Troubleshooting Running Light Circuit of Trailer wiring Not Active When Fuses are Good
Question:
When I plug in a trailer 4 ways and brake lights work, no running lights. I’ve replaced the plug, checked my fuses, still no running lights. It’s not the trailer, I plugged it into another truck and they worked. Please help

Have you checked the pins of your trailer wiring for dirt or corrosion? The most common reason for the issue you are having is dirty pins on the connectors. What you'll want to do is use sandpaper to clean the pins off and that should get the problem addressed.
I attached a couple help articles on trailer wiring for you to check out as well.
