How to Complete the 12 Volt Accessory Circuit on the 7-Way of a 2013 Nissan NV 2500

Question:

I have a 2013 Nv2500 with factory tow package. I have installed a brake controller with the plug and play wiring harness. All brakes, lights and controller are working as they should. My problem is that I do not have power at the 12 volt lead on the 7 way. I am sure that there is either a fuse that I am supposed to install or a connection that I need to make somewhere. Can anyone help me?

First thing I would do is check the back of the 7-way to see if there is a wire attached to the 12 volt pin of the 7-way. This will be the 1:00 pin if you are looking into the connector from the front. If a wire is there then most likely you are missing a tow package relay under the hood.

If there is nothing ran to that circuit, (or if you want to just fix the problem without any guesswork) you can run a length of 10 gauge wire from the 12 volt circuit pin of the 7-way through a 40 amp breaker to the positive post of your battery and call it a day.

For wire you would want the part # 10-1-1 sold by the foot and for a breaker you would want the # 9510.
