You know, I had the same problem on my Frontier. Plugged in the OEM harness & relay harness that was in the kit I bought from Nissan and everything worked except the taillights when plugged into my boat trailer harness. After a lot of testing by my friend, who is a former Nissan technician, I eventually ran a separate wire from the harness to the license plate light wire and now the lights work fine.I have a 2010 Xrerra, I bought a pigtail to plug into the trailer wiring connection on the back of the drivers side, ,all was good, now the taillights on the trailer won't work, Idon't seem to begetting any voltage to the oem connector any suggestions?
Thank you very much. I was not even aware of that fuse panel and I have owned 2 Xterras prior to this. Glad the Frontier is basically an X with a bed on it.Glovebox right side fuse panel
