I'm not sure if this is the answer you are looking for or if we are missing some pertinent info but the trailer electrical connection is a 7 pin, round connector just a bit to the right of the hitch pin receiver.
Thanks Metaxa! I am actually installing the 7-pin socket. Nissan has “built in” the necessary wiring so you don’t have to run wires yourself. There’s a connector under the dash and another connector in the rear. I did find it! There’s a connector on the frame beneath the evap canister! Mine is already connect to a four pin
