I just installed the Murano factory trailer wiring harness on my '06 Murano. If one follows the directions, which I belive I did, I can't see how anything can foul up, but I am having a problem with power going to the taillights even when the ignition is off and the lights are in the off position. Directionals and brake lights work fine, but the harness remains hot with the ignition off. Has anyone encountered this problem? Looks like a lousy relay, but I would hate like hell to spend another hundred bucks. I have been wiring trailers for over 20 years and this is the first time I have ever encountered anything like this.
