I have a 2015 Note SV,
I checked the entire harness, every single corner. Then I took come of the tape from the wire loom and counted the wires and colors, and traced them to their locations. I removed the intake too. I traced every wire to every fuse. Thats when I realized there was no Fog Light Fuse. there is no fuse and the fuse place doesnt have contacts either. So if you place a fuse, the current goes nowhere because there is no wire. I also opened up the Relay box, which contains the Fog light relay and fan relays. There was 2 relays, as per description, However, the wires coming out the "fog lights" relay were FAR TOO SMALL to take any significant current. I'm a electronic Technician of 8 yrs, And about to finish my Bachelors in Electrical Engineering. I know what I'm talking about. I also tried to turn on the fog lights, and feeling the relay. nothing. NADA.
No fuse, No wires, No Relay, No connector. Nissan decided to Fuck everyone who doesnt pay up for 1 fuse 1 relays and 10 ft of wire. Sorry but I dont think you will find it if you have a 2015 model. I spent 7 hrs today and never found it. The circuit doesnt exist.
