Perfect ! First time I install a hitch and this kind of electric Harness. I was a little confuse on what to do first but well explain and it went very well. Tips : On my Tesla model 3 2020 there was a 12v plug already coming directly from the 12v battery in front, so it was a lot easier then passing this cable my self. The cable is in the bumper, you should see it if you install the hitch :-) I own a company and I work with computer, so nothing to do with mechanics and electronics. Just study the plan, watch videos online. Once you understand exactly how it works, it's pretty easy to install.

The product works great. The worst thing about it was that there were no instructions with it at all. I had to email etrailer and they in turn emailed me the instructions. Other that that no problems. Fast shipping and product is as advertised. I used this product on my Victory Vision so that I could pull my trailer. Below is a picture of where I placed it. It worked out best in my opinion to velcro it to the back of the saddle bag. It actually mounted right under the wiring harness of the bike that I had to tie into.

Still works great. No problems at all.

A module such as this is absolutely essential when trying to add a trailer lighting circuit to a modern CANbus equipped vehicle. The module itself works beautifully but I deviated from the eTrailer install video for my '13 Jetta Wagon. First, I used the 'poke-n-wrap' method with solder to attach the module's signaling wires to the vehicle wiring harness. I have a personal aversion to Scotchlok or vamp connections because they often fail with time and vibration. This method keeps the harness relatively compact and clean looking, especially if you resecure everything with cloth wiring harness tape. Second, no self drilling screws. I attached the module to the chassis with proper self adhesive tape like 3M VHB. The white ground wire is easily attached to the existing grounding lug on the left rear wheel well, so no self drilling screw there either. Don't poke holes in your chassis with self drilling screws if you can avoid it. I avoided drilling a hole in the spare tire well by running the power wire through the existing body plug in the area aft of the right rear wheel well. It's easy to remove the plug, drill a hole in it, and thread the wire through. Add a dab of black RTV to make sure it's watertight. When powering the module, the suggested method is to split the 1/4" ring terminal and stuff it under the nut that holds the positive battery terminal in place. Instead, I obtained an M6x1.25 nut and secured the fuse holder to a unused, unfused stud on the terminal block inside the underhood fuse block. When it's time to change the car's battery, the split ring will inevitably get deformed and may cause problems. This way, the positive terminal clamp only has to do one thing: hold onto the positive terminal. To bring the wiring harness outside the wagon I went a little off the deep end with a little sheet metal work and Molex MX150 connectors to make the passthrough watertight. I added etrailer 18140 and 18144 to mount the 4-way connector to the hitch so I wouldn't have to fish the wire out of the left-side trunk compartment and shut the tailgate on it every time I wanted to tow.

thanks for being so helpful in switching us into this heavy duty wiring harness. The service was better than all face to face places in this type of business. My installer swapped out the modules and everything worked perfectly. I can't say enough about both customer service and the tech support that we received. There should really be a sixth star (for above and beyond)!

Install on 2018 Mercedes Benz CLA250 w/LED tail lights: There were no guides I could find so I'm posting this for other etrailer customers. These are my installation notes and the kit operates correctly. There are other ways to do this, I'm sure. It isn't necessary to remove the tail lights, there is a removable piece in the trunk carpet. I removed that and the plastic trim panel in the middle. The tail lights have 10-pin connectors. On the left there are 8 wires on the right there are 7. My thought is maybe this has something to do with the european style parking lights. After probing I found this: Left Side: Turn/Brake - Yellow with White stripe Running/headlights - Black with Orange stripe There is constant power to the Green with White stripe Right Side: Turn/Brake - Light Blue with Red There is constant power to the Green with White stripe I had to splice additional wire to mount the module where I wanted it. The final connections were: Module Brown to Left Black/Orange Module Yellow to Left Yellow/White Module Green to Right Light Blue/Red Module White to Ground Module Black to Battery Module Red Terminated (unused) The positive electrical connection I made was under the hood, off the fuse box. Terminated to one of the lugs, covered with wire loom, and run into one of the cars wire bunches. The 4-wire hitch output is terminated with a CURT tester (If you put one there, you'll always know where it is when you need to troubleshoot something) This vehicle is completely covered on the bottom and running the wire can be very time consuming if you want it to look tidy.

This kit was great and functions exactly as intended. With the help of the online video it was easy to install, even for people without any electrical knowledge. My only advice is: 1) watch the video and the hitch installation video at the same time. This will help you plan ahead and not re-install parts during the hitch installation, that will need to be removed for the harness installation 2) be VERY careful about selecting the right wires, by using the testing tool eTrailer provides. In the install video for my BMW X5, the technician referenced a yellow and black wire when making the initial connection. He later goes on to make a separate connection for a black and yellow wire. To the novice they look nearly identical. I confused the two wires and had to re-do this, but would not have been an issue if I had understood the distinction and used the testing tool, as recommended in the instructions 3) be careful about placing all connectors so that they face in the same direction. Does not impact function, but makes for a neater install when complete. I could not be happier about how this project turned out, and credit etrailer with all of the success. It has a very OEM look, and etrailer made the entire project doable for me through their great suite of videos and excellent Customer service. I wish every retailer could be this good!

I followed the installation steps that were on a Youtube video from your company and it was a snap! Everything that I needed for the install was included in the kit, except for one butt connector, but I had plenty of those and it all went smoothly. I don't have the trailer yet so I can't verify that the connections were correct, so I'll follow up in a week or two.

The harness works perfectly with my 2015 Honda Fit and installation was pretty solid, especially now since Honda makes interior clips easy to remove. I had trouble with the wiring at first due to having the 3 wire system, but after giving etrailer a call during the install I was walked through which colors go where (I was watching the 2014 VW Passat video where they say to make the red wire the extra ground, don't do it with the Fit! It's the brake light FYI). No instructions included, just check out the sample videos on this page for the install on other similar vehicles. We purchased the custom Drawtite hitch and wiring harness to help pull along our hot dog stand (Gnar Dog's Hot Dog Stand) in the greater Cincinnati Area. Couldn't be in business without etrailer; thanks guys!

I installed my unit on a 2013 Audi a4 quattro sedan. using the provided tester I determined it is a two wire system. i installed unit in driver side outside of trunk. I easily snaked the green wire through trunk to passenger side chamber. The battery is in the trunk, so it was easy to connect supplied fuse connector directly to battery. Wiring: Unit green wire to gray/blue wire on passenger side Unit Yellow wire to gray/white wire on drivers side Unit Brown to Green wire on drivers side. No drilling needed Ran trailer wire into trunk and out through cut out on trim where hitch is Works perfectly. Reason for not a 5: No directions and missing 1 crimp connector.

Overall Kit is good. Some of the wires on the kit need to be longer by about 12 inches as it results in having adequate length to trim. Also the kit should include butt splice connectors instead of the blue crimp (no strip connectors). These type do not work as the OEM wire is to small to work effectively with this style of connector. The power connector eyelets are too big for the battery terminals. Overall good kit. Make the changes and this would be an excellent kit.


Comments
This is not a vehicle-specific kit that will work right out of the box with most vehicles. However as you found, there will be a little necessary modification on some vehicles.

Installation was VERY SIMPLE and straightfoward, especially sinse the installation video etrailer provided was on a 2002 e53 x5 and thats what I imstalled my harness on. Everything works great and I will most definitely be buying through etrailer again. Shipping was fast also!

The hitch works fine and installation was straightforward. I wasn't to keen to slice into the car taillight wiring, but was preferable to paying the dealer hundreds for their module. You should inform customers your trailer light module draws power from the battery and they should pull the fuse when the hitch is not in use to avoid draining the car battery.

I installed this 119190KIT into my 2015 Toyota Prius Plug-In Hybrid. I could find no review that addressed installing into a Plug-in Prius Hybrid. There were several reviews of various years of standard (non-Plug-In) Praises, but no reviews for a Plug-In. The eTrailer webpage video for 119190KIT (https://www.etrailer.com/Custom-Fit-Vehicle-Wiring/Tow-Ready/119190KIT.html) has links to 4 other videos, none of which is for a Plug-In Prius (PIP), but one or more of them shows how to test and splice wires just like in the 119190kit. The video for the 2013 BMW X3 shows how to use the tester at the 2:48 mark. This tester was essential. I used it to determine which lights were connected to which wires. Do NOT rely on any videos to determine which color wire connects to which light (tail, brake, left turn, right turn). Instead, follow EXACTLY what the instructions sheet tells you. The first step was to determine which color wires in my PIP connected to which lights in the PIP’s rear tail area. When you use the tester, you MUST push the metal pointed tip directly and forcefully into the center of the plastic sheet encasing the wire. If you do not penetrate fully, you won’t get the tester’s light to come on when you press the car’s brake pedal or light switch or turn signal lever. A video that shows the internal compartments for a Prius is at this link: https://www.etrailer.com/tv-install-trailer-wiring-2010-toyota-prius-118505.aspx It's not a Plug-In model, but it shows a lot of spots that are identical nonetheless. I found that there was not a lot of slack in the wires in the PIP’s taillight assembly, but there was enough. The video below shows a 2010 Prius and how to remove the rubber seal - at about time stamp 0:30+. A good spot to screw the ground into the "doubled sheet metal" is at 2:03+. A good segment to show putting the wires under the back side of the hatch starts at about 3:00 and runs until about 3:22+ and also at 3:30 it shows how/where the banded 4-pole wire will go into a lower compartment, to be stored until need to attach to a trailer. 3:53 - 4:41 shows running wire over to the other taillight. From 5:10 to 6:20, it shows hooking up to the battery. https://www.etrailer.com/tv-install-trailer-wiring-2010-toyota-prius-c56147.aspx This video shows a 2014 Prius V.... https://www.etrailer.com/tv-install-trailer-wiring-2014-toyota-prius-v-118610.aspx It shows the actual part that I have to connect - 118151 which includes the yellow "circle" wire.  Go to time 5:00.  It shows the yellow loop (aka, fuseholder) in the kit and how to install it at around time 5:42+ thru 6:23 and beyond shows attaching the yellow to the positve battery pole at around 6:40 to 7:00.  Shows adding fuse to fuseholder at 7:13+. At 7:30, starts to show attaching the ground wire to the "factory ground.  Through and past 9:20 shows zip-tying all wires. Here's another video that shows splicing…..with the kit’s “no-splice” connector. https://www.etrailer.com/tv-install-trailer-wiring-2013-toyota-prius-119147kit.aspx ....at 3:30 to  about 5:13. WARNING - you must use pliers as shown to connect two wires that the directions say to connect. You have to squeeze the pliers pretty hard to get the metal piece in the plastic quick-splice connector to go all the way through the plastic sheathing and then make contact with. The video does not emphasize that you have to squeeze the metal piece pretty hard. In fact, when I first used four quick-splicers for connecting and then tested to see if a connection was made, only one of the 4 quick-splice connectors resulted in an electrical connection. So, I had to open up the 3 connectors and press the metal piece inside the quick-splice connector real hard. So, be careful!! I have a moderate degree of experience with home electrical wiring, but none with car wiring. I just took my time and it all worked great!!!

I was very satisfied with this purchase and it is still going strong. I save my 5-star reviews for the most amazing products, and this wasn't quite there. Everything went together as advertised, and it has worked every time I used it (5 or 6 U-haul rentals). My only minor disappointment was that there wasn't a better way to run the wire from the controller to the engine compartment. That could be as much about the car as the kit. I would definitely buy it again or recommend it to a friend

I purchased this harness for my 2014 BMW X1 along with a Draw-tite Trailer Hitch. I paid the local BMW dealer to install them both. For the first trip the electrical connections worked perfectly. On our second long trip, we noticed that the left lights on our trailer were constantly 'ON' and the left turn signal did not work. When we turn the vehicle entirely off, the left taillights are still on as they appear to be drawing power. Has the 'module' gone bad on its second trip?


Comments
Thank you for your review. It does sound like you have a common ground issue. I recommend to make sure the ground wire is attached to a bare metal surface of the vehicle. Please let me know if that fixes the issue.

Easy to install on a 2014 X5D M sport with LED lighting package. For others attempting the install, here's the wiring that I used: Module X5 Yellow -> Right side (black/white) Brown -> Right side (purple) Red -> GROUND (same screw as the white wire) Green -> Left side (black/purple) White -> GROUND Took about an hour to install, the X5 has a great ground screw and place to store the module on the drivers side. Test light included helped make it easy to find the right wires (but, now that you have the above map, you won't need to find them if your truck is like mine). Great service from eTrailer, delivered quickly with all the parts. My only complaint is that this module doesn't look that good hanging out the back of the X5 when trailering, I knew that going in, and given the outrageous cost of the stock trailer system (1000+), this was a good compromise for me and anyone who doesn't trailer all that often.

I would have rated this better if good installation instructions were provided for my car model. If you're going to connect the 119190/119191 kit to a 2012 VW Golf, like mine, you will find that the correct wiring is from the ModuLite catalog Vehicle Code BM-1 3-Wire System (such as Mercedes R-class) - NOT the B 3-Wire System as listed in the ModuLite catalog. My VW Golf uses the same bulbs for taillights (providing 6 volts) and brake lights (providing 12volts). To make the converter work correctly, ground the brown "tail light" wire and connect the red "stop" wire to the VW wire that lights the tail light. In the three pin taillight connector (right or left side of the car) the middle wire is a ground, one outside wire is the turn signal and the opposite outside wire is the tail/brake light. Connect the red wire to the wire that is NOT the turn signal. If you follow the ModuLite B 3-wire suggestion and connect the red wire to ground and the brown wire to the VW tail light wire, the turn signals and brake lights seem to work correctly during the day (when you don't have the taillights on) but when you turn on the taillights, you don't get brake lights when you apply the brakes.

I bought the 119190KIT, TK90160, and ETBC7 based on etrailer's recommendations for my 2010 VW Golf. I came into DIY trailer electronics without a clear understanding of what I needed, so I asked etrailer what would work for my car, and they put together this well-priced and high quality bundle for me. The parts arrived quickly and in good order, and using the included instructions and some videos from this site, the installation process was fairly painless. The biggest hitch for me was that the VW MKVI runs multiple modulated signals along one wire to the tail lights, so wiring for the turn signals had to be run up to the headlights instead. The kits didn't include this information, nor enough wiring to do that extra work, but it didn't set me back very much more. Great service, great products, and lots of excellent information on this site. I'll definitely be an etrailer customer for any more trailer stuff!

The kit came complete with all that was needed for installation and really fast shipping. The video offered on the etrailer.com website for the BMW E70 X5 was outstanding and provided all the detailed instructions needed. I had absolutely no problems and the job took about 1 hour. The system worked flawlessly when connected to my Road King trailer. Coupled with the Curt Class III hitch this combination made for a much less intrusive trailer hitch option for significantly less than the OEM option. I would highly recommend this trailer hitch kit.

Outstanding. No problems at all. It was a cinch to install. Have towed utility trailers and boat trailers without issue. Much less expensive and a lot cleaner installation that factory.

The trailer lighting kit I purchased from ETrailer was an easy installation and works as advertised. There were only two things that could have been better. The kit was missing one butt connector and the green wire was a bit too short for my installation on a 2013 VW Tiguan, so I had to extend it. Although I have many DMMs and other test gear, I found the included tester to be my choice of testers for this installation. It does the job well and is easy to use. Just remember to cup your hand over it if you are working in direct sunlight or you may not see it turn on. The only recommendation I have for the manufacturer is that a list of vehicles be included in the installation instructions so that the proper wiring setup is easier to identify. It wasn't too hard to figure out, but I would have felt a lot better knowing I made the correct choice before I started making permanent connections. It helps to use a set of ramps on the left (driver's side) front and rear wheels to have enough room under the vehicle to run the long power lead. Installation did take a few hours, but I didn't rush the job and I also was talking to a neighbor as I did the work. Watching the installation video was very helpful. I picked up quite a few tips and knew exactly what to expect. If you have a Tiguan, use the VW-supplied tool to help remove the rear lights. The tool helps to pull a cover off of each light to gain access to the bolts holding the lamp assembly in place. Once you have the bolts out, pull the light assembly straight back while wiggling it to free it from the white retainer. To remove the electrical connector, turn the lamp assembly upside down and pull out the red part until it stops. Next, depress the clip just in front of the red sliding piece to remove the power connector from the lamp assembly. Sorry, I should have taken photos. In summary, I highly recommend this lighting kit if you have LED taillights. It was easy to install and it works great!

I have a 2014 Tiguan and am considering this wiring option vs. the expensive stock set up. I am wondering if you get any check lights on the dash when using this set up with a trailer? Thanks!

Excellent quantity. Directions great for hitch which included my variation on hybrid RX450h. The Electrical harness kit directions could have been better, they were pretty generic and where not specific for my RX450h. However they were good generic directions, just feel they should be more model specific. I didn’t need the approximately 10 feet of wire for battery hot wire since the hybrid battery is in the rear. Prefer a harness that is a plug and play type with no splicing connections. However, the kit did include more than what I needed, even a test light prob which I have in my tool box. A person using this kit needs a good automotive technical skill level. Kit directions if specific could even describe required panel removal on vehicle. BI had to figure that out which can be tricky. Especially when OEMs have such a array of fastener types and locations for wires underneath interior panels. All in all, good quality products from etrailer would definitely order again from e-trailer. Wish I took pictures but too late, everything is installed and reassembled.


Comments
Unfortunately, this is not a vehicle specific item that could fit hundreds of different vehicles. Because of this, it wouldnt be feasible for the manufacturer to provide specific instructions for every vehicle this harness could be used on.

    The most affordable route is to install Draw-Tite Max-Frame Trailer Hitch Receiver - Custom Fit - Class III - 2" # 76183 for your hitch receiver then for a trailer wiring kit you can use ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT. For a ball mount to slide into the receiver that will allow fitment to your trailer, I recommend looking into Curt Fusion Ball Mount for 2" Hitches 1-7/8" Ball # C45151 if your trailer coupler...

  • Trailer Wiring Recommendation for a 2013 BMW X3
    Tow Ready has confirmed the part # 119190KIT as a fit for your 2013 BMW X3 so it would fit and work. But for an easier install you might like the ZCI kit part # 119250KIT. This system uses sensors to detect voltage in the wiring of your vehicle instead of having to tap into the wiring like the # 119190KIT does so there would be no splicing. You would also need the # 118151 as well to power the system. If I had your vehicle this would be the system I would use since it will be so much...

  • Recommended Trailer Wiring Harness For 2013 Mercedes-Benz GLK250
    We have a couple of different style wiring kits for your 2013 GLK250, but the # C56190 is not compatible with your car. Most of the harnesses we offer are a hardwire like part # 119190KIT. This kit comes with a circuit tester that helps you identify the wires you need to splice into for the trailer harness. I have attached a link to an installation video you can check out. Another harness we offer requires less hardwiring. It is the ZCI Circuit Protected Vehicle Wiring Harness, part...

  • Trailer Wiring Recommendation for a 2015 Subaru Impreza
    At this time the only trailer wiring harness I can recommend for a 2015 Subaru Impreza hatchback is a universal kit like the part # 119190KIT that will hardwire to the vehicle. The part # C56111 is for older model Imprezas so I cannot recommend it for you. The Curt Hitch part # 11286 that you referenced has also been confirmed as a fit for your vehicle.

  • Recommended Wiring Harness Compatible with 2008 Toyota Land Cruiser
    There isn't a custom fit for your 2008 Toyota Land Cruiser. I reached out to my contact and Tekonsha and we recommend the Upgraded Heavy Duty ModuLite Circuit Protected Vehicle Wiring Harness with Install Kit # 119190KIT. This will be a hardwired system that will easily connect using the quick splice connectors and will also protect your vehicle from electrical overload. He said there was no custom harness before they stopped looking at this vehicle in 2007. Now with a Modulite, they...

  • Installing Tekonsha Vehicle Wiring Kit # 119190KIT on 2014 Audi Q7 with Factory Trailer Wiring
    When installing the Tekonsha Vehicle Wiring Kit # 119190KIT on your 2014 Audi Q7 the harness wires will need to attach directly to the appropriate circuit wires on the vehicle using the included quick splice connectors (as you mentioned seeing in the install video). You won't be able to attach or connect to the plug itself that you referenced. You did reference in your question though that your Audi is equipped with trailer pre-wiring. If this is the case then there should be a round...

  • Installing the Tekonsha # 119190KIT Wiring Harness on a 2017 Mercedes-Benz GLC 300 4WD
    The tail light wiring on your 2017 Mercedes GLC 300 4WD is separate which means that it is a 3-wire system with the brake and turn signals being sent on different wires. For trailers they have the brake and turn signals run on the same wire. To properly install the Tekonsha # 119190KIT you will connect the following wires from the ModuLite to the following functions on your GLC 300: Yellow - Left Turn Green - Right Turn Brown - Tail/Running Lights Red - Brake Lights White - Ground If...

  • Brake Controller Recommendation for 2015 BMW X5 with Factory 7-Way
    Since your 2016 BMX X5 has a factory 7-way already all you need is a brake controller to activate your trailer brakes and you'd be set. So the easiest to install brake controller that also works really well is the Curt Echo Mobile part # C51180. Basically this just plugs into an active 7-way and once you sync it to your phone it's ready to go. This brake controller is proportional which means it senses the amount of deceleration your tow vehicle is applying and applies the trailer brakes...

  • Trailer Wiring Harness Availability for a 2008 Lexus RX400h
    Some vehicle manufacturers will run the tow package wiring on vehicles, but they will not include a trailer wiring harness if the vehicle is not ordered or purchased with the tow package. There is no aftermarket plug-in style trailer wiring harness for the 2008 Lexus RX400h. This may be a dealer only item if it exists. At this time, the only aftermarket wiring harnesses available for your vehicle are hard wire kits with a powered converter like part # 119190KIT. If you would prefer...

  • Trailer Wiring Recommendation for 2014 Honda Ridgeline
    You might be the first person to request a universal trailer wiring options verse a custom fit one that doesn't require splicing! We can help though. For a hardwired harness I would recommend the # 119190KIT as it basically can fit any vehicle due to it's universal nature. I would still recommend the # 118491 though as it's going to be easier to install and not require any vehicle wire splicing.

  • Recommended Trailer Wiring Harness for 2004 Volvo XC90
    The 119190 and the 119179 are two completely different applications, and the 119179 is NOT a replacement for the 119190. The # 119190 is rated for higher amperage and would be called for on vehicles with a highly sophisticated wiring system like that of your Volvo. Your Volvo uses a multiplex wiring system, and the 119190 will work on almost all vehicles with a multiplex wiring system and it has been tested and found to work very well on your vehicle. The # 119179 has a lower amperage...

  • Trailer Wiring Harness for a 2013 Mercedes GLK350
    For 2013 there were 8 versions of the Mercedes GLK. Diesel motors were available on the 200, 220, 250, and 350. Trailer wiring harness # 119190KIT is a universal type of item though and should work just fine on your 2013 GLK350 even though it is not officially listed as a fit.

  • Does the Trailer Wiring for a 2011 BMW X5 Have to Route Through the Rear Door
    If you can find a grommeted hole in the rear cargo area of your 2011 BMW X5 you could route the 4-way through that, but you should note that it is actually preferred to keep the trailer wiring stored on the interior of the vehicle. Having it stored there keeps it protected from corrosion and damage from debris that could be flying around under the vehicle as you are traveling. The thick rubber seal on the rear door frame will protect the wiring as you shut the door on it as well. I...

  • Adding 7-Way to John Deere 4640 Tractor
    What you would need to do is use the part # 119190KIT to tap into any available taillight circuits so that you could give yourself a fully functional 4-way. From there you would use the part # 37185 to convert it to a 7-way. If you don't have brake lights on your tractor currently you'd be limited to basically just being able to operate the turn signals and hazard lights.

    I can help you find what you need to get it installed but there isn't a direct plug-in wiring adapter for the Prodigy P2 # 90885 that's confirmed to fit your 2017 BMW X5. You can install a 4-way trailer connector on the back of your X5. Use # 119190KIT for this. It needs to be hardwired into the BMW's wiring. Then use our # ETBC7 kit to convert the 4-way to a 7-way.

  • Parts Needed to Install Redarc Tow Pro Brake Controller in 2011 BMW X5
    A diode is not needed to install a brake controller in your 2011 BMW X5 like the Redarc Tow Pro part # RED44FR that you referenced. The red wire of the controller would run directly to a brake signal at the pedal and you'd be set. You can't use wiring from the # 119190KIT as this signal is also shared by the turn signal circuit so you'd have the brakes trying to activate with the blinker. This is why you need just a brake light circuit. The other kit you need is the part # ETBC7 which...

Once you splice into the correct wires all you will need to do is run the power/ground wire and you are good to go which you can see from the attached install video.

  • Trailer Wiring Harness for 2011 Volvo XC60
    The correct trailer wiring harness for your 2011 Volvo XC60 is part # 118739. This wiring harness is vehicle-specific and would be much easier to install than the harness you referenced, which is a more general application. A wiring connector would plug inline behind each of your tail light assemblies, one wire would ground to the vehicle, and a power wire would run under the vehicle to the positive battery terminal using the provided fuse holder.

  • 2014 VW Tiguan 4-Way Trailer Wiring Harness Recommendation

  • Recommended Trailer Wiring Harness for 2019 Nissan Leaf
    Although the # 119190KIT you'd looked at would work, the Curt # C56227 would be easier to install. The wiring harness would plug inline between the taillight assemblies and the vehicle's taillight wiring harnesses, with one remaining wire that needs to be ran to the battery via the included 10A fuse. Although you'd have that one wire to run up front, you won't need to cut or splice into any of the factory wiring. If you don't already have a hitch, I'd recommend the EcoHitch # 306-X7221....
