The kit was fine. It was missing a couple of ring connectors and test light will require some additional wire to use it. The video on your site was very helpful. One more suggestion would be to use electrical tape instead of the zip ties where the wiring must be routed next to the hatch hinge. if there is tension the zip ties might break, but the tape will flex a bit.

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.

I ordered a hitch and a modulite controller. Upon arrival the box was mangled and only the hitch was inside, I reached out on a holiday and they were prompt to respond and send me a new one. I haven't installed it yet but as a company review worth the 5 stars. I'll try and revise review once installed and has been on for a while.

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)!

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.

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.

Everything seems to be high quality. The blue splicing connectors even come with dielectric grease in them to help keep the connections from corroding over time. The instructions are pretty good and etrailer’a videos really help with the install. My only complaint is it seemed to be missing a few small parts like the yellow butt connectors and the ring terminal was too small for my application. Besides that, it’s great

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.

The equipment arrived complete and in good shape. However the most impressive thing about this, and earlier orders with etrailer was the customer service. When they saw one of the items was delayed they reached out to offer an alternative. They also kept me well informed of progress and when it was shipped/delivered. The videos on their products including installation are also very detailed and helpful. Great place to do business with.



- 119190KIT

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 am a DIY guy who does not have any experience on electrical. Got it today, and installed in with not much issue. I went online/youtube to get more information etc. Took me a while to figure out the circuit tester that came with you kit was not working at all. I ended up buying a tester from [online], which basically confirmed that the tester came with the kit was defective.

I have to give it a 4 star because wire for right turn signal is too short to reach that side had to splice extra wire. Bought harness for my Audi A4 before that was perfect.

I recommend watching the video that we have on a 2014 Audi Q5 that shows show to run the wires so that you will not need extra wire. It starts at mark 5:33 in the video.

It took some time and trouble to figure out how this correlates to the installation video (for the Curt model, which has fewer wires). Once the right wires were identified, it was very simple and straightforward. The system works like a charm, and I've already towed a U-Haul trailer. Depending on the vehicle, I would recommend getting some 3/8" wire loom ($1.99 @ Home Depot) to protect the power wire from abrasion/cuts if you route it along your car's underbody. The included instructions (online & paper) are too generic to be useful, and the vehicle wiring codes (types of wire systems: 2-wire, 3-wire pulse, etc.) don't have a reference on the TowReady website. Moderate gripes, but some streamlining would've saved me unnecessary troubleshooting. All the parts you need are included, with extras just in case.


Comments
Hey Jameel, not sure if things were different back in 2012 but for folks ready your review today, I suggestion 1/4 wire loom instead. The 3/8 diameter is larger than needed and leaves more play.

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.

Thanks for your business and your detailed review regarding the wiring, Frank. Depending upon the factory product run, the vehicle wiring colors may change. We always recommend testing for function before connecting the wires.

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!

  • Can Power Wire for Trailer Wiring Harness be Connected to 12 Volt Outlet on 2013 Volkswagen Tiguan
    No. The issue is that wiring harnesses # 119190 or # 119190KIT are tested and rated for a connection to the battery only. Installing them using any other method could cause undesired operation. Also, if connected to a 12 volt outlet, you will lose that level of circuit protection between your 2013 Volkswagen Tiguan and the trailer. Routing the wire is just time-consuming but not really difficult. I have included a link to a help article with tips on routing the power wire for you.

  • Installing Trailer Wiring Harness Part #119190 on a 2013 VW Tiguan
    Some vehicles combine stop and tail light functions onto 1 circuit and then also have an additional tail light function wire that is independent of the stop (such as your 2013 VW Tiguan). These vehicles will require that you attach the trailer light power module red “stop” wire to the same combined circuit on the vehicle and then attach the brown “tail light” circuit to the independent circuit on the vehicle.
