My pickup is 1 month old and I hooked up to my airstream for the 1st time yesterday the brakes would not release, right turn signal stayed on even after I shut the truck off. Unconnected the light cable brakes roll and the turn signal shut off. Took a tester light to it and it appears that each of the wires need to rotate counter clockwise one position to work properly. Constant power is where the right turn signal should be as an example. I have never had a problem with the trailer and any other vehicle we have used to tow it. Is this a problem from the factory? If so how do I unpin and move?
