sounds like the plugin may be your problem,if it had a blown fuse nothing would work.

Thanks for the reply but on another site I got my answer-- is was Fuse #42 under the hood. I changed it and now my running lights also work. But again thanks for the reply. I knew it must have been a fuse because when I connected the trailer to my sons truck all the lights worked including the running, but on mine only the brake and signal lights worked.

Try 25 AMP fuse number 100. It controls brake lights and turn signals. Running lights are usually Number 26

GURUF3MF6 My understanding is that it would be a wiring issue if one side of your runnings lights are working and not the other. Either the main power wire (brown) or the ground wire (white). if they are on their own set of white wire it might not be properly grounded. If they all ground right to the trailer itself then most likely it's a break in your brown power wire.
