I have the Curt hitch and trailer light kit installed on my PM, and tonight after I hooked up my trailer I noticed my trailer running lights stayed on very dimly. Any thoughts? The lights work perfectly otherwise. I have a 7 way camper plug but don't have the constant hot connected. I'm leaning towards a problem with that black box that you have to run the wire from the battery to.

i have the same problem, also a Curt hitch. Dealer installed. i am also guessing the ground isnt "grounded" properly, was going to dig into it this week.
and when I say "dealer installed" i think they just sent it to the U-haul center and had it put on....

Classic grounding symptom. It may be a poorly grounded light on the trailer too. Try connecting to another vehicle to diagnose that.
