No I didn't get it programmed. I was under the impression that programming wasn't necessary for the lights to work. The trailer is only a small utility trailer with incandescent lights not LED. Also the turn signals work, but brake lights don't and the running lights stay on even if the lights on the x5 are off. I went over the wiring about 5x and it's definitely right. I'm just wondering if it could be the trailer light module that's faulty or maybe programming is indeed necessary.
