I recently purchased a 2010 Nissan Xterra and am trying to figure out how to wire the trailer. I got the harness from Nissan and installed it with a seven pin connector on the back bumper. I also purchased a five to seven pin adapter on eBay and have everything I need, right?? Not so, I have a four pin connector on the trailer. My question is simple, what do I do now?? Do I rewire the trailer with a five pin connector (what purpose would that serve) or what is another alternative. I have not had the boat and trailer that long and wouldn't mind rewiring it anyway because it is kinda old but is there another easier alternative for the time being so I can wait until the winter to rewire the trailer?? I have not tried the lights and might need to do so before making and informed decision but from other discussions it seems if I use the four pin my running lights will not work. http://www.bassboatcentral.com/smileys/mad.gif http://www.bassboatcentral.com/smileys/roll.gif
