Hey Robert,
Yes, if anything were to happen in the harness, a fuse blow or removed the trailer lights will only be effected. The wiring harness like # TK73VR fuses protect the vehicles circuit incase anything were to happen. So worst comes to worse your trailer lights will only be effected in that event.
What kind of trailer are you towing?

Hey Robert, did you find the information you needed about the wiring harness and how it affects your trailer lights? I'm asking because understanding this could help others with similar questions about their trailer setups.
