I had my trailer battery polarity reversed and it burnt my brake controller. Check your trailer battery polarity. The lights in your trailer will still work if the battery is wired incorrectly.
If everything is wired correctly, there should be no problem.
I would be pretty confident your truck connection is wired backwards though. etrailer.com has the pinouts listed.
