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

  • Troubleshooting Trailer Brake Lights not Working after 4-way Install on a 1998 Nissan Frontier
  • The first thing I would do is test the circuits of the 4-way on the Tow Ready Wiring Harness part # 118362 with a circuit tester like part # PTW2993. This will tell you if the problem is on the vehicle or the trailer. To see how this would be done check out the video link I attached. If the voltage is there like its supposed to be then you know the problem is on the trailer wiring. The first place to check is the grounds of the light assemblies. A weak ground can cause taillights not to...

  • Troubleshooting Factory Trailer Wiring on 2012 Nissan Frontier
  • Thanks for all the details of your troubleshooting efforts with the trailer wiring on your 2012 Frontier. Since your old fuses were not blown and your new fuses that have the indicator lights did not light up this tends to suggest that your tow package relays are not working and this is why power is not making it to the fuses or to the trailer connector. On the passenger side of the engine compartment close to the windshield are both a fuse box and a smaller fuse/relay box. Both are shown...

  • Troubleshooting Powered A-Frame Jack that Clicks and Wont Work with Good Battery
  • Based on your description of the problem it sounds like your jack has a bad ground connection since you said the battery is good and it's clicking which typically indicates that the jack motor can't draw enough power to operate. This jack part # EJ-3520-BBX grounds through it's mounting hardware so you need to make sure it's attached to a clean metal surface (it should be) but also that the main ground harness of the trailer wiring is also connected to a clean metal surface on the trailer...

  • 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 Brake Controller that Flashes When Connected to Trailer
  • It sounds like the problem is corrosion on the trailer 7-way brake output circuit which is causing the controller to only show an intermittent connection. Try cleaning off this pin on the 7-way with some fine grit sandpaper. 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. Using a circuit tester like part # PTW2993, you should get output to the controller side of...

  • Trailer Left Turn Signal/Brake Light Not Working when Connected to a 2015 Nissan Frontier
  • The first thing to check is if the problem is on the truck side or trailer side. Disconnect the trailer and use a circuit such as # PTW2993 to test the connector of the truck. If the brake light/left turn signal are not working at the connector, then the issue is on the truck side. Your 2015 Nissan Frontier could be missing a relay for the left turn signal/brake light circuit. The relay should be under the hood. If missing, you could use one of the blue relays from the Curt Relay Kit #...

  • Missing Relays for Trailer Turn Signals on 2012 Nissan Frontier
  • It sounds as if you might be missing two of the relays. The relays are available in the Curt Relay Kit # C57000. The blue relays control the turn signals, and it sounds like that's what you're missing. I've linked you to a photo showing where the relays are usually located, and also to a video showing the same thing.

  • Is Prodigy P2 # 90885 Brake Controller on 2015 Nissan Frontier Supposed to Have Power w/ Vehicle Off
  • It is indeed normal. After about 10 or 15 minutes of inactivity, the controller will go into a sleep mode where there is almost no battery draw. In order to run down the battery to the point where it would cause problems, the vehicle would have to sit for several months. The controller is directly connected to the battery as a safety measure. It's very important that the controller isn't inadvertently turned off-if it were turned off or unplugged and you forgot to plug it back in, it could...

  • Troubleshooting A 7-Way Trailer Wiring Harness That Isn't Sending Braking And Turning Signals
  • Since the T-One Vehicle Wiring Harness with 7-Way Trailer Connector # 118281 is a quick plug and play style connection I would first check the pins in each connector and ensure none are bent, missing, and that there isn't any debris blocking the connections. You can use some Dielectric Grease # 11755 to ensure a proper and waterproof connection. Next you can test the pins at the 7-way using a tester like the # PTW2992 to see if the signal is being sent or is getting lost somewhere before...

  • Troubleshooting No Turn Signals on Trailer Towed by 2015 Nissan Frontier
  • If the factory 4-pole trailer wiring on your 2015 Nissan Frontier is not providing turn signals the issue could have several causes. It is possible the factory/dealership did not install the required relays in the Frontier. We offer the relays by themselves as part # C57000 and as part of a complete wiring harness kit # C56225. You could also have a blown fuse in the power distribution box; this you can check by taking off the lid and finding the fuses related to trailer lights. Check...

  • Troubleshooting Trailer Running Lights Not Working with 2018 Nissan Frontier
  • On certain Nissan vehicles like yours a 4th blue relay is sometimes needed to activate the trailer running lights circuit. This appears to be the case with your 2018 Nissan Frontier. The blue relay that you need is included in the Curt Relay Kit # C57000 and the harness you need to access to plug the relay in is indeed located in the cab behind the dash to the left of the steering column. I have attached an image that might help.

  • Running Lights Not Working when Using a T-One Vehicle Wiring Harness On a 2009 Nissan Frontier
  • The first thing I would do is check the fuse box on the vehicle and make sure that there is not a trailer tow package fuse blown. There is usually a legend under the lid on the fuse panel to find which fuses to check. Next I would check the connector on the vehicle, visually and with a circuit tester, item # 3808. If there is no tail light wire ran to the connector you will need the Upgraded Circuit Protected Modulite with 4 Pole Harness and Hardwire Kit, item # 118266. This kit includes...

  • Troubleshooting LED Trailer Turn Signals That Work Only When Brake Pedal is Pressed
  • I suggest you test both your vehicle wiring and trailer lighting separately to find the cause for the lighting issue you're having. Separate testing tends to make it easier to isolate the problem. To test the vehicle's wiring you will use a circuit tester like # PTW2992. The linked video illustrates use of the tester. Have a helper sit in the Frontier to activate the lighting functions one at a time while you apply the grounded tester's probe to the appropriate pins on the wiring connector....

  • No Power on Running Light Circuit on a 2012 Nissan Frontier 4-Way Trailer Connector
  • If the running light relay is present in the in-cab fuse panel on your 2012 Nissan Frontier and you are still not getting power on the brown wire of wiring harness # 118263 then it could be the fuse associated with that relay. The fuse locations and functions are not in the vehicle owners manual so you will want to check the lids for the in-cab and under hood fuse panels.

  • Curt Venturer Brake Controller Lights Blinking on 2019 Nissan Frontier
  • Thank you for your purchase from etrailer of the Curt Venturer Trailer Brake Controller # C74VV. Since the lights (red and green) are blinking, there is indeed a short somewhere, and the brightness of the red light is not an indicator of anything specific. You'll need to do some checking as there could be a number of things causing the short; often, corrosion or dirt may be the cause of a short in a trailer connector. Check the plug to see if there is any type of corrosion built up that...

  • Hayes Engage Trailer Brake Controller Shows bF Error Code
  • The error codes shown on the Hayes Engage Trailer Brake Controller part # HA81760 can be easily deciphered by looking at the owner's manual. Per the manual, "bF" indicates the blue wire is connected to wrong place, short in wiring / connector, faulty or disconnected breakaway switch. The blue wire is the brake output wire that runs from the brake controller to the 7-way and then from the 7-way to the braking assemblies. Therefore, I recommend tracing this wire to ensure there are no shorts...

  • Running Lights on Trailer are Not Working or On All the Time Using Adapter # 37385
  • I recommend testing the 7-Way trailer connector without the adapter plugged in using a circuit tester like # PTW2993 if needed. You can use the included picture to determine what the functions should be. It is possible that something does not match up between the 7-Way and the adapter. If the 7-Way is functioning properly, plug in the adapter and test again using the 4-Way picture included. If the signals coming out the 4-Way side do not match up, you may need to re-pin the adapter. Also...
