  • Troubleshooting Trailer Running Lights that will Work for 10 Minutes and then Shut Off
  • Sounds like your trailer is drawing slightly more than the running light circuit of your 2011 Nissan Frontier SV can handle and after a while the relay is getting hot and shutting off. Once it cools off it works again. The best recommendation I could make for you would be to convert the taillights of your trailer to LEDs to minimize the draw on the circuits. LEDs draw a fraction of what incandescent bulbs draw so your problem should stop. I attached a link to a page that has all of the...

  • Adding a 7-Way and Brake Controller to a 2007 Nissan Frontier
  • If your 2007 Nissan Frontier did not come with a trailer connector (not the connection points they would plug into) then in order to install a 7-Way you will need to install # 118266. This is the 7-Way connector and the jumper harness with the relays that install behind that passenger side kick panel. This is the correct harness if your Frontier did not come with a factory tow package. The 7-Way trailer connector does handle trailer brakes but you will need a brake controller as well....

  • After Installing Wiring Harness on 2004 Nissan Frontier Trailer Brake Lights/Turn Signals Dont Work
  • You will want to use the vehicle owners manual for your 2004 Nissan Frontier to find the locations of any fuses or relays related to the tow package wiring on the truck. It is possible that the fuses or relays are blown or missing. If the fuses and relays are in place and working then you will want to test the converter using a circuit tester such as # 3808 if you do not already have a circuit tester. The first part of the test is to test the wires going into the converter from the...

  • Installing 7-Way Trailer Connector on 2014 Nissan Frontier
  • To install a 7-way, you'd first need to install the 4-pole flat connector (if you don't already have one.) I'd recommend the Tow Ready wiring harness, part # 118525. Once that's in place, how you would proceed will depend on the trailer you're pulling. If the trailer does NOT have brakes, but just the lighting circuits, you can simply use the # 37185 adapter. The adapter would plug into your existing 4-pole, and the white wire with the ring terminal on it would ground to the vehicle...

  • Remove Plugs on Factory Wiring Harness to Install Trailer Wiring on a 2013 Nissan Frontier
  • I think the video you are referring to is the one I have linked here. The release is right where our installer is pushing on the connector with the screwdriver. You have to push in and pull down at the same time. The part you will be pushing in and down on is the cap so you are not likely to break the connector. Road grime could have gummed up the plug and connector a little so it may need to be cleaned with a few squirts of WD40 and then wiped off. You just don't want to get any WD40...

  • P2 Brake Controller Does Not Show Trailer Connected when Trailer Connected to 2011 Nissan Frontier
  • One quick way to determine if there is any issue in the wiring between the brake controller and the newly installed 7-Way is to perform 1 simple test. Disconnect the trailer. Then use a circuit tester such as # 3808 to test the brake output pn on the 7-Way while someone sits in the 2011 Frontier and applies the brake controller manual override. The brake output pin is in the 5 oclock position. If there is power on that pin when you perform this test then the issue is on the trailer....

  • Trailer Wiring Recommendation for a 2014 Nissan Frontier
  • In your case it sounds like your 1999 Nissan Frontier already had the relays installed. So for you no, it would not be necessary to use the included relays. If the vehicle has a tow package most likely the relays are already in place. If you install everything but the relays and it all works then you would be good-to-go on your 2014 Nissan Frontier. If not, then you would need to install them. The large brown relay is for the 12-volt power source for a 7-way and the blue relays are...

  • Troubleshooting Turn Signal/Brake Light, Tow Ready Harness # 118525 Install on 2005 Nissan Frontier
  • The blue relays of the Tow Ready Wiring kit part # 118525 that you installed on your 2005 Nissan Frontier are responsible for the turn signal/brake functions. It sounds like you either didn't install them yet on your vehicle or they have become damaged and need to be replaced. If you need to replace them you would need a part # 38666-1 for each circuit. I attached an install video for the # 118525 for you to check out also.

  • 7-Way trailer connector # 118267 is meant as a replacement for a 2012 Nissan Frontier that came with a factory 7-Way trailer connector. If your truck did not originally come with the factory 7-Way then it will not be fully functional. The truck is missing a jumper harness. The jumper harness is not available by itself so you would need the complete harness # 118266. If you are replacing an OEM 7-Way then it sounds like you just need to add a blue relay to the jumper harness, # 38666-1....

  • Is a 4-Wire Vehicle Side 4-Way Connector Compatible with a 5-Wire Trailer Side 4-Way Connector
  • Your trailer has what is called a wishbone harness. On a wishbone harness the running light circuit is split at the connector and will have two wires for one pin, one for each side of the trailer. This is so you do not have to run a jumper wire from one side of the trailer to get running lights for the other side. The 4-Way wiring harness # C55362 for your 2002 Nissan Frontier will be compatible with a wishbone harness, no problem.

If you were to install a replacement factory 4-Way you would not need any additional relays. The ones that work with the 7-Way also work with the 4-Way. If you choose to install a 4-Way you will have to disconnect the 7-Way because they plug into the same locations.

  • Trailer Lights Not Working with Wiring Harness 118362 on a 2001 Nissan Frontier
  • It sounds like there could be a ground issue with the main trailer ground and/or the grounds to the lights. Make sure that all the trailer grounds are attached to clean and corrosion free bare metal surfaces. If the trailer is aluminum, you may need to ground the lights with the main trailer ground instead of to the frame. Similarly if it is a tilting trailer or if it has a folding tongue then it is most likely a ground issue and you will want to change the way the grounds are run by...

  • Trailer Wiring Harness Recommendation for a 2000 Nissan Frontier SE 2 Door Extended Cab
  • The Hopkins Plug-N-Tow Wiring Harness, # 33515, and the Tow Ready T-One Wiring Harness, # 118362, are very similar wiring harnesses. Other than the fact that they are made by two different manufacturers, the only difference between these two wiring harnesses is having the ability to disconnect the 4-way flat connector from the converter box on the Hopkins harness. My recommendation would be the Tow Ready T-One wiring harness. This wiring harness is more economical in price and will...

  • What is the Correct Trailer Wiring Harness for a 2006 Nissan Frontier SE Crew Cab
  • The 2006 Nissan Frontier is going to have that plug you have found no matter how the truck is equipped. If your truck did not come with a factory tow package, there will be no power to that plug. You can test it with a circuit tester like # 3808 if needed. There are some cases where even if the relays for the tow package are not present, there could still be power at that plug because the tester only draws a small amount of power. Consult the owners manual to find the locations of the...

  • Trailer Wiring and Trailer Hitch Recommendations for a 2005 Nissan Frontier NISMO
  • Really the only definitive way to know if the relays are there or not is to check. All models are going to have that connection point under the truck. What you can do to determine if the truck ever had the factory tow package (which would include relays) would be to have a Nissan dealer run the VIN and tell you if it had the factory tow package. If you determine it does not have the factory tow package or you check and there are no relays, you will need wiring harness # 118525. If...
