Troubleshooting Running Lights And 12v Power On 2012 Nissan Titan 7-way Connector Not Working

Question:

Ive seemed to have lost power to my 7 pin connector for my trailer running lights and battery charge 12v on my 2012 Nissan Titan. Worked great back in April but this passed weekend, nothing. Ive checked what Im hoping are all the correct fuses.

If all of the fuses in your 2012 Nissan Titan look good then it is more than likely a bad relay causing the 7-way connector on your 2012 Nissan Titan to not have power to the running light or 12v power pins.

The relays are inside of the truck on the driver side underneath the dash. You should see a few blue relays, the top blue relay is for the running light circuit. Swap it with one of the other two and test your connector using a circuit tester like # 40376 to test the 3 o'clock pin on the connector to confirm if it is working now.

Now for the 12v power the relay is in the engine bay relay box and is a brown instead of blue.

To replace these relays you will need the Curt Relay Kit for Nissan Aftermarket Tow Package # C57000 which includes two blue relays and one brown relay.

I included a video of the # C57000 being installed in a 2011 Nissan Titan for you to take a look at.
