No 12 Volt Power on Factory Installed 7-Way Trailer Connector on a 2009 Nissan Frontier

Question:

I have a 2009 Nissan Frontier 4-d pickup with a factory 7-wire receptacle at the back. The 12v aux for charging a breakaway battery does not have +12v to it. I cant find a fuse associated with this and no mention in the owners manual. Is there a relay, fuse or wire that needs to be connected? I had a similar problem with a 2003 Chev Silverado, Had to connect a wire to a post and add a fuse. Is this a similar situation?

On your 2009 Nissan Frontier, there should be a relay and there could be a fuse for the 12 volt power circuit on the factory installed 7-Way. To find the locations you will want to look in the owners manual. However I checked a copy online and there was no specific information about the fuses/relays and what they do. This information then is most likely on the lid of the power distribution box under the hood and on the inside cover of the in-cab fuse panel.

I believe you will need a large brown relay, included in relay kit # C57000, in the power distribution box under the hood. If your truck still is under warranty, I would take it to the dealer and have them put it in for you.
