  • Trailer Connector Not Working on 2014 Nissan Pathfinder
  • The Hopkins wiring harness you purchased for your 2014 Nissan Pathfinder is for models that came with a factory tow package. Since your harness is not working the vehicle probably does not have the factory tow package so it is missing some key components. Using trailer wiring harness # 118670 will provide these missing components and allow the trailer wiring harness to work. The jumper harness installs in the rear most part of the Pathfinder under the floor. I have linked the instructions...

  • Troubleshooting Tow Ready Trailer Wiring Harness # 118266 Install
  • Okay, I think I have a suspicion about what might have happened.... the jumper harness should be plugged into an EMPTY connector, as shown in the photo I've edited for you. You shouldn't have had to unplug anything to plug the jumper in. What you've unplugged is the wiring harness for the passenger side door. Did your vehicle already have a 4-pole connector on it, or did it have no connector at all? If it already has a 4-pole, the jumper harness is already in place behind the toe kick...

  • Troubleshooting Factory Brake Controller Error 0.9 on a 2016 Nissan Titan XD
  • That is an interesting dilemma; for the Prodigy P2, the 0.9 error is one that will flash a few times a second or steadily display. When this occurs it is because the controller recognizes that the trailer is connected but the P2 loses connection to the battery ground. First place to start is the connections. I would first check the trailer connector for any corrosion both inside and outside of the connector. Corrosion can cause all type of errors including the 0.9 you are getting. ...

  • Troubleshooting Ground Problem on Trailer Towed by 2004 Nissan Frontier
  • If the main ground has been improved and you're still having the same problem, check the points where the taillights themselves ground. This is a pretty common problem. Things work well (or fairly well, in your case) until the running lamp circuit on the trailer is turned on. At that point, the lighting is pulling the maximum amperage and that's where a ground problem will show itself. Each lamp should either be grounded via a separate ground wire to the trailer frame or by it's mounting...

  • TroubleshootingTrailer Running Light Issues on a 2006 Nissan Titan Using Factory Style 7-Way # 30608
  • it sounds as if one of the relays is not in the correct location or a fuse is blown. I would double check the owners manual to determine the location of all the towing relays and fuses and see if everything is in the correct spot and in good working order. I have included a link to the installation instructions and a video showing installation on a 2006 Nissan Titan for reference. There could be one additional relay needed. If you look under the dash, and to the left of the steering column,...

  • Why Am I Getting Only 4.5V To My Running Lights?
  • The running lights draw more power so a weak ground could be preventing the full draw. I would go over your grounds and then test your wires with this tester # PTW2993 again.

  • Troubleshooting Blue and Black Wire Switched on 2011 Nissan Frontier
  • The blue electric brake wire and black 12 volt power wire mix up is on the vehicle side of your 2011 Nissan Frontier. The factory tow package connector on a few of the Nissan Xterras, Frontiers and Pathfinders from 2005 to 2012 had this issue, although it is uncommon. In order to fix the issue, I recommend cutting the two wires on the Tow Ready Wiring Harness # 118267 a few inches back from the black connector. Once this is done, switch the wires (black to blue and blue to black) and butt...

  • Troubleshooting Brake Controller that Says Not Connected to Trailer
  • Since your trailer's brakes worked on another truck that would indicate that the problem is on the truck side of the equation. First and easiest thing to check is to check for corrosion on your truck's 7-way. Some fine grit sandpaper can easily remove any corrosion that would prevent the connetion from being made. Testing the brake controller is fairly easy. Sever the blue brake output wire near the brake controller leaving enough room to reconnect it and then apply the manual slide....

  • Trailer Wiring Harness Installed on 2009 Nissan Versa Causing Brake Lights To Stay On
  • If I had to guess, I'd say that there's most likely a short circuit in the converter box. You can confirm this by disconnecting the 12-volt connection at the positive battery terminal that leads to the converter box. If this fixes the problem, it confirms that the converter box has shorted out and needs to be replaced. You should be able disconnect the connectors by pushing on the release tabs then pulling the connection apart. For a replacement, I'd recommend the Tekonsha # 118545 T-One...

  • Trailer Running Lights Not Working When Connected to a 2006 Nissan Frontier
  • First, you can verify if your 2006 Nissan Frontier came with a factory tow package by having a dealership run the VIN number to tell you what options it came with. If it did come with a factory tow package, it could be that the relays associated with the tow package running lights needs to be replaced. If it did not come with a tow package, then that relay may be missing. You can check the locations of the relays in the owner's manual. You can use a circuit tester like # PTW2993 if needed...

  • Troubleshooting 2018 Nissan Frontier without Trailer Running Light Circuit Functional
  • You do need to install that last blue relay you have. For whatever reason Nissan likes to randomly leave this circuit open and not include the relay to activate the trailer running light circuit. I have attached an image of this relay location along with a helpful installation video that you can check out as well. Please let me know if the issue persists and I will be happy to look into this further.

  • Troubleshooting Curt Venturer Brake Controller on 2008 Nissan Xterra with No Lights
  • I spoke with my contact at Curt and he said it sounds like a problem with the wiring on the trailer, probably a bad ground. His advice was to make sure the trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean and corrosion free bare metal surfaces. If there is anything between a light ground and the metal trailer frame or if...

  • Troubleshooting Trailer Turn and Brake Lights Not Working with 2017 Nissan Titan
  • If the trailer turn/brake signals aren't working with the Hopkins 7-Way on your 2017 Nissan Titan then most likely you are just missing a couple of relays. If your Titan isn't equipped with the factory tow package we recommend the Hopkins # N40975 that includes the relays but they can also be obtained separately with part # C57000. The two small blue relays are needed to activate the turn/brake signals. I have attached the installation instructions and a video that specify where they...

  • Troubleshooting Trailer Lights After Installing Trailer Connector on 2005 Nissan Armada
  • See the video I've linked of the relays # C57000. The video shows a trailer connector being installed on a 2005 Nissan Armada like yours. If you skip ahead to about the 1:50 mark, you'll see the relays being installed. Your Armada will only use two relays, one blue and the brown. The other blue relay isn't used. If you already have these installed correctly and the left-hand turn signal and brake light isn't working on your trailer, use a circuit tester, like # PTW2993, and test the...

  • Troubleshooting NC Error Code on Brake Controller when Trailer is Plugged In
  • The NC code means the controller is not seeing a trailer connected, so the brakes will not work. You will want to clean the connector with some sandpaper specifically at the 5 o'clock pin position as corrosion can cause a trailer connection to not be seen. Do the same on the corresponding trailer connection and then use some dielectric grease like # 11755 to keep moisture and debris out. If you still get no connection, then you will need to test the brake control pin at the 5 o'clock...

  • Troubleshooting Electric Brakes Locking Up With 2007 Nissan Frontier Using Harness 118266
  • The issue with the brakes locking up is not a faulty relay. The electric brake and battery charge wires in the main harness are reversed on all Nissan Frontiers that requires the use of Harness # 118266. We have a help article about this issue that I have linked for you, which describes the exact steps you will need to take in order to isolate the problem and make a simple repair.

  • Turn Signals on 2007 Nissan Titan Not Working with Replacement 7-Way Trailer Connector # 30955
  • The item you selected, 30955, does not have the relays included to activate the tow package on your vehicle - thus no turn signals. You need # N40975, the Factory Style 7-Way and 4-Way Flat. This item has the relays you need for the activation of the factory tow package. I also recommend using a circuit tester like # PTW2993 to test your 7-way on the vehicle end for proper function. The yellow wire is the left turn signal, and the green is the right signal. These are also your brake lights....
