Okay, I think we need to start at the beginning. I am going to attach a wiring schematic for the trailer wiring. What I need you to do is confirm that all the correct color wires indicated are going to the correct pin. The pictures are indicated by letters. On the connector you installed, they should be there to follow.
Let me know if this is how it was done. Also, let me know if you had to wire the truck as well as the trailer. Many of these trucks had a factory connection already installed.
