Hey everyone, what is this plug? I put my meter to it and it has nothing going to it.

Possible to get a 12v constant to it?

Test it and find out?

do you have a rear camera installed if not I believe that may be the jumper harness for the rear camera option

4 flat connector
 

most small utility trailers that don't have brakes will connect and use this. If you turn on your parking lights you should find one of the connections is energized. with turn signals on you should find the others are for left turn, right turn.

First pic is most defiantly the flat four trailer wiring harness.

Yep, I installed one of these on my Jeep to pull a small utility trailer.

Wow some people should not own trucks.
