Video Transcript for Tow Ready Vehicle Wiring Harness Installation - 2018 Nissan Frontier

Hey everybody, Ryan here at etrailer. Today, on our 2018 Nissan Frontier we're gonna be showing you how to install the tow ready replacement four-way flat wiring harness. Before we get into that though, why don't we just check this out and make sure it's gonna work. So what this is gonna be is just a replacement harness, to replace your existing one whether it's a factory one or an aftermarket one. And the reason being, a lot of times these can just get damaged, you know corrosion and if it's out in elements all the time or maybe you left it plugged into your trailer on accident and, you know, when you go to disconnect and drive away and it rips it out or you know, there's a lot of different things that can happen, that can just cause this to get worn out. You know, maybe try to push it in wrong and this broke, whatever the case may be.

So if that happens, you don't have to deal with getting a whole entire new kit. You can get just a harness, plug it in and get going again. I want to mention though, you have to have the relays installed for your factory tow package. So, if you're trucked didn't come equipped with the, you know, with a factory tow package, you know, a four way or seven way, you'll have to get that kit for this to work. This is just one of two pieces for the whole thing so you know if that's something you need, you can always find those parts right here at etrailer.

Aside from that though, that's really about it, you know, not a whole lot to the setup. One thing I like to do is take wire loom and put it over the wire here. Just kind of cleans up our install look a little bit more. And you can also, you can secure wiring like this, or if you wanted to, you can get a four-way flat bracket and screw it to your bumper, your hitch, or wherever you want to mount it, and do something a little bit different there too. So that's always an option, but other than that at the end of the day, it's going to be a good solution for you and a quick fix for a lot of you out there that might have damaged your connector in there.

As far as getting it installed goes, I mean it's it's about as easy as it gets, you essentially plug it in, and then zip tie it up and run it over here. So, I really shouldn't run into too many issues. If you'd like to see how we did that though. Feel free to hang around. We'll go ahead and install it now.

So to begin our installation, we're going to be here, at the back of our Frontier, working on the driver's side frame rail, right here in this area where our factory connector's located. Here's our factory connector and with this being a replacement end our customer already removed their old one. So, all that's left for us to do really is plug this in. I'll route our four-way flat over to our hitch and show you what it looks like once I've done that. Got our wiring all routed up. So, I used a zip tie, secured it here, just ran it along, through here where it drops down and I have. If I can get it undone now. I just took our dust cover and put it around our safety chain opening and that's what's securing our wiring. So I went ahead and put some wire loom on over our wiring just kind of clean up the install look. Then I plugged in this tester here. That way we can check our wiring. I suggest using something like this, as opposed to plugging into your trailer because if you plug into your trailer, if it has any issues, it might mislead you into thinking it's something on the vehicle side. But with that said, we'll go ahead hop in our truck and run through the signals. I'll go ahead and turn on our left turn signal, our right turn signal, hit our brakes, and then turn on our taillights. That'll finish up our look at, and our installation of the tow ready replacement four-way flat wiring harness on our 2018 Nissan Frontier..

  • Are Relays Required to Activate the Trailer Wiring Harness on a Nissan Frontier
    On the Nissan Frontier and other Nissan vehicles, if the vehicle did not come with a factory tow package it will not have a functioning wiring harness even if one, like # 118263, is added. There will be relays that will need to be inserted to make the trailer wiring harness fully functional. If your Nissan did not come with a factory tow package, you would need to use wiring harness # C56225. This harness comes with the relays needed and the wiring required to make everything functional....

  • How to Determine if 2005 Nissan Frontier has Tow Package for Installing Trailer Wiring
    The pin needed to install the # 118263 will be on the frame of the truck, but what matters most is whether or not the rest of the tow package wiring will be present. You would need to remove the passenger side kick panel to the right of where a passengers right foot would be. If there is a harness plugged in there that looks like what's picture then all you would need is the # 118263. If not you would need the part # C56225 instead.

  • Solution for 2006 Nissan Frontier with No Trailer Running Light Circuit Active
    The trailer running light issue you are having with your 2006 Nissan Frontier is pretty common as Nissan for some reason left out the relay needed under the dash panel. Check out the picture I attached to see where you'll find where the relay needs to install. For this relay, you can use one of the blue relays from the Curt Relay Kit # C57000.

  • Wiring Needed To Install a 4-Way and 7-Way on a 2007 Nissan Xterra Without Factory Tow Package
    I hope I am fully understanding that you want to have both a 4-way and 7-way on the back of your 2007 Nissan Xterra. The Curt T-Connector Vehicle Wiring Harness # C56226 is the correct harness to give you a 7-way, but the Replacement Harness # 118263 is for the Tekonsha and will not fit with the Curt already connected. Instead you should get the Curt and replace the end with the Multi-Connector # HM40950 which will plug right in place of the Curt 7-way and you will have both the 7-way...

  • Trailer Running Lights Not Working with 2015 Nissan Xterra
    The one missing running light relay is a common issue on certain Nissan vehicles. It is usually a missing relay in the in-cab fuse panel, the blue relay from the Curt Relay Kit # C57000, but you can check the owner's manual for all fuse and relay locations to verify.

  • Replacement Trailer Left Turn Signal/Brake Light Relay for a 2005 Nissan Pathfinder
    I don't think there are any relays under the seat of a 2005 Nissan Pathfinder but there could be some behind the kick panel on the passenger's side, front. The relay that is missing or blown is likely one of the blue relays from the Curt Relay Kit # C57000. The easiest way to determine if a relay is bad is to use a known good relay in place of a potential bad one. The relays for the tow package turn signals/brake lights are under the hood. If the right turn signal one is working, try putting...

  • Are Relays Needed to Activate Tow Package Wiring in 2012 Suzuki Equator
    If the 4-pole connector you speak of was factory installed, everything should already be functional. If you've just installed a 4-ploe, using a part like # 118263, then the relay kit # C57000 would be needed. The brown relay activates the 12-volt circuit to the trailer connector (which you won't need since you have a 4-pole) and the two blue relays activate the right and left turn signal and brake lamp. Since you mentioned that you got a signal at the trailer connector with the turn signals,...

  • Troubleshooting No Power at Factory Trailer Wiring Plug on 2014 Nissan Frontier
    If you are not getting any power at the factory port where the Curt Wiring Harness # C55441 plugs into, this actually may indicate that your 2014 Nissan Frontier is not equipped with the factory tow package. The existing Curt harness will still plug into the factory port like you see on your vehicle, but without the tow package you will still need to add a relay harness for the port to become active. This relay harness is included with the Curt T-Connector # C56225. It is not available...

  • Relays to Activate 2013 Nissan Frontier Trailer Wiring Tow Package
    If your 2013 Nissan Frontier does have all of the wiring in place but missing the relays you can use relay set # C57000. Check behind the passenger side kick panel for the tow package jumper harness. That harness, if present, is where the relays go. If you are missing that jumper harness you would need either # C56225 for a 4-Way.

  • Troubleshooting 2009 Nissan Frontier4-Pole Trailer Wiring Harness That Wont Operate Trailer Lights
    Most likely, your problem is caused by a blown fuse or relay caused by a short in your trailer wiring. First, make sure that the wiring harness that holds the relays behind the passenger side kick panel is plugged in all the way, until it clicks. Make sure the 2 blue relays are fully seated in the harness. You can see the location of the harness by clicking the provided link for the # C56225 wiring harness. You can also check the point where the # 118263 plugs in under the vehicle, making...

  • 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 Trailer Running Lights Not Functioning on 2013 Nissan Frontier
    It's very possible that the trailer running lights relay on your 2013 Nissan Frontier has gone bad and you'd need to replace it with one of the blue relays from the Curt Relay Kit # C57000. Easiest way to test this is to swap the blue relays around in the harness that's under your dash and see if this causes the circuit to activate again. I attached a picture of where the blue relays are as well. Another easy thing you can check is for corrosion on the trailer wiring pins on your vehicle....

  • 2011 Nissan Pathfinder Troubleshooting Trailer Running Lights not Working
    There is actually two trailer wiring connectors on your 2011 Nissan Pathfinder. One of them controls the 4-way functions and the other controls the 7-way functions. It is possible that you are trying to install the # 118263 into the wrong one. I attached a picture that shows the correct one to use. There is also a relay under the hood of your vehicle in the fuse box that controls the trailer running lights. It should be blue like the # C57000. It is possible that this relay is missing...

    If your Nissan Pathfinder LE does not have a factory 7-Way connector on at the rear of the vehicle then your vehicle was not equipped with the factory tow package. I do not have a picture of the Pathfinder with a factory connector available to send you. To install a brake controller and 7-Way RV plug on your Pathfinder you will need a brake controller like the P2, item # 90885, that your referred to, a 4-Way connector item # 118263, and a Brake Controller 7 & 4 Way Installation Kit, item...

  • How to Determine if a 2009 Nissan Xterra has a Factory Tow Package to Add Trailer Wiring
    The easiest and definitive way to determine if your 2009 Nissan Xterra has a factory tow package is to give the VIN to a dealership and have them determine what options it came with from the factory. Another way would be to use a circuit tester, like # PTW2993 if needed, and test the factory connection point under the vehicle. It should show signals when the brakes are applied, lights are turned on, and turn signals engaged. However, even if it shows signals, it does not necessarily...

  • 2017 Nissan Frontier Trailer Wiring Troubleshooting
    It could be a fuse in the engine bay of your 2017 Nissan Frontier. look at your owner's manual and find the fuses/relays related to the tow package wiring to see if they need to be replaced and or put in. If it's not a fuse/relay, I would test the 4 pole # 118263 coming out of your truck. The open piece on your trucks 4 pole is ground and right next to that is your taillight/side marker lights. Make sure you're getting power when the truck is on using this tester # PTW2993. If so, it's...

  • 2013 Nissan Frontier SL 7-way Wiring Harness Installation Troubleshooting
    The relays that you need to install that came in the Curt T Connector Kit # C56226 would still need to be installed on the wiring harnesses in order to get your lights to work; you may need to go through the firewall on the passenger side of the engine compartment and push those wires into the cabin of the vehicle to make them easier to find from behind the kick plate. Once you locate them and install the relays your lights and power should work. If you're able to get the relays plugged...

  • Troubleshooting 2016 Nissan Frontier Trailer Wiring with No Turn Signals
    Thank you for describing the trailer lighting issue you're having and the testing/troubleshooting steps you've taken to diagnose the cause. If I understand correctly you have a 4-pole harness such as # HM43575 which does indeed plug in to the OEM tow package wiring under the vehicle. For reference I linked a photo of this item's OEM plug which should match what is on the Frontier. Since you have tested the contacts on the vehicle plug where this item connects (with a tester like # PTW2992)...

    Sounds like you have been troubleshooting the wiring and have found that the problem is somewhere on the 2005 Nissan Frontier side. You said the right turn pin is not showing current when you check it out. The next place to check would be on the wire that is going into the connector. If you have no power going to the connector the problem lies upstream. If you find that the connector is bad, I recommend replacing the OEM harness with part # 118267. This harness is designed to plug into...

  • No Power To 7-Way Vehicle Connector on 2008 Nissan Pathfinder After Tow Wiring Harness Installation
    On your 2008 Nissan Pathfinder the Towing Relay 2 fuse is the brown relay, like the one included in kit # C57000.This relay will activate the 12-volt power circuit on the 7-Way connector. This relay is located in a fuse box under the hood, next to the vehicles battery. Next to the brown relay will be Towing Relay 1 (blue) which should be installed to activate the running lights and signal for the 4-pin towing harness. To charge a trailer battery from the 7-Way you should be using the...

  • No Running Lights on Trailer Towed by 2007 Nissan Frontier
    On some Nissan vehicles there is an additional relay needed in the in-cab fuse panel to make it fully functional. Consult the vehicle owners manual to find the locations of all fuses and relays associated with tow package wiring. It is also possible that, even if all the relays and fuses are in place, that one of them is bad and will need to be replaced. If there is a missing relay then it can be replaced with a blue relay from # C57000. If it is the lights on the trailer that are not...

  • 2005 Nissan Xterra Trailer Wiring Troubleshoot
    According to Curt, if your Xterra does not have the full tow package installed, the # 118263 will install, but as you have found, the trailer tail lights will not function. It sounds as if your Xterra does not have the factory tow package. For the Xterra without the tow package, we recommend either the Curt # C56225 which includes the sub harness and relays (which unfortunately, are not sold separately) or the Hopkins # 43605 that taps inline with the factory harness connection to the...

  • 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.

  • 7-Way Trailer Wiring Harness Recommendation for 2011 Nissan Frontier with 4-Way
    Good news! You can just switch in the 7-way harness # 118267. The relays included in the 4-way kit # C56225 will be the same.
