• Trailer Brakes Lock Up when Trailer is Plugged into 2015 Nissan Xterra
• The issue you are describing comes up now and again with certain Nissan vehicles. Apparently, depending on which plant the vehicle was built in, the brake output wire and the 12 volt power wire are reversed on the vehicle wiring harness. Basically to fix the problem all you have to do is swap the blue and black wires inside of the Curt harness 7-Way part that plugs into the vehicle # C56226. There are a couple of ways to do this: Repair Option 1 This option is the best for the longevity...

• 7 Way Trailer Plug Will Not Stay Seated In the Vehicle 7 Way
• This can be caused by a few things, but as you have enough slack in the wire, it is most likely just one of two things. The door flap, for the lack of a better way to put it, on the 7 Way plug on the towing vehicle snaps down on a tab on the 7 Way plug coming from the trailer. These can break off which causes them to come uncoupled. If this is the case, the 7 Way trailer end will need to be replaced with something like the Optronics # A7WCB. But it could also just not be seated all the...

• Tekonsha PowerTrac Light Went Out
• If the light on the Tekonsha PowerTrac Electronic Brake Controller # 39523 if off then that means that it is reading that the trailer is not connected. It is more likely that there is a problem with your wiring somewhere than the controller failing at this point. Before troubleshooting you will want to make sure that the connector on both your tow vehicle and your trailer are clean and free of debris and corrosion. You can start off by testing the pin in the 5 O'clock position on your...

• Troubleshooting Tekonsha # 90885 P2-Brake Controller Install on 2014 Nissan Xterra
• First, unplug the # 3050-P connector from the rear of the controller, and use a circuit tester like part # PTW2993 to test the pin fed by the black wire. If you're getting power, make sure the pin is correctly aligned. If you're not getting power, unplug the harness from the connector under the dash, being sure to note which pin the black wire connects to. Use the circuit tester on the pin that the black wire connects with. If you get power on the connector, check the end of the 3050-P...

• Relay Recommendation to Activate Trailer Running Lights on a 2005 Nissan Xterra
• It sounds like your 2005 Nissan Xterra is missing one relay (or it has gone bad), that is traditionally found under the dash to the left of the steering column. There is a socket there to plug in the relay that will activate the tow package tail lights. You are correct that the Curt T-connector # C56225 has the relays, the replacement blue relay is also included in the Curt Relay Kit # C57000.

• Troubleshooting Redarc Tow-Pro Liberty Brake Controller on a 2006 Nissan Xterra and 2022 Frontier
• The Pigtail # RED39FR that you received with your Redarc Tow-Pro Liberty # RED24FR should match the functions on the OEM plug of both your 2006 Nissan Xterra and your 2022 Nissan Frontier. If the pins aren't matching up with the functions then either the wiring adapter you have was wired incorrectly, or your vehicle wasn't wired correctly. Some other things to look into is making sure the wiring isn't damaged anywhere and causing the functions to cross over either in the connector or on...

• Trailer Lights Not Working on Trailer Towed by 2005 Nissan Xterra
• You will want to check the fuses and relays associated with the tow package to see if something needs to be replaced. It very well could be that some of the relays are missing or bad on your Xterra. In my research, I could not find a fuse location for you. You can use the vehicle owner's manual to locate all of the fuses and relays that are related to the tow package. Some may be under the hood and others may be inside the cab of the vehicle. If you need some, you can use relay kit #...

• Troubleshooting Trailer Brakes Always Locked When Connected to 2014 Nissan Xterra 7-Way
• I can help you correct this issue on your 2014 Nissan Xterra. This is an issue we have seen on a number Nissan's tow package wires. The issue is that the electric brake signal wire and the 12V battery charge wire are reversed in the main vehicle harness. This is the reason that the # 118267 harness you purchased has a constant 12V signal on the brake controller output circuit. Since there is constant power to the brake controller output in, there should be no signal on the 12V battery...

• Troubleshooting Curt Trailer Wiring Harness Install on a 2000 Nissan Xterra
• The red wire of the Wiring Harness part # C56496 that you referenced should be run to the brake light circuit of your 2000 Nissan Xterra. If you are missing that connection I would recommend you verify that the other wires are securely connected to the correct circuits. Especially the black wire that needs to run to the positive terminal of your vehicle battery. If this connection isn't made, or the fuse isn't installed in the fuse holder the converter will not work. I attached an install...

• What is the Typical Wiring for a Tow Vehicle Side 7-Way
• If you check out the picture I attached of a typical 7-Way you can see that the 12V Power is typically on the 2 o'clock position pin and the Brake Controller Output is typically on the 4 (or 5) o'clock position pin. You can verify this with a Circuit Tester # PTW2992 while applying full power with the manual override lever on your brake controller. If your trailer 7-Way is not wired in this manner then I encourage you to swap the wiring on your trailer before the wiring on your 2007 Nissan...

• 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...

• Trailer Brakes Lock Up After Installing Replacement 7-Way Wiring Harness on a 2005 Nissan Xterra
• It sounds like the brake output circuit is getting 12 volts of power all the time. This could be due to a mis-wired connector or a mismatch between the trailer connector and the new 7-Way. There could also be a bent or broken pin somewhere in the new harness or where it connects to the vehicle. And finally, corrosion on the trailer connector pins can cause a short from the 12-volt pin to the brake output pin. Let's take a look at how your trailer side connector is pinned out. I have included...

• Trailer Running Light Circuit Does Not Work On 2006 Nissan Xterra 4-Way Trailer Wiring Harness
• You are most likely missing one relay or fuse to control the running lights. Use the vehicle owners manual to find the locations of the relays/fuses associated with the trailer wiring. The one that is for the running lights could be missing or it could have gone bad. It is also possible that there is another relay required in the in-cab fuse panel that you will need to obtain from the dealer.

• Is There More than One Way Nissan Vehicles Install Trailer Wiring Using Factory Connections
• Nissan tow package wiring on vehicles like your 2014 Nissan Xterra installs in a few different ways, but since you were able to have the kit work at one point yours was installed properly. The harnesses and relays are just sometimes in a few locations like you mentioned. Sometimes behind the kick panel on passenger side, sometimes at the rear of the vehicle, and sometimes closer to the driver side of the vehicle. What issue are you having? Most likely issues with this setup are related...

• Troubleshooting Trailer Lights After Installing Wiring in 2006 Nissan Xterra
• Thank you for your recent purchase from etrailer and for detailing your troubleshooting efforts with your wiring harness kit # C56225. Since you have applied a circuit tester to the 4-pole harness and confirmed that it has the correct output, and that it works fine with a second trailer, odds are that your issue is within the wiring on the first trailer. It is possible for corrosion to build up inside the connectors or on their contact surfaces. Even slight greenish or whitish discoloration...

• Installed Trailer Wiring on 2006 Nissan Xterra and Trailer Lights Wont Turn On
• I would first start off by making sure that all of the appropriate relays are in place. The turn signal and brake light relays will be in the fuse box under the hood of your 2006 Nissan Xterra. You can check the owner's manual or the legend on the panel to see their location in the box and see if they are in place and are not bad. You will also want to check the jumper harness that should be located on the passenger side floorboard behind the kick panel to make sure that it is securely...

• Converting Vehicle Side 7-Way Trailer Wiring to 4-Way Standard Wiring
• It sounds like you want to do a conversion from your 7-way to a standard 4-way trailer connection that has the 3 functions and ground. There are a couple different options for you that don't require much if you just need the 4-way connector for a trailer. You can use the Pollak 7 Pole to 4 Way Connector Adapter # PK12716 for the easiest connection. Your 2001 Xterra didn't come with a factory 7-way so you may find there is a 4-way plug connection behind your 7-way that you can simply...

• No 12 Volt Power to my 7-way Connector on my 2007 Nissan Xterra
• Yuor 2007 Nissan Xterra is set up where your key needs to be in the accessory or run position to activate the 12 Volt power.
