Video Transcript for Trailer Wiring Harness Installation - 2014 Volkswagen Jetta Sportwagen

Today on a 2014 Volkswagen Jetta Sportwagen, were going to install part number 119179kit from Tow Ready. First thing we need to do is get access to the wire harness were going to work with. This will behind the panels right behind the tail lights. To start off we need to remove some interior components. Were already removed the spare tire cover and a spare tire itself. At this point we go ahead and remove the thresh hold.

There are two fasteners that are horizontal on the inside edge of the thresh hold. Take a flat screwdriver to unscrew them. Well go ahead and pull it towards the center of the vehicle just gently and then pull at the same time then the whole thresh hold will actually pop loose. Once we have that accomplished we need to remove the lid that coves the spare tire area as well. There will be four screws that we can remove. There are two additional fasteners on the other side of the cover; well have to remove these as well.

Once we have that out of the way we can go ahead and work on the perimeter that goes around it. This is a frame that the lid sits on top of. This frame is in two pieces and has a covering on top of it as well. The other coverings loose so we can find the fastener that holds it in place. There are two fasteners for each side. Theres a screw that goes horizontal towards the back seats.

Theres a plastic nut that holds the other half thats closer to the spare tire well. Well go ahead and remove the fasteners then we can go ahead and take them out. We can lift up on it and then pull towards the front to release it from the pin thats in back. This frame work has a left and right hand side. Once both sides are removed we can go ahead and work on the side panels to get access to our wiring. Well start by removing the tie down fastener at the top of a side panel.

Starting from the bottom, well feel around for fasteners and look underneath the edge you can see them and well just pry them loose with a trim panel tool. Where panel meets the roof panel we need to separate there as well. Then we can get our panel pulled free and we can do our work. Well have to do this on both sides of the car. Once our panels are free we can go ahead and start working on our modules. First off well go ahead and work on the drivers side. Now well disconnect the wire harness from the tail light. Theres a very small tab on each half of the connector where you push in and then pull the whole connector back it comes loose. Where our wire harness plugs into the back of the tail light is where were going to make our connections. We need to test which wire does what function. First off well go ahead and use the ground screw that comes with the kit and run it through the sheet metal behind the tail light. Well use that for our ground for our tester. Then well test the pins on the connector. Well start off looking for our running lights. When we test it we found out that gray with a black stripe is the running lights. Using the provided quick splice connector well go ahead and connect that wire to our brown wire. Next well go ahead and look for our left turn signal. In testing we found out its dark gray, white stripe. Connect the left turn wire to the yellow wire. Now we need to look for our brakes. With the brake petal pressed down well look for that circuit. That one looks like dark gray with a red stripe so well connect that wire to a red wire from our module. Now there are two wires for our module that are red, we want the smaller of the two. Now well also take the white wire with the ring terminal and we need to ground that to the body so well attach that to the inside sheet metal of the vehicle. Now we need to get a signal for our right hand side so well take a green wire and run it over to the right hand side. Once again well go ahead and test our wires. On this side theres a inaudible 00:04:19 ground that we can use for our tester. We found out that the dark gray with the green strip is a right turn signal. Then well go ahead and make our final connection with the quick splice connector. For our green wire well go ahead and use some loom clamps to help hold them in place. This will keep them hidden underneath the thresh hold. The part number well be using will be a0250. The screws were using are part number sa1131822. Now well go ahead and work with our big red wire from the module. Thats going to connect up to our black wire and supply the kit. This will need to be ran up to the battery so well take the yellow butt connector, connect it to the black wire and then connect our red wire to it. Well also take our module and well connect it to the sheet metal right next to where we installed our ground. Well go ahead and leave that alone for now. With our black wire connected we need to run it to the outside so in this case theres not an available grommet thats close by, well go ahead and drill a hole through the sheet metal in front of the spare tire area. Were drilling a small pilot hole first, then well follow up with a larger hole that will match the rubber bushing that were using. Once we have it installed well go ahead and take our wire and run it through. I wont take up all our slack, well go ahead and leave some on the inside route it on the inside so we can hide it underneath the carpeting and panels later on. Well use some sealant around the grommet on the inside. When everything secure on the inside of the car well go ahead and run a wire underneath the car up to the front towards the battery. This case were going to go over the exhaust heat shield then well go and follow the brake line, follow that up all the way up to the engine compartment. Then well go ahead and run our wire from the bottom towards the top. Now to do this we can use a stiff piece of wire or in this case were using a piece of air line tubing that we can work our way up from the bottom towards the top. When we pull our wire up we want to make sure we stay away from anything that moves like suspension or steering components, come up by the fire wall and then well work our way around the battery compartment. Well go ahead and cut out wire to length then well add our fuse holder. Well cut the fuse holder in half, one end will get a ring terminal and the other end will get a butt connector that will connect to the black wire. Once our wire is connected well go ahead and connect to the positive terminal on the battery. Now a lot of times the threads dont allow you to inaudible 00:07:02 that all the off. In this case were actually going to split a ring terminal a little bit, run it around the stud and then tighten the nut back down. Then put our lid back on to the case. We can go ahead and zip tie our wires as needed to make sure theyre secure in the engine compartment then we can go ahead and install a fuse into the fuse holder. As we reinstall our interior components well take our four pull wire and route it through the back side of the compartment on the drivers side. Following that we can go ahead and reinstall our interior components in reverse order of what we did before taking them out. Now we can go ahead and show how it works. All we need to do is pull out our wire harness and shut the hatch on it. We want to make sure that we stay away from the center so the latch won't damage the wire and also the seal around the door is thick enough where it wont hurt anything if you shut the door on it. At this point its a good idea to go ahead and check the wire harness. Well take a ground lead for our tester and connect it to the white wire. Then well test our brown wire for our running lights work. Well go ahead and test our yellow wire for our left turn circuit and our green wire will be a right turn signal. Now our brake signal should be a signal from the green and yellow wire. With that that will finish it for part number 119179kit on this 2014 Volkswagen Jetta Sportwagen. .

Was having difficult time finding a shop to install trailer hitch wiring on my Land Rover. Professional install shops who would offer to install quoted very high prices. Watched installation video for 119179KIT for 2010 Land Rover online. Bought your KIT and I installed as per video in about two hours. Could do another install probably in half the time. KIT included everything I needed except about two more feet of 'green' wire to reach passenger side tail light assembly on the Land Rover. Completed installation and ran test on wiring system with everything checking OK! Had a great time doing the install and would highly recommend your products to others. Thank You! 664246

I purchased a class 2 Draw-tite hitch, drawbar with 3 1/2 " rise, 1 7/8 ball, and the circuit protected modulite 4 pole harness kit for my 1991 Chrysler New Yorker. The shipping was incredibly fast. Everything fit well and easy install. I saved $200.00 installing it myself. Now I'll be able to tow my 14 ft aluminum fishing boat and catch me some nice trout. Thank's for the good products and fast shipping. Here's some pics. You can't even see the hitch unless the drawbar and ball are on. Lou 39159

I bought the Draw-tite hitch and the Modulite wiring harness for my new 2013 KIA Soul and was overall very pleased with the service and the product ..... I'm glad I watched the installation videos when I ordered the items as I was unable to find them when I went back in to doublecheck a couple of details ..... the Modulite wiring harness did not come with any instructions at all ! And the hitch instructions didn't show the secret trick about lowering the muffler .... the videos were VERY helpful but I don't understand why I couldn't find them when I went back in ( admittedly, on a different computer ) to check .... But everything went together very well and is working perfectly ! E-trailer was very prompt, very competetively priced, and very helpful with their online videos ..... thanx, E-trailer ! 89335

Did your kia soul have led lighting? If so which brand did you buy and was it easy to run all the wires with go results. thanks jack

You can use the 119179KIT harness with both LED light and non-LED versions of the Soul. Since the 119179 harness has its own power feed, the LED lights would be protected. We have installed the kit on a 2013 Soul and shot a video of it that I have linked below. If you let me know what year Soul you are working with and whether or not yours is LED, I can check to see if there are other options.

Toyota 4Runner

Where do I start? About a year ago I purchased a trailer adapter for my 4Runner after recommendation from etrailer employee who helped me navigate the website. So I proceeded to install but then I noticed that turn signals and brake lights come on only intermittently. After thoroughly checking my work and all of the wiring on the trailer, even tried my buddy’s trailer only to show the same symptoms. I get on the phone w etrailer and describe the issues, to which their reply was maybe the adapter is defective and we will send you a new one. I agreed and went ahead to install second new adapter but there was still no changes. It was only a third time I spoke to yet another “specialist” at the etrailer who noticed that my truck needs a 6 wire harness adapter and that 6th wire goes directly to the battery. In conclusion my truck needed constant power from the battery for that adapter to work, because apparently there wasn’t enough juice for the 5 wire adapter to power brake and signal lights consistently. Ended up paying extra $60 for adapter with an extra wire and that fixed the issue, my turn signals and brake lights come on every time. After spending close to 20-30 hours tearing plastics on the truck, then installing back and forth 3 times diagnosing and testing, in the hindsight I wish i reached out to local shop or trailer store and probably saved me much headache. 646537

It does what you need. I'm about to purchase my third of these - so I must be happy with it. The first two were on my '94 F150. When towing a trailer that has more than just a single pair of stop-turn lights, you need a powered adapter to keep from "dimming out" the tail lights/signal lights on the truck. My first one failed after a few years (tail lights always on, even when the truck lights were off!) so I bought a replacement. It would be nice if they lasted the life of the vehicle, but that's just not the standard for aftermarket and towing electronics - presumably because we consumers are so cost-sensitive. Now I've sold that truck and bought a new Tacoma. After installing the "plug and play" adapter, I find the tail and clearance lights are bit dim (6 bulbs total on the trailer) and while the factory setup has enough power to power either turn signals, it can't do the emergency flashers. So it's time to buy another 119176. 3432

Appreciate your positivity although it seems you had some disappointments..

With that number of lights, depending on the bulbs, the 119190 might be a better solution. It will support a greater light load than will the 119176. It probably would have lasted longer on his older F-150 too.

I'm only sorry I didn't take photos of the installation of the trailer wiring. I have to say, it was the easiest most enjoyable install I may have ever done of this kind. I'm not the handiest when it comes to this type of thing, but coupled with the complete wiring and hardware setup, it really made all the difference. The video that accompanied my specific vehicle also made a world of difference, major high marks for this. The only thing that may have helped was a bit longer wire for the passenger side (green) wire, but that's probably not even worth mentioning though I did. I'm putting together a tow package for hauling a light motorcycle trailer, so I figured I'd try this myself and I'm glad I did, great instructions make all the difference! These guys include everything right down to the wire ties and it's all top quality heavy gauge wire. Thanks again and I'll be using you guys for sure in the near future. Graham 240723

Thanks for the follow-up. All is well with the wiring, its also strange synchronicity as I just bought a little trailer last week and for the first time in a year I used my new wiring harness again. Perfect, thanks again!

Bought this kit for my 04 WRX because it does not have any trailer wiring harness. Install was a sinch, especially for anyone somewhat knowledgable with automotive experience. Just pulled back the trunk lining and tapped into my tailights. As for the big wire you have to run to the battery, i suggest you take the time and pull your interior trim out and run it inside the vehicle and throught the firewall, dont just ziptie it up under the car. Works exactly as its said to, already have made two trips with my trailer and all lights have been in perfect working order. Also happy with ETRAILER's shipping, arrived was sooner than expected! 61111

Product doesn’t work. Installed correctly right signal connection tested good in car but there was a short in the amplifier box which turned the left signal on with left or right signal activation. Horrible costumer service. They are charging me to return it. I am a repeat customer but will never buy from them again. 504391


Comments
To test the if the converter box is bad, you can use a tester and test the incoming function on the wires, and the make sure that same function is transmitted through the converter box. If it is not, then the converter box is bad.

The harness and hitch have worked great. I see a lot of trailer hitches that rust very quickly. This one still looks very good. I just recently ordered a hitch for my Ford Ranger from etrailer as I was happy with what I had purchased before.

Both the dealer and U Haul said they couldn't do a wire package for a 2013 Infiniti EX37. This kit worked just fine. Could have used instructions for the lighting adapter, but watching the video a couple of times and taking notes for which color did what seems to have worked. Delivery was quick. Thanks for the tester, couldn't have done without it. (Use a leather glove on the hand holding the wire!) 126924

I WAS AMAZED AT THE SPEED OF DELIVERY. I HAVEN'T INSTALLED IT YET BECAUSE I AM ILL AND IT IS TOO COLD, BUT THE VIDEO MAKES IT SEEM EASY TO DO. I AM EXCITED ABOUT THE NEW WIRING SYSTEM THAT WILL ELIMINATE THE PROBLEMS THAT I HAVE HAD WITH EARLIER WIRING SYSTEMS FOR MY OLDER 2002 MERCURY. I WAS VERY PLEASED AT THE DELIVERY OF MY HITCH ALSO. IT CAME QUICKLY AND EVERYTHING WORKED OUT VERY WELL. INSTALLATION WAS EASY AND STRAIGHT FORWARD. I DID IT IN MY DRIVEWAY. I JACKED UP THE HITCH TO TOUCH THE FRAME AND MARKED IT OFF FOR DRILLING. I DID IT ALONE. WORKED GREAT. I DRILLED THE HOLES, THEN BOLTED ONE AT A TIME. I HAD A NEED TO CALL AND ASK QUESTIONS, AND FOUND IT EASY TO DO BUSINESS WITH THESE PEOPLE. THEY HAD THE ANSWERS AND WERE VERY HELPFUL. THESE GUYS ARE THE BEST. 325203

I purchased this kit to install in my 2003 Mercury Grand Marquis. This wiring kit is just the ticket for getting your hitch up & running. You need a wire stripper/crimping tool, some black electrical tape, and definitely a creeper when you run the wire from the module to the battery. I would also recommend a set of trim removal pry bars as demonstrated in the eTrailer video. This kit installs easily, but take your time, especially when routing the wire to the battery. Make sure you protect the wire from the rough/sharp edges you WILL encounter! I wrapped electrical tape around the sharp edges and around the wire, should last a while. Also, use the included zip ties where necessary so it doesn't get hung up on something. To use the tester, ground it out (see pic) and come through the insulation at an angle instead of straight down (the lead will 'give' otherwise). I routed the battery wire through the rubber body plug, since there wasn't an easier way I could find. I will probably buy another plug and make a small cut for the wire to pass through later (a little silicone or rubber cement will seal it off). This kit might cost more than you might like to spend, but I highly recommend it for a proper and safe wiring job. 19791

  • Difference Between Tow Ready Trailer Wiring Harness # 119179 and # 119179KIT
    You're correct. Using the 'KIT' suffix after the part number provides the power wire feed to the vehicle battery and the fuse holder, which you won't need (assuming that your existing power feed and fuse holder are in good shape). The # 119179 is exactly what you'd need. However, before installing the replacement, you'll want to closely examine the wiring on the trailer to determine if there was a short in the trailer wiring that caused the converter's demise.

    The difference between the # 11978KIT and the # 119179KIT wiring harnesses is that the # 119179KIT includes a power wire that provides the power for the trailer lighting, directly from the vehicle batter.

    All of the available trailer hitches for a 2004 Volvo XC70 are class II hitches with a gross trailer weight capacity of 3,500 pounds and a tongue weight capacity of 300 pounds.
