Ok I have searched the topics but cant find anything similar to the problem I am having hopefully someone can help me.
I have a double pwc trailer that I smashed the right tail light off of due to m expert backing skills. after I hooked up the new light it doesn't work when brakes are pressed or turn signal is activated. The left side works fine along with running lights. At first I figured it wasn't grounded properly but when I turn on the headlights it lights up but turn and brake don't work. I hooked up another trailer and it has the same problem which leads me to believe that its the wiring in the xterra. So here's my question, Is there a separate fuse for just the right brake and turn signal in the trailer harness that might have blown? or something more serious?

No fuse.
My guess is that the wires may be crossed at the new light.

Its not the trailer I tested the 7 pin receiver on the x and its not getting power to the right turn signal. The left turn signal works fine. Can anyone help me?
