Expert Reply:
Your 2018 Nissan Pathfinder does require a couple of blue relays to be installed to fully activate the tow package so that the turn/brake signal lights work on the trailer when connected. The relay harness on your Pathfinder gets plugged into a factory port at the rear of the vehicle behind some paneling on the driver side. I have attached an installation video that you can use for reference where we use the Tekonsha T-One Wiring Harness # 118670, which includes the needed relays.
The relays by themselves can be obtained with part # C57000.
