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..

Average Customer Rating:  4.9 out of 5 stars   (78 Customer Reviews)

Replaces a damaged harness and 4-way plug for your Tow Ready Nissan vehicle wiring harness (118525). Does not include the relays needed to activate your Nissan's tow package.

by:

I loved, great store outstanding service , very fast service great information on instructions video , I will recommend to anyone about the products that i both excellent , I will definetly do business with E-trailer again , thank you so much



by:

The part that I purchased is good. The harness fits and seem to be very good quality. My Exterra had the connector in the back to plug into. I thought that this harness was all I needed to make a connection to a trailer. After connecting the harness I only had turn and break lights. I did not have running lights. I needed to purchase a receiver hitch tow harness kit from nissan (part # 999T8-N5005). This kit includes the relays that are needed to safely run the running lights on this car. Wiring into the running lights as a shortcut can cause damage to the computer.

CAN U RUN THE PLUG WITH OUT [RUNNING LIGHTS ].OR WILL IT DAMAGE THE SYSTEM. AND WHAT WAS THE COST OF THE RELAY KIT FROM NISSAN $$

Etrailer Expert

Patrick B.

12/5/2012

If all you are missing is the running light function, you will need one additional relay to activate the running lights. You can find one at an auto parts store.


by:

I received my Hidden Hitch and OEM wiring harness for a 2012 Nissan Frontier faster than expected as I took advantage of the free shipping. The hitch bolted right in place with no difficulties and the wiring harness fit correctly. I haven't had a chance to use either as yet but I'm confident everything will work as expected. When I purchased my new truck it was the truck salesman who recommended etrailer to me and I am glad he did.



by:

Quality product, quick and easy install on my 2010 Nissan Xterra. Only part that gave me some trouble was getting the factory cap off of the Pre wired plugin. Once the cap is removed, the wire harness plugs right in and you zip tie it in a few spots and your done.



by:

Having trouble making it work with the vehicle. Marker lights aren't working, but the lights on my car are.

From what you describe, it sounds like your Xterra is missing a relay that activates the running light circuit in your tow package wiring. We offer the relays as part # C57000. The fuse block that the relay plugs into is typically located to the left of the steering column, on the underside of the dash. The lower portion of the dash should be removable or should be hinged so it can be lowered to access the fuse block.



by:

Looks like it would work great but was for a friend and he hasn't put it on his car yet. :)




by:

Great product. It took me maybe 5 minutes to plug the wire harness into the factory connector, now it's trailer ready.



by:

Had a little problem taking the plug cover off the factory installed wiring harness on my Nissan. But once I figured it out, the new harness snapped in beautifully. I used a couple additional ties to keep the wiring harness tight to the frame. Good purchase.



by:

Shipping was incredibly FAST. I installed it myself. This harness is great. Just plug it in and back up to the trailer and GO. Easy enough that I could do it with 0 (ZERO!) electrical skills.



by:

Plug fits, correct length. I wish Nissan ran running lights to their 4 pin connector without needing extra parts or tapping another wire though.



by:

Wiring harness and Hidden Hitch both fit perfect and was easy to install on my Nissan Frontier.



by:

Fit right on the existing wiring harness. Although I have not hooked a trailer up to test it yet.



by:

I like the price and the part was exactly what I needed. Then I was informed of everything going on from shipping to arrival. Thank you for the great service, you guys really know how to treat your customers well. I recommend you to anyone I know looking for parts.



by:

Excellent packing and timely arrival. Your hitch is built like a tank and obviously meant to last. Installation was a breeze as everything fit like it was supposed to.

I would definitely reccomend your product.



by:

Customer service was very friendly and helpful (did a fantastic job). Your customer service rep is the primary reason I will do business with etrailer in the future. I received the part ahead of time. The part was the correct part and was easy to install. I will definitely order from etrailer again.



by:

Should have read a bit closer, purchased and found out after the fact that I need an additional connector with relays. Information was
supplied on website, I just overlooked.



by:

The product arrived on time as advertised. I have used etrailer numerious times with complete satisfaction.



by:

I wanted you to know that I found dealing with E Trailer was
a great experience no hassle, fast, your operator was great
the product fit and was easy to install great price. I would recommend to friends and already have.



by:

Part was just what I needed and price was fantastic.



by:

Would order parts from etrailer with no hesitation. Had what I needed for a reasonable price. Thanks again.



by:

VERY EASY TO INSTALL JUST A SIMPLE UNPLUG OF FACTORY CAP AND PULUG IN THE HARNESS DOESNT GET ANY EASIER TO INSTALL THAN THIS HARNESS. AND A GOOD PRICE FOR THIS HARNESS. VERY HAPPY.



by:

Arrived on time and worked perfect. I would recommend etrailer for any related needs.



by:

Easy to install, looks like factory, very happy. Thanks

Excellent after 1 year it still looks and performs like new. Couldn’t be any happier with this product.

  • Replacement OEM 4-way Harness for a 2011 Nissan Frontier Recommendation
    If the window sticker of the 2011 Nissan Frontier that you are looking at says that it has the factory trailer wiring you should already have the Replacement OEM Tow Package Wiring Harness, part # 118263, that you referenced. This product is for people who have either damaged their OEM harness or had a Nissan that did not have the wiring from the factory. The truck you are looking at should already have a factory 4-way if its says it is pre-wired and you should not need this product.

  • Trailer Brakes Lock Up with a 2011 Nissan Xterra
    The issue you described is a very common problem on 2005-2013 Nissan Xterras. The manufacturer had switched the blue brake output wire and black 12 volt wire which then caused the brakes to lock up when the trailer connector was plugged in. The good news is that it is an easy fix which entails just switching the wires back around which can be seen in the attached help article. The above issues is however not really going to cause the trailer lights to not work. Therefore, your first step...

  • 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.

  • Troubleshooting Prodigy P3 Brake Controller that Stopped Working
    The most common cause for a brake controller to stop functioning is corrosion on the pin of the 7-way that carries the voltage to the trailer brakes. All you have to do to fix that is to take some sandpaper to the pins of the 7-way and you'd take care of that. What does the P3 controller show on the display when connected to a trailer though? That will be a good indicator of where the problem is most likely located. I attached an article on troubleshooting brake controller installs for...

  • Troubleshooting 2015 Nissan Xterra that Lost Trailer Stop and Turn Signals
    Sounds like there are some blown trailer wiring fuses/relays under the hood of your 2015 Nissan Xterra that are in need of replacing. Check all of the fuse boxes under the hood of your vehicle for the trailer wiring circuits and replace as needed. There may have been a short on your trailer's wiring that caused the short as well so be sure to check the wiring of the trailer for the short before you reconnect the trailer to your Xterra.

  • Troubleshooting No Left Turn/Brake Signal On Trailer
    The 9:00 position of your 7-way should have the left turn/brake signal and the 3:00 position should have the right turn/brake signal when a 7-way is wired up in the traditional layout. I attached a picture that shows how a 7-way typically get wired. It sounds like your 7-way is functioning correctly if the 9:00 pin has voltage with the left blinker on. Is it possible the problem is on your trailer wiring? A bad ground could easily cause the problem you described. Check the grounds of the...

  • Troubleshooting Taillights Not Illuminating on a Trailer Towed by a 2009 Nissan Frontier
    It sounds like there is a short on the trailer and that is what caused the lights to stop working after a brief amount of time. If you plan on towing with this trailer again I would recommend you go over the wiring of the trailer looking for an obvious shorts in the circuitry and fix as necessary. I did some research out on the internet and read one post where a guy had your exact problem and he unplugged all of the trailer relays and harnesses and then plugged them back in and started...

  • Not Getting Power to the Factory Trailer Wiring on a 2007 Chevy Silverado
    If you test the trailer connector on your 2007 Chevy Silverado and it is not providing power when the lights are on, that would indicate there is a problem in the tow package wiring and you will need to trace the wiring towards the front of the vehicle to see if there are breaks anywhere. If the problem is occurring on the trailer side, the problem could be a dirty or corroded trailer connector or a bad ground on the trailer at the connector or the lights. Grounds should be attached to...

  • Troubleshooting Why Trailer Lights No Longer Work
    It does sound like you have a blown fuse or bad relay in your vehicle. You can find the fuse panel legend in your owner's manual or ask your dealership where the trailer towing fuse is located. There may be separate fuses used for trailer lighting. If the fuses and relays check out okay you will want to check the vehicle and the trailer connectors and wiring to make sure they have not been damaged or possibly had the ground wire come loose.

  • Troubleshooting No Trailer Running Lights on a 2007 Nissan Frontier
    Most likely you did blow a fuse or relay under the hood of your 2007 Nissan Frontier. You will need to check your fuse box legend to determine where the running light trailer wiring fuse is and replace it.

  • Installing T-1 Harness, Part # 118263 on 2005 Xterra Without Tow Package
    In order to use the T-1 Harness, part # 118263 on an Xterra without the factory tow package, in addition to the relay, you will also need the jumper harness. The harness is a dealer supplied part. Once you purchase the T-1, the relay, and the jumper harness you will have spent quite a few dollars, when you could purchase the Hopkins Custom Fit Vehicle Wiring Harness part # 43605. You would spend a bit more time installing it, but it would probably be less expensive.

  • 4-Way Trailer Connector for a 2015 Nissan Pathfinder
    Wiring harness # 118263 is only part of what you would need for your 2015 Nissan Pathfinder. There is also a jumper harness and relays that will be needed to make the harness fully functional and is not included with # 118263 since it is for models that have the factory tow pacakge. To get everything needed I recommend # 118670. It comes with the jumper harness, relays, and the 4-Way harness.

  • Plug-N-Tow Vehicle Wiring Harness Vehicle Connection Location on a 2008 Nissan Xterra
    Wiring harness # 43605 plugs in behind the taillights, with an additional wire run to front of the vehicle to connect to the battery. You can refer to your owner's manual for information on how to access behind the taillights, (search under how to change bulb). If your vehicle has the factory towing package, you need wiring harness 118263, the connection point on this harness runs along the frame on the driver's side.

  • Is a Module Needed To Safely Install Trailer Lighting on a 2007 Nissan Xterra
    Your local mechanic is more than likely correct. Newer vehicles have sensitive components and thinner wires than ever before and adding trailer wiring that is powered by the vehicle wiring can overload the wires or sensitive circuitry and cause any number of problems. The solution to your dilemma is a Modulite powered wiring harness. This type of harness is designed so that it uses the signal from the vehicle wiring to activate the trailer wiring functions, but the power is provided for...

  • Which 4-Way Wiring Harness for 2005 Nissan Xterra SE Wiring
    To find the correct wiring harness for your 2005 Nissan Xterra, you would need to know whether or not the vehicle has a tow package installed. To find this out for certain, you could check your paperwork for the vehicle or call the dealer with your VIN. If you do NOT have the tow package either part # 43605 or 118263 could be used, but in order to use # 118623 in the Xterra without the tow package, a relay that would be obtained from your Nissan dealer would need to be installed. If you...

  • 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...

  • Which Trailer Wiring Harness Fits a 2008 Nissan Xterra Without Tow Package
    Because your vehicle did not come with a tow package, you will need the Plug-N-Tow Vehicle Wiring Harness # 43605. This will plug right in for you and give you that 4-pole hookup. This harness is a powered converter which draws power directly from the vehicle battery instead of through the wiring system. Connection points are located behind the vehicle tail lights. An additional wire will need to be run to the front of the vehicle to connect to the positive post of the battery.

  • Does the Trailer Wiring Harness # 56087 Require the Factory Tow Package on a 2011 Suzuki Equator
    The CURT Custom Fit Trailer Wiring Harness, item # 56087, does not require the factory tow package for installation. This harness plugs inline with the existing tail light wiring harness on the vehicle. I have provided a link to instructions for you to review. If your vehicle does have the factory tow package wiring, then you could use the Replacement OEM Tow Package Wiring Harness, item # 118263, on your vehicle. I have linked instructions for this harness also.

    The Plug-N-Tow (TM) Wiring Harness, item # 33525, will plug in between the male and female end of one of the sets of connectors that you are seeing. Once you separate the connectors it will be obvious whether you have the correct one or not. You are looking in the right area, behind the drivers side bumper on the frame rail. If your vehicle has the factory tow package then you would need the T-One Vehicle Wiring Harness, item # 118263, to make the connection at the rear of your vehicle....

  • 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...

  • 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.

    The 12 volt accessory circuit that you have on the 7-way of your 2000 Dodge Ram 2500 can put a maintenance charge on a trailer battery while you are driving, but it wouldn't have the amperage to charge a dead battery. To be able to fully charge the trailer battery from a discharged state you would have to use the CTEK Multi US 7002 12-Volt Universal Battery Charger, part # CTEK56353. This charger can be used to fully charge the battery and then you can maintain that charge with the vehicles...

  • Troubleshooting Trailer Turn Signals Not Working on Wiring Harness for a Nissan
    This does sound like a bad or missing relay. You can test the 7-Way connector without the trailer attached to see if you get any signal at all on the turn signal/brake light circuit. If you do get a signal but the lights are not working on the trailer, it could be that the extra load from the trailer lights is not allowing them to function properly. This would indicate that most likely the grounds of the trailer light assemblies are not sufficient. You will want to make sure the assemblies...
