Video Transcript for Tow Ready Wiring 119178KIT Review

Today we're going to review Part No. 119178KIT: Tow-Ready Upgraded Circuit-Protected Tail-Light Converter Hard-Wire Kit with the four-way flat trailer connector. Also includes the circuit-tester and the five wire connectors. Now, this will provide a four-way flat trailer connector at the back of your tow vehicle to power your trailer's signal lights. It has short-circuit protection, which will safeguard itself and the tow vehicle against any harmful electrical shorts or mis-wire situations. The circuit will automatically reset once this module cools down.

This will also adapt a three-wire system on the towing vehicle to a two-wire system on the trailer. Basically the difference is, a two-wire system will have the same bulb for your stop and turn signals. A three-wire system will have separate bulbs for the stop and turn signals. This will also work with either LED or incandescent bulbs, and it will work with most vehicles that use a multi-flex wiring system for their lighting. And again, I mentioned it includes the circuit tester and the five quick-splice connectors to help in insulation. Also, on the four-way, you can see it includes an integrated dust cover, which is nice, because when it's not plugged in, you can just put your dust cover over that, and it will protect the terminals from any elements or from any damage.

Now, the pigtails on the wiring is about eighteen inches long. The bonded wire for the four-way is about sixty inches long. Now, a few specs on this. The maximum stop and turn light capacity on this is 2.1 amps, and on the maximum taillight capacity, it's 7.5 amps. Basically, when you go to install this, what you'll do: This will be your wire into four-way that will run out the back to your trailer. This wire is what you're going to use the circuit tester and test the wires in your tow vehicle, and then hook the wires up correctly.

What you'll do: The white wire with the connector here, that is what will connect to a good, clean ground. The other wires: The brown wire will connect to the tail lights. The yellow would be for your left turn signal. The red is for your brake light, unless it's a two-wire system, then you'll just ground that. If it's a three-wire, then you'll connect it to your stop light system.

Then the green wire is for your right turn signal. Again, it includes a circuit-tester that you can use to test the wires on your car to hook it up correctly, and then these quick-splice connectors to connect all the wires. That should do it for the review on Part No. 119178KIT. This is the Tow-Ready Upgraded Circuit-Protected Tail-Light Converter Hard-Wire Kit with the four-way flat trailer connector. .

I would not say this was an "easy" install, but for the significant savings in cost of an OEM harness it was worth it. The OEM harness had to be installed by running from front to back under the drivers so the time involved may be a wash. Buyers need to understand this unit must be installed by tapping into the existing rear lights by opening up the driver and passenger side panels in the rear compartment (next to the spare tire wheel well). If you do not want to mount the "harness box" inside the spare tire compartment, there is a great place behind the driver side panel, however, you will have to lengthen the right turn signal wire (green) to reach the right light. I ran the 4 plug trailer harness through the license plate rubber plug by cutting a slit in the plug and running the 4 wire set through it. The bumper will have to be removed (don't have to take off bumper cover) by removing the 2 screws on each side of the bumper. Depending on how you route the harness through the metal bumper frame that is now exposed, and how long of a tag end you want, you may have to lengthen the 4 wire set with a splice, I did. You may be able to avoid any splice by mounting in the spare tire compartment. Trailer lights are bright, no dimming at all. 41083

The 2 stars are for the lack of ANY correct instructions ( none were in the package, so i relied on the videos published by etrailer) for my 2006 Toyota Avalon . Once i determined the proper hookup the unit itself seems fine . The closest instruction i could find was the video for the 2007 Toyota Avalon . i used it for the instructions. Turns out, it is not correct for the 2006. After several hours of volt and ohm meter readings and swapping cars to verify that my trailer harness wiring was OK , i noticed that the low side of the bulbs for the rear lights were not attached anywhere to a car chassis ground. Then i determined that the white ground wire and lug( car side wiring of the unit) for the 119178 was NOT to be attached to the car chassis ground but to a low side wire in the wiring harness( black and white). Everything worked fine with that correction. I also found the note attached to the red wire confusing as it had different attachment instructions that depended on whether one was using a 2 wire or 3 wire system. Again no description to help me tell what system i had( 3 wire). Instructions and or a schematic would have raised my evaluation to 4 stars( 5 stars being reserved for longtime reliability). 315613

took a bit to figure out how to get it over both bumper screws. turned out i need to do the one opposite the exhaust 1st. had to disconnect the mount for the fuel line/filter. after installation the fuel line/filter mount plate doesn't fit into the frame but since the arm for the hitch goes through the fuel line/filter assembly it kinda doesn't matter, the hitch is holding everything up. getting those bolts and plates together seemed impossible at 1st. i ended up tying some box string around the tip of the bolt (wrapping around the threading), taped off the tip to keep the string on, and dabbed some oil onto the bolt. then i thread the string through the plate opening and shoved 1st the bolt then the plate into the access hole on the car frame. this way i was able to line up the plate hole and gentle work the bolt back to the hole, then vertical to drop through the opening. i had to use a thin allen key to move things around as well but it worked and honestly it was super easy, took 5 min/bolt including taping off the string. 25155

Great wiring harness at a great price. A little difficult to install (not the wires fault, it was all due to the car itself, which was virtually impossible to access the rear wiring) however, once I got to the wires, the install was very simple. I could have used some paperwork telling me what the wires were, but I read other reviews beforehand saying the same thing, so I was not surprised. I LOVED the included tester! VERY fast shipping, too! 94847


One year later... still a great hitch wiring harness. Has held up well with moderate use.

I needed a hard-to-find hitch for my '98 Montero, overnight, no less. I ordered this part along with a harness from etrailer with overnight shipping. I don't live at the end of the world, but you can see it from here, so I wasn't optimistic about everything arriving on time for my trip. Shortly after the order was placed I received emails from etrailer's staff indicating the part wasn't at their main warehouse and would have to be sourced from another. They updated me throughout the day and the following morning. The parts arrived early afternoon. Installation took little time at all with their helpful wiring harness install video. Great thanks to George J, Bridget A and Madison H and others for seeing this through. 342774

I just installed my trailer wiring harness I purchased from For the do it yourselfer that can trace and figure out which wires are needed to splice into, it is a very good kit. I chose to solder my connections instead of using the supplied crimp connectors. I've seen these connectors corrode after a few years and then you have to eliminate it and fix the connection. Also, I chose to attach the converter to the frame with a heavy duty tie strap instead of using the adhesive pad that is attache to it. The only other thing I might suggest is a self drilling screw to attacht the ground wire. Having said all that, I would highly recommend this Kit. It saved me between $400 and $900 dollars according to the horror stories I've read online. You Guys need to get this product out there, maybe go to some Dodge forums. Good Job. 65616

Wires weren't marked as to what was what, with exception of one. figured they were pretty much standard wiring colors for trailer, still had to find out to make sure. Little included circuit tester works well, saves time having to find mine. Other then the unmarked wires, product works well. That's why I dropped it one from top rating 88367


Everything is working great, was easy install. Thanks for followup.

I bought this wiring along with the HiddenHitch, hitch ball, and ball mount. The wiring assembly was clearly marked but the wire colors don't match up with the Honda Element's wires- no big deal, just use the little doodad thing that is included that lights up when you poke the right wire. (I obviously got a friend who knew what they were doing to do that part.) The most problematic part was figuring out how to route the wires to the brake lights- I looked at the video clips provided, but they were only somewhat helpful given that none of them were Honda Elements. I ultimately came up with something much simpler (a 1/4" drill bit is a beautiful thing) that took far less time. The only thing on the wiring assembly that would be more helpful is if the green wire that goes to the right tail light was about 3 inches longer. 44214

The new hitch arrived today, everything was in the box that I ordered. Very Very nice product. I must admit I was kind of expecting a cheap looking hitch. But this is first class stuff. I'll be using it on my Yaris shortly. Rather than spend a bunch of money on a pickup truck. A 4 x 8 trailer will be hauling my home repair products from now on. Also, I will be coming back to "etrailer" for a bike rack to fit the new hitch. I highly recommend "etrailer", with the on-line assistance and very nice products. You can't beat the price either. The local uhaul wanted double the money I spent at "etrailer" to install the hitch and wire it. It took me 25 minutes to install the hitch and about an hour to wire it. (lot's of plastic to remove and reinstall) Thanks again guys......Happy Customer. 25760

I installed it on a 2003 Mazda Protege. It was easy to install and it worked correctly. You will need a second person to work the lights so you can identify the correct wiring. 233191


After a year the wiring is still working correctly.

This product worked exactly as advertised- it spliced in well to my car's existing electrical system and provided the appropriate signals to the trailer. Combined with a shop manual for my car, it was trivial to set up and install. That said, I have some concerns about the long-term viability of the splice connectors used- it seems like a design that would allow corrosion to start in the electrical system. When I have time, I'm thinking of switching to a more robust solution that would probably involve soldered and sealed connections. That said, for a quick-and-dirty lighting solution, this kit works very well. 23690

Ordered the 119175KIT for my 2006 Honda Element EX. Ordered on a Tuesday with two day shipping, item was shipped on Wed and I received my package on Friday. I watched the installation videos and did some additional research on how to get to the Element wiring, and was on my way. Took my time with the installation and the entire process went smoothly. Rented my Uhaul trailer on Monday, plugged in and hit the road. The included wiring tester was key. Also, there are no paper instructions included with this kit. The videos are key. I would definitely go with again. 12384

At first I was a bit confused because the video instructions for my Mercury Villager gave a different part number than I recieved, but I soldiered through and was successful. One needed help would be- tell us how to free the harness connector from the car. I couldn't so I connected the wires in very a cramped space. Also, my converter had no labeling of wires as I saw in the catalog. A friend of mine has a Draw-Tite unit and his converter is labeled. He said it made it real easy to hook up. I am satisfied with what I got and it WORKS. I also really like the little tester, it came in real handy. 125545

Instructions did not come with the device but I was able to find information online in the form of PDF files albeit, not with specific information for my old 2002 Malibu. It would have been nice to find wiring charts with color codes for my exact car. Also, I did not find any information that really made clear to me or defined what a 3 wire as opposed to 4 wire system is. My car certainly had more than 4 wires running to the stop and tail lights. But with the included tester, I was able to figure out which wire was which and the system works properly. 163591

Installation went Just about as I expected. Working alone it took me about 1 1/2 hours, not counting the wiring harness ( 62 year old guy). I installed one of your hitches several years ago so I knew about what to do. The video was a big help. The only tools needed were a ratchet, screw driver,ramps,and a can of WD40. I left one of the 3 rubber exhaust supports (hangers) in place. It gave some support to the muffler so the pipe wouldn't bend, but everything dropped down low enough slide the hitch into place. 2007 Kia Sportage w/ single exhaust. 214621

Ordered on wenesday , received it yesterday ( Monday ) the online video is very helpful and we put it under the car today ( Tuesday ) did take about 45 minutes ( its kinda though to get some of the bolts started even with the steelbrush to clean the holes , little bit of liquid wrench helped . Only thing I didn't do yet is the wiring harness for the trailer lights which came with no instructions at all . So I hope there is a video or something on that lol. Al in Al I am pretty happy with the product and the end result . Ron Klap 163989

Great customer service - as always! The kit arrived without instructions. Fortunately the manufacturer's data sheet was available on the etrailer web site. The data sheet was brief and the etrailer installation instructions were more helpful in understanding what was required. The actual installation process required about 10 minutes once the wiring connections were understood. The device successfully passed it's functional checkout but actual use will be required to determine if it truly meets the use requirements. 211697

I have a 2005 Suzuki Forenza Wagon. I tried to get the hitch wiring installed by U-Haul (don't do it for my car) and a Suzuki Dealer (couldn't or wouldn't figure it out). Finally I found this wiring kit. I watched the video on the web page and gave it a try. Done in 45 minutes - exceptionally simple. Tester worked great identifying the right wire to connect to. Why oh why did I just not do this in the first place. Also the eTrailer site did a great job recommending the right part for my particualr make/model of car. 13786

by: Perry Y12/05/2011

Bought this for a 2005 Honda Element. I would recommend the kit for a generic harness, but not for the 05 Element. In order to install it, it requires the removal of the rear trim, which also requires the removal of both rear seats. The 05 element has a trailer adapter built into it, which I didn't know prior to buying it. So if I had to do it again, I'd buy OEM or OEM equivalent so it plugs right in. While the honda kit requires some panel removal, I don't think it's quite as complicated as this kit requires. 27729

Product arrived in 3-days using the least expensive ship offering. The instructions were very well done. The hitch mounted on the Honda Civic with zero issues. The secret was reading ALL of the instructions. The wiring kit was complete and worked perfectly. It did not include instructions, but it is a rather straight forward process splicing the labeled wires to the appropriate car wires. This is my second kit from etrailer and I'll be back when I purchase another vehicle in need of a receiver hitch. 93576

Hi E-Trailer ! You guys are great. Excellent customer service both times I have ordered from you. Love your order tracking Map. 119178KIT : Good Converter. Unit came through with Decal on converter labeling all wires as to function. Wire length going to vehicle side on install could have been longer but was adequate. Trailer side wiring good length with nice Flat connector. Converter body comes with two way tape to attach to vehicle body. After install worked perfectly. Thanks again. Paul 92038

It's too early to be certain, as my trailer is not wired up yet, but I think this worked out fine. Weird that it had no instructions with it, but the included test light and labeled wiring on the box made it not too hard to install. Wire lengths were fine, although not generous. I plan to run it out the trunk, right over the weatherstrip, as my trailer use will be occasional and short term. Otherwise it could be hard to come up with a non-destructive way to put the connector through the sheet-metal. 25995

Product was great. Quick delivery and the video on how to install was most helpful. Easy installation for the wiring harness (15 minutes) with the converter from two-wire to three-wire. I previously purchased my trailer hitch from etrailer and again found the video very helpful and had it install in 15 minutes. Would recommend both of these produces. I tow an 8-kayak trailer with my 1998 Honda Civic and these produces make it all work smoothly. Now if I could just learn to back up. 193030

2008 Toyota Yaris Hatchback. We found the splice connectors to have severed the wires on 2 out of 3 three wires used on. We replaced with butt connectors. The tester lead is a great add in for people who dont have one already, and it actually works. Plan on this taking about 2 hours even it you have help. You will be taking the back of the hatchback apart to complete. Would have prefered a Plug in wiring unit-but I can now see space concerns preclude this being made. 60582

what a nice easy install. I didn't even get instructions with mine and with the included 12 volt test light it was painless to find the leads I needed. it took more time to figure out how to run the pig tail out of the car than it was to connect the clearly labeled wires with the supplied connectors e adhesive on the back of the box sticks to any dry clean spot perfectly. . just make sure you do it right the first time. no second chances if you stuck it wrong. 38103

by: Gary W.10/07/2011

It includes a circuit tester! I am giving this one rating less than excellent because the wire to the right turn signal needs to be at least 6 inches longer. I had to get creative with the placement and routing to make it work and keep it out of harms way and a place where the box would not interfere with the trim installation. Otherwise the video was helpful and it was very easy to install. Very nice that the tester is included. 2009 Kia Rio5 25220

Very easy to install since I was replacing an existing etrailer wiring harness that was electrically damaged by a friend's trailer (that one had a short). Took only about 15 minutes to cut out the old one and splice in this new one. I tried it on my trailer and it works properly. I recommend this one since it has overload protection which helps me since I tow trailers that I borrow from friends and never really know the condition of the wiring. 56272

The hitch mounted to the car in less than 30 minuets once I had cleaned up the welded nuts in the frame of the car. The welded nut were so rusty and full of road grim because the car is over 10 years old. I used a wire brush from a gun cleaning kit, in a drill, lots of liquid wrench and a nut driver to clean the threads. I would recommend this hitch to anyone. The wiring kit was also easy and encluded every this you need except tools 10993

Wiring harness for Toyota Avalon The wiring harness arrived as promised and I was a little surprised that it was without any instructions. I thought that since I had specified which vehicle the unit was to be installed in that some hints to where the best location would be to tap into the vehicles wiring harness. I have installed other wiring harness's before so I was able to locate the appropriate wires. All is working well now. 4032

Works well. Pretty easy to install, once I'd watched a couple of the videos. I'm using it in a '05 Toyota Echo. I managed to cut the wire to my brake-lights with the splicer, (make extra sure the wire's are seate in their channels before crimping) but hey - there was an extra splicer in the pack. The quality looks good, equal to the car's wiring, and much better than the wiring for the mail-order trailer kit I'm towing. 81159

Just as easy as the hitch install, a minor glitch ensued as locating one of the circuits was a bit difficult , the online video was different than the automobile I have. Just different colored wires and a bit of ingenuity. Again my thanks for expert service with a quick telephone call to assure me. Great product as well as an easy install. My genuine thanks and my continued shopping will be with etrailer. 186087

by: Chris W. / Florida06/25/2011

Nice kit. I really liked the tester that comes with it. I would suggest a new design to accomodate getting the wires from inside the trunk to the outside. Both the adapter and the harness connector are bulky and would require a larg hole to pass through. Maybe a round multi pin connector that mounts in the trunk floor panel. Then screw the connector to it and mount the harness plug cap on the hitch frame. ??? 17944

The taillight converter works great on my 2002 VW passat wagon. Once I got it hooked up that is. The directions on etrailer were fairly easy to follow but, it would have been nice if a hard copy had been included. The only issue I had really was the green wire for the right flasher was just barely long enough. Otherwise, a pretty straightforward install only took me about an hour or so from start to finish. 102631

I was replacing a similar product produced by another company, Curt, which failed on me after only about 6 months, so the installation in my case was a little simplified. I just did the install today and it is working as it should. I do like the fact that it came with it's own tester and all the connectors. There were no instructions, however, it's pretty self explanatory as far as I'm concerned. 69664

Great kit, very easy install in a 2008 Toyota Yaris 5-door Hatchback. Love the little lead-tester, that really made life easy, as did the snap-on connectors. I was a little unsure as to whether the snap-ons would work on the relatively thin wiring in the Yaris (much thinner than what comes with the harness). It seems to have worked fine, but perhaps a different snap-on connector would be better. 38168

Right now I am only giving this a " Fairly Good" rating. It came with no directions, though it's pretty straight foward...Until it comes to splice into the vehicle wiring.I have not even looked at the light wiring yet on the vehicle I am installing this on(2010 Volkswagen New Beetle) but I do not know if the wiring in the beetle is color matched to the wiring in this kit. Shipping was super fast . 34643

The wiring kit worked as described. The wire that runs to the right side of the car is a bit short to route it correctly (completely hidden behind trim panels). I also don't personally use the suitcase connectors supplied but they will probably suffice in interior installations like this. Not a big deal to lengthen the green wire by a foot or so but it would have been nice if it were longer. 187224

Ordering was easy and efficient. Product arrived in two days and e mails kept me informed of progress. Video on website was great in providing directions on installation. Installation on my Land Rover Discovery was simple and took about an hour. All in all a very good experience. Having the tester as part of the package made checking out the system very easy. We appreciate it very much. 22298

The hitch it self was excellent and the service was real good. The wiring kit came with no directions. The stuff online for it was not that good. It all did work out well but it took time and the weather was not nice. It should have said universal wiring and I would not cared. Next time I'll be more careful. This is a good company to deal with. This is the first complaint I've ever had. 366250

Great service! My order was placed late in the afternoon. Then, after I received the automatic confirmation, I got a PERSONAL email from the shipping department - stating that they woule be able to get my order shipped THE SAME DAY! Just a few days later, I received my merchandise in a carefully packaged box. I am a repeat customer - and a raving fan. does it right! 3804

Hitch was excellent. Straight out of the box, it bolted directly on the car without any modification. The wire harness was another story. The wires on the vehicle are super fine and the T-connectors cut them so I needed to get creative with the wire connections. Other than that, I would recommend to everyone that "" delivers exactly what I ordered in a timely manner. 30311

Works great and as advertised. Watch an online tutorial to simplify the process. On my Avalon, the easiest way was to not probe the wires but disconnect the connector in the vehicle wiring harness close to the left tail light, inside the trunk under the carpeted trim and do the circuit testing from there. Tester comes with the converter, along with instructions. 17655

Product was perfect and very easy to install. The tester that came with it was amazing and all the lights work perfectly. I couldn't be happier with this product...I have never done anything like this before and it took me 20 mins to install and connect the wires which were labeled very clearly. Any needs for my trailer I will be coming here without a doubt 50346

Trailer Wiring Converter Very good product and easy to install. However there were not printed installation instructions. The website provided a video that fully explained the process but there should be something to direct the user to the site. The installlation went just like the online video and had the install complete in about half an hour. Steve 4866

  • Location of Brake Control Connector on 2006 Dodge Ram 2500
  • If your Ram is equipped with the tow package including the 7-way trailer connector on the rear bumper, the connector for installing your brake controller will be located above the white junction box behind and a bit above the emergency brake pedal. The connector is usually light blue in color. If the plug is present, you'd need the # HM47755 brake controller wiring to install the Hopkins Agility brake controller in your Ram.

  • Can a 3-Wire to 2-Wire Trailer Wiring Harness Converter be Bypassed
  • The only way to bypass a 3-wire to 2-wire trailer wiring harness converter (assuming your vehicle has a 3-wire or separate tail light system) would be to convert your trailer to a 3-wire (or separate) tail light system. This means you will need a separate tail light circuit, brake light circuit, and turn signal circuits on the trailer. You will also need to use either a 5-way, 6-way or 7-way style trailer connector on your trailer and tow vehicle and substitute one of the pins for the additional...

It will be taped to another harness near the emergency brake pedal. See the picture to the right that will show the location.

If your motorcycle has the brake light circuit connected to the extra circuit you will need to do some re wiring or install a converter, item # 119178KIT, on the motorcycle.

  • Parts Needed for Setting up a 2003 Dodge Ram 1500 For a Trailer with Electric Brakes
  • If your 2003 Dodge Ram 1500 came with a 7-Way trailer connector from the factory it is pre-wired for a brake controller. If this is the case, all you would need is a brake controller and the wiring harness to plug the controller into the port under the dash. Our most popular brake controller is the Tekonsha Prodigy P2 # 90885. It is a pretty easy controller to use and is quite effective.

  • Troubleshooting Trailer Turn Signals Both Flashing With Brakes or Running Lights On
  • It sounds like there is a ground issue in the wiring, probably on the trailer side, but it will be a good idea to check all of the grounds to make sure. Start with the white ground wire from the converter box of # 119178KIT. Make sure it is attached to a clean and corrosion free bare metal surface on the vehicle. Next, check for any dirt or corrosion in the vehicle and trailer side connectors. You can then move on to the trailer side. Check the main ground coming from the trailer side...

  • How to Bypass the TIPM of a 2006 Dodge Ram and Install a 7-Way Trailer Connector
  • The TIPM of your 2006 Dodge Ram can be frustrating to deal with in terms of trailer wiring. When you short out the TIPM you have to take it to a dealer so that they can reset it, and they will only do this so many times before you have to spend a ton of money to replace it.
