When it comes to troubleshooting The T-One Vehicle Wiring Harness for Factory Tow Package - 7-Way Trailer Connector # 118273 on your 2014 Nissan Pathfinder you would first need to replace all the relays in the harness. It sounds like a fuse overloaded somewhere. I checked your vehicle's manual and can not find the fuse locations so I can not give you the location to look at.

If all the fuses are good, then the next step would be to use The Circuit Tester # PTW2993 and check the wiring functions at each connector.( also make sure all pins are not bent or broken). Trace the wire back probing it every few feet to locate the short. You can replace the wire using the # 16-1-1 as needed.

I attached a review video link below.
