Should Running Light Circuit on 7-Way Be Active When Vehicle is Plugged In
Question:
Should the power and running lights be on any time I connect to my running truck? Or should the running lights only come on when I turn on the truck lights?

It sounds like you're having some issues with your trailer wiring harness. In regards to a seven way trailer wring harness, the battery charge line circuit should be powered either at all time or whenever the vehicle is running. This is the only circuit that should have power under these circumstances. The trailer running light circuit will only have power when the running lights in the vehicle are turned out. This can be verified using a tester like the Pollak 7-Way to RV Socket LED Circuit Tester part # PK12741. If you have any other scenario then you'll likely need to do some troubleshooting. I have attached a help article for you to assist with this.
