It really depends on which connector type you got and the year of your truck. I have a 2017 and went with the NON-OBDII - what a mistake!!! It was almost impossible connecting the wires under the dash! I absolutely recommend the OBDII connector type.
I narrowed mine down by opening and closing the tailgate when it didn't work. If closing the tailgate fixed it, I knew it was the connection inside the tailgate.
I had the same issue with mine and this is exactly what I did. I also added a zip tie to the connector because it seemed a little loose, but it works fine now!
