Help! I have just installed a new hitch on my wife's 07 SE, but my trailer has no running lights. Everything else works as far as turn signals and brake lights. This hitch, plug and relays came from Nissan dealer. I used an adapter to go from 7-pin connector to 4; could this be the problem? It was working on my truck.
I followed OEM directions that came with hitch from dealer. It said nothing about relay under the dash. For electric trailer brakes it mention jumper harness connection under dash. I talked with service department at Dearlership and he said the problem must be with the relays being in the wrong spot. I told him they were only 3 spots open under the hood, 2 for the small relays and 1 for the large relay.
This trailer light topic and all related threads should be a sticky post containing the ultimate solution.
As far as the exact placement of that final relay under the driver's side dash? An excellent solution was posted by Roadhog here . Of course, I wouldn't have gotten very far without the important information from scr38.
