (closest to the front of the seat) toward you to release a locking tab. Once the front of the cover is loose, slide the cover toward the front of the seat until it is free from the seat frame.
Jack Access Cover

Remove the jack and tools by turning the wing bolt counterclockwise, remove the wing bolt and then slide the assembly out from under the seat.

 

This is exactly where it goes. I have the same piece on a '14 2500. The problem is the small plastic clip that holds it in to the seat frame broke. I have been to the dealer and several websites; but it is not represented well in the diagrams, or at all. Can someone help me with a part number to replace it. The numbers that are stamped on the back don't correspond to anything.

Thanks

 

It's in Group 22 in the parts catalog. Appears to be the same PN for every package level of 2500. Part # 1JA35DX9AB
