Trailer lights aways on

Trailer lights aways on
I have a 2011 Ford F-150 XLT. Thanks to the forum, I did take the fuses out of the glovebox and installed them. So trailer lights and blinkers work fine. I just purchased a small teardrop tailer. My problem is that the trailer lights are always on when plugged into the truck.They are on even when lights are off and key is out.
I am assuming that the problem is with the wiring of the trailer harness but I wanted to ask here first in case the problem might be with the truck. I have never had a trailer so I am unsure if the 7 prong plug is always hot. Obviously it is on my truck. Is this way it should be?
What do you think may be the problem?
Thanks,
-Sue

It looks like the truck is the problem. A circuit tester shows that when the key is turned on both the power and the lights circuit is powered. It should only show that the power is on. I also hooked up my trailer to another vehicle and it worked correctly. Some how there is a feedback circuit that when the trailer harness is plugged into the truck and the key is out, the trailer battery lights up the running lights. Now I just need to convince my Ford dealer of the problem so I can get a warranty repair.
Thanks for all of the responses.

It would be nice to have a timer or something like that to turn on the charge wire for a little bit but I suppose I could get off my duff and put a battery in the enclosed trailer to run the lights too. lol!
