What is this?
I would go right back to the dealer and insist they tell you what it is. That might be something the dealer installed as a security measure for the lot. If they can't produce a good enough answer for you, however, tell them they can have their truck back, since now you don't trust them and go buy another one elsewhere.
Looks to me to be a switch for accent lighting. Looks like they were part way installing it & never finished for whatever reason. I'd take it back & find out what its there for, its pretty unacceptable to do that without your knowledge or consent. I'd have them either replace that trim or hook up whatever it was if its something you would ike
Everyone, thanks for all the replies!
