Video Transcript for Tow Ready Custom Fit Vehicle Wiring 118263 Review

Today we're going to be taking a look at the replacement OEM tote package wiring harness with the 4-way flat connector. This product is going to fit the following vehicles: 2005 through 2012 Nissan Frontier Pickup, '05-'12 Nissan Pathfinder, '05-'12 Nissan Extera, and '09-2012 Suzuki Equator. This is an exact replacement for the damaged OEM wiring harness. It's going to provide your 4-way flat connector at the back of your vehicle to power your trailer's signal lights. It does come with a dust cap, it's already tethered to the housing so you don't have to worry about misplacing that or losing that. That's going to do a great job at covering up the connection points when your plug's not being used.

This system is going to connect quickly and easily. It's going to come with your detailed installation instructions to walk you through that whole process step-by-step. Basically, all you have to do is locate the connection point depending on your vehicle, take the gray connector, and plug it into the OEM connector on your vehicle. The plugs are going to match up perfectly, they're going to snap lock together for a nice, tight, secure fit. Once you have that done, you can use the included cable ties to secure any access or slack in your wiring, and then you'd wrap this towards the rear of your vehicle. That way it's easily accessible to make your connections to your trailer.

We do recommend using some dialectic grease on all of your electrical connections, like the plugs on the vehicle and the 4 port connector itself. That grease is going to do a great job at preventing rusting and corrosion at connection points. If you need some of that, it is sold separately and you can find it right here at That's going to do it for today's look at the replacement OEM tote package wiring harness with the 4-way flat connector.

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.


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


way too easy.


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


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.

-- comment by: BYRON Z - 12/04/2012


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 relay as part # 38666-1
Relay - Blue - 4 Terminal - 12 Volt (Qty 1)
. 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.
-- Etrailer Expert Mike L - 10/24/2018


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.
Gary - 12/12/2021


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.


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.


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.


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


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


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.


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




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.


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.


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


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


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.


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.


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


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.


Part was just what I needed and price was fantastic.


Easy to install. Custom fit. I would first check in with etrailer for all future needs.

  • 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.

  • 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 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...

  • 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.

  • 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 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.

  • 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 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 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...

  • 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...

  • Running Lights Stopped Working on a Trailer Towed by a 2005 Nissan Pathfinder with Tow Package
    It sounds like you may have a ground problem either on the trailer, on the Pathfinder, or both. A ground problem can cause the lights not to work properly. It can appear suddenly or gradually, and appears usually when the system is under load (running lights are on). First, make sure that the trailer side and vehicle side connectors are free of dirt and corrosion inside and in the backs of the plugs. You can then use a a circuit tester like # 40376 if needed to make sure the 7-Way has...

    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 # 118525 instead.
