Video Transcript for Tow Ready Wiring 119179KIT Review

Today we're going to be taking at look at the Tow Ready upgraded circuit protected ModuLite with the four pole harness and hard wire kit. This unit is going to provide a four way flat trailer connector at the back of your vehicle to power your trailer signal lights, and it's going to include everything that you need for a full installation. It's going to offer short circuit protection which is going to safeguard itself and the tow vehicle against harmful electrical shorts and miswire situations. It's going to virtually eliminate draw on the vehicle tail light circuit, so that's a great advantage to have with this system. The tail light circuit on this unit has been upgraded to work with vehicles using PWM which is pulse width modulation, allowing the converter to turn on fully giving the trailer maximum light brightness. This unit's going to power the trailer stop, turn, tail and running lights directory from the tow vehicle battery. It's going to prevent feedback from trailer to vehicle systems.

It can be used on two and three wire systems. Just keep in mind when used on a two wire system, the thin red wire which is going to be your brake wire, must be grounded. It's going to adapt a three wire system on the towing vehicle to a two wire system on your trailer. It will work on vehicle and trailers with either LED's, incandescent or standard bulb tail lights. It's also going to work with most vehicles that use a multiplex wiring system for lighting. Again, we're going to go over the components that it all includes.

When using this system, you're going to have a maximum amperage of 2.1 amps per side for the stop and turn lights and 5.6 amps for the tail lights. Included with the kit, you're going to get your four way connector. You can see we've got the wire bundled up here so that way you can extend the amount that you need out the back of your vehicle to make your connection to power your trailer signal lights. It's going to have the dust cap. That way we can protect the connection points when the connector is not being used. We can cover those up and that's going to help prevent any type of corrosion from settling into our connection terminals. The black box is going to be a converter box.

This is simply going to help avoid overloading the vehicle's electrical system. Then on this side, you're going to have all your wires. Your green wire is going to be for the passenger side turn signal. Your yellow wire is going to be for the driver's side turn signal. Your brown wire is going to be for your running lights.

The thin red wire is going to be for the brakes. The white wire with the ring terminal attached to it, this is going to be for your ground connection. Some vehicles that this unit will work with is going to have a grounding post in which you can slide this over the post and reinstall the hardware to make the ground connection. Some vehicles with not have that post. They include a self tapping screw so you can make that connection to a nice clean, metal surface. Then you're going to have your thick red wire. This is going to be your 12 volt power wire. It's going to connect to the bundled black wire here. This is going to be 20 feet of 12 gauge wiring. This is going to be the power wire that runs all the way to the vehicle battery. So the red wire is going to connect to the black wire using the included butt connector. It's also going to include a heat strength butt connector. Then you're going to have your fuse holder. Fuse holders are going to get cut right here in the middle. One end is going to connect to the other end of the black wire with the other butt connector. The other end of the wire is going to get one of the two ring terminals attached to it. That's going to connect to the positive post on the vehicle's battery. You're going to have a half inch ring terminal for side terminals and you're going to have a three eighth inch ring terminal for top terminals on the battery. You pick which one works best for your particular situation. You're also going to get the included 10 amp fuse. You're going to get some double sided adhesive tape. It's going to get applied to the back of the converter box here. That way you can stick it to a nice clean surface, keep it up and out of the way. Again, two butt connectors, two ring terminals. You're going to get five quick splice wiring connectors. This makes tapping into the wires quick and easy. Very simple system to use. You're going to get your grounding, self tapping screw and you're going to get your circuit tester. This is going to help find the wire functions behind the vehicle's tail lights to ensure that you are connecting everything correctly. Really nice system. Again, it's going to come complete with everything that you need for a full installation. They're even going to include some zip ties. That way you can secure any excess or slack in your wiring for a nice, clean appearance for your installation. That's going to do it for our review of the Tow Ready upgraded circuit protected Modulite with a four pole harness and hard wire kit.

2014 Volkswagen Jetta


I bought the trailer electrical kit on the same order as a Curt hitch for my 2014 VW Jetta Wagon. Both items arrived on time packed in the same box and in good shape. I will use the hitch and light hook up to tow a small sailing dingy. I watched the install videos for both products and I found them very accurate as well as helpful. The hitch was installed as planned in about an hour. The light hook up took a little longer as I had to jack up one whole side of my car for access running a power wire up to the battery. I towed the boat to the water yesterday and all worked just fine. 129324

Harness works great! It was straight forward for anyone with any wiring knowledge. The video was helpful but would have been more helpful with an instructional sheet included. I called customer service to ask a question and they were very helpful and quick in response. Good product at a good price. 130749


Comments

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.

2013 Infiniti EX37


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

2013 Kia Soul


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


Comments

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.

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

This is a clever device that I never knew about but it isolates the trailer light load from the auto system, the auto only supplying low power signals to the trailer light controller. I suggest a bunch of YouTube viewing to see how this is installed, they are excellent. Also see your owners manual for a trailer power wire to the trunk. My Volvo has this as fuse #14, and can be traced to the right taillight area, very handy. This big (red) wire supplies the power for the "controller" to distribute correctly to the trailer plug when you signal or brake, etc. No running the new wire supplied under carpet, the car body or anywhere. It works as designed and is not hard to put in overall. 1 Hour You Tube, 1/2 hr. trunk guts removal, 15 min. detecting which wires with the little tester supplied, 1 hr. installing, 1hr. putting trunk guts back and checking all out. It's very small, didn't use the tie-wraps. 272044

1985 Mercedes 300TD


The Kit is outstanding - everything you need to install the kit is included with clear and complete instructions. This is from a complete novice in doing any car wiring. The most difficult part for me was running the wiring from rear to front in a 1985 Mercedes 300TD, there were no instructions for that vehicle BUT I really didn't expect them. Thank you for an excellent product and outstanding instructions to accompany it. 158311


Comments

Hello Sir, I know this is an older review but some sites do email a notice if someone has responded to your review but, for that, I guess I will know if, of course, you are kind enough to reply. Is your 85 300td a wagon tdt? If so, I was curious as to what you have for a hitch

For Vincent M: The tow vehicle is a 85 MB 300TD turbo diesel. I installed the tow kit recommended by etrailer. I also use a single sway bar pulling a fiberglass egg - dry weight 1500 lb.

1994 Honda Civic


I purchased this product so that I could tow a small sailboat trailer behind my '94 Civic coupe. After finalizing my order online, I realized I had made a mistake and needed to change my order. I called the customer service line and a human customer service representative resolved the issue within minutes. Service was friendly and excellent, and shipping was prompt. Since the harness fits multiple makes and models a reference manual (Haynes, Chilton, etc.) for your specific vehicle is recommended to review wiring diagrams and find suitable wire routes. Ample wire is provided, and the attachment hardware was more than sufficient to make installation clean and secure. The power module and signal wiring is invisible behind the trunk paneling, and the trailer hookup discretely tucks under the carpet when not in use. 85728

Product arrived in a timely matter, appears to be of high quality and was relatively easy to install. The inclusion of a circuit tester was a welcome feature. If the products' longevity matches its' appearance, it is an excellent buy. 120841

Volvo XC70


The hitch installation went better than could be expected. Thirty minutes or so and I had the hitch installed. The wiring kit for my 04 Volvo XC70 was a little different story. I had read that the Volvo's had a towing package connector near the spare tire. I found it but was curious about what pin went where, A check of the web revealed that all the wire signals were there and already were buffered with relays and fused. I thought long and hard about using the wiring kit but decided to use it anyway. Once I had all the wiring figured out the rest was easy. The customer service person (Rebecca) really knew her stuff and was great to work with. The shipping was fast and it met all my expectations. You can't go wrong with etrailer. 86760

Infiniti EX35


Product delivered very quickly, as described. I found no installation instructions included but after a call to etrailer I was directed to a link where I could print my own copy of the installation instructions. This kit was going on a Infiniti EX35. Access to the inside area behind the tail lights was a mystery and not wanting to damage or break anything in the process, I opted to have my Infiniti dealer install the after market parts. The installation took the technician around 2.5 hours, mostly to disassemble and reassemble the back of the car. The wiring part is easy. This was not cheap, but it's done and works fine. This would be a good car for etrailer to do an installation profile on for the skilled DYIer. 126836

by: Shawn S.01/01/2015


Excellent customer support. Quality of the installation video was also excellent. Regarding the product, I was a bit surprised at the wire harness length that connects to the trailer is designed to be pulled out of the back of the car and the rear hatch closed down on it (appears rinky-dink) rather than routed under the car and mounted to the hitch, but I think I will get used to it. Also, a nice touch would have been to include the grommet and clamps recommended in the video in the kit for a few more dollars. Unless you view the complete video prior to placing your order, you end up needing to improvise along the way when installing the product. 167492

2004 Buick LeSabre


My package may have been missing an instruction sheet. Nothing in the package told me which wire from the module was for left turn signal, etc. I was able to get that from watching one of the installation videos that are with the product description on the web site. My installation was probably easier than most, because my 2004 LeSabre has the battery under the back seat. The thing I like most about it is that I know whatever trailer I might hook up to, it won't blow any tow vehicle fuses. 179408

Product delivered onetime and in great shape. The "how to" videos on attaching the trailer hitch and the trailer wiring harness made for an easy install. Very thorough. Just one comment to note: the green wire going to the passenger side was about 12" short. Had to splice. That being said…very pleased with these products and the finished look. Thanks. 181815

Bought this harness along with a hitch. This wiring harness was easy to install but the instructions could have been a little clearer. The color of one wire in the harness was misstated in the instructions. Once installed, it worked perfectly and only took about an hour and a half. 83368

Please tell me how U found the wires. :- I have an 08 EX35

comment by: chris b - 06/15/2013

You will need to use the included circuit tester to probe wires and check them for functions. One person will sit in the vehicle to activate tail lights, brake pedal, and turn signals. You will use a circuit tester to pierce the wires behind the tail lights to find which wire carries which function. Check out this video on the subject.

This is a universal wiring harness and included fairly poor instructions to assist with my vehicle installation.

Ask the Experts about this Tekonsha Wiring
Do you have a question about this Wiring?


  • Troubleshooting Dim Trailer Lights and Turn Signals Blinking Together
  • It could be a bad ground. You will have to check the ground points on each of the lights and on the trailer connector. The lights usually ground through the mounting studs. If there is any dirt, corrosion, or rust it could cause a bad connection. You will also want to check where the light bracket mounts to the trailer. I have included a video below on testing for a ground. If your trailer has a large amount of lights (like running lights along the sides) then the power draw could be...

  • Troubleshooting Trailer Running Lights Staying On when Vehicle is Turned Off
  • It sounds as though there is a short or something is mis-wired. Using a circuit tester, like the Quickee # 3808, check the connection points in the vehicle side connector, to see if there is constant power on the running light circuit (brown wire on the 4-Way) when the vehicle and lights are turned off. There should be no signal when the lights are off, and a signal when they are on. If there is a signal with the lights off, then there is a problem on the vehicle side. Check to make...

  • Installing a Brake Controller on 2005 Toyota Tundra
  • The factory installed brake controller connector should be a white plug located on the left side under the drivers side dash on your 2005 Toyota Tundra Dual Cab. I have included a photo and a video that shows the location of the plug on another Toyota Tundra at the 8 second mark. This plug may not be there if your vehicle did not come with the factory tow package. The Multi-Plug, # 20137, is designed as a replacement if your vehicle came with a factory tow package that included the...

  • Brake Controller Recommendation for a 2004 Toyota Tundra with Factory Tow Package
  • Yes, the # 5100 and # 3040-P brake controller will work after the vehicle specific wiring adapter is wired to the brake controller wires and plugged in to the connector stored near the vehicles emergency brake pedal under the dash, if your Tundra has a factory installed hitch and 7-way connector. If your Tundra does not have the factory installed options the brake controller will have to be hard wired to the vehicle and you will have to run wires and install a 4-way connector, # 119179KIT...

  • Wiring a 2011 Victory Motorcycle and Trailer for Towing
  • For simplicity, I would recommend wiring the motorcycle trailer as a vehicle trailer would be. A powered converter wiring kit, like part # 119179KIT, would be connected to the motorcycle, which would provide a 4-pole trailer connector. The converter combines the brake lamp and the directional signal onto one circuit. The 4-pole connector utilizes four circuits, the white wire which is the ground, the green wire carries the right turn and brake light combined on one circuit, the yellow...

  • Trailer Hitch Recommendation for a 2007 Toyota Highlander Hybrid
  • For your 2007 Toyota Highlander Hybrid, I recommend the Draw-Tite Trailer Hitch # 75153. This is a Class III trailer hitch with a 2 inch receiver rated for 300 pounds tongue weight and 3,500 pounds gross trailer weight. I have included a link to the installation instructions and a link to a video showing a typical installation for you. If you plan on doing some towing I also recommend the etrailer Ball Mount Kit, # 989900. It comes with 2 ball mounts, 2 balls, a hitch pin with clip,...

  • Adding In-Bed 5th Wheel/Gooseneck Trailer Wiring on a 2013 Dodge Ram 3500
  • For the 2013 Dodge Ram 3500, if the truck came with a factory 7-Way trailer connector (most of them do), then there are 2 options for adding in-bed 5th wheel/gooseneck trailer wiring. First, you can use # 41157. This connector plugs in line with the factory 7-Way just behind the connector at the back of the truck. Second you can use # PK11893-11932. This harness also plugs in line with the factory connector but requires a little manual hardwiring as well. The diagram for this is on the...

  • Recommended Trailer Wiring Harness for 2001 Lexus RX300
  • If your RX300 has the factory tow package, you can use the Tow Ready # 118245 which will plug into the connector located behind the rear bumper (see linked instructions). If your RX300 does not have the tow package, the trailer connector will need to be hardwired into the existing wiring use the Tow Ready # 119179KIT. I will include a link to the general installation instructions as well as an installation video. Although the video shows the harness being installed on a different vehicle,...

  • How To Wire a Harley Ultra Classic with a 5-Pole Round and a Trailer with a 4 Pole Flat
  • I am guess that you have a connector similar to the 5-Pole round like part # PK11502. If this is the case, you have two options. You can either remove the 5-Pole round from your Harley and put a 4-Pole flat in place, or you can cut the connector of your trailer and use a 5-Pole connector for the trailer. I imagine the 5-Pole on the bike is mounted pretty well, so I would suggest replacing the trailer connector with a 5-Pole using part # PK11501. Using a circuit tester, like part # 3808,...

  • Trailer Hitch Recommendation for a 2006 Lexus GX470 to Tow ATV Trailer
  • For your 2006 Lexus GX 470 I would recommend the Hidden Hitch part # 70779. This hitch would do an excellent job of towing your ATV trailer. We only carry Class III hitches for your vehicle so you wouldn't need to worry about what Class to get for your vehicle. For more information on the differences between the hitch classifications check out the link I attached. For trailer wiring you would want the Tow Ready Harness part # 119179KIT. For ball mounts I recommend the etrailer...

  • Kayak Carrier Options for 2013 Ford Escape with Factory Crossbars and Moonroof
  • When it comes to matters of weight capacity the vehicle manufacturer always gets the final word. If Ford engineers have determined that the crossbars on the moonroof-equipped 2013 Escape have a maximum weight capacity of 45-lbs then we cannot recommend exceeding that limit by carrying two 40-50-lb kayaks. We can offer a safer solution for you if your Escape is equipped with a 2-inch hitch. We offer lightweight trailers such as the Yakima Rack and Roll Trailer # Y08106. This trailer functions...

  • Brake Controller Recommendation for a 2008 Range Rover HSE Towing a Sooner Horse Trailer.
  • If you have a factory installed 7-Way connector on the rear of your 2008 Range Rover HSE I have two options for you to add a brake controller to your vehicle. You can use the Tekonsha Prodigy RF Brake Controller, part # 90250, by attaching the brake controller to the tongue of your Sooner horse trailer and plug it into your 7-Way at the rear of the vehicle. After you follow the instructions and synchronize the hand held remote unit to the brake controller on the trailer you would be...

  • How to Wire Vehicle to Trailer Wiring On a Lexus GX 470
  • Wiring a 4-Way connector on your vehicle will require the use of a circuit tester, item # 3808, to find the correct wires to wire to the vehicle side of a trailer connector. You can check the wires going into the connectors you have mentioned with a circuit tester while you have a helper activate the turn, brake, and tail light functions in the cab of the vehicle. If these connectors do not contain the correct wires you will need to access the vehicle lighting functions at the back of the...

  • What is the Difference Between the Primus IQ Brake Controller and the Prodigy P2 Brake Controller
  • There are quite a few differences. The ones you can see easily on the outside are the display and control buttons. The P2, part # 90885, uses a rotary lever on the underside for a manual over ride where as the Primus uses the older slide design that some people have problems with the slide sticking depending on how they grip and operate the slide. The P2 has several buttons on the face for adjusting settings and navigating through the menus. The Primus IQ uses a dial and one button to...

  • Trailer Wiring Plug Location on a 1997 Subaru Legacy Wagon GT
  • If your 1997 Subaru Legacy Wagon GT is not the Outback version, then you will not actually have a plug-in point for a trailer wiring harness. Non-Outback versions of the wagon must hard wire to install a 4-Way trailer connector, using a kit like part # 119179KIT. To hard wire the kit, you would use the included circuit tester to determine which wire carries each function behind your vehicle tail lights. You will also need to run a power wire to the positive terminal on the vehicle...

  • You should not have to relocate the spare on the 158 inch wheelbase models of the 2006 Freightliner Sprinter when installing Curt trailer hitch # 14250. However, it is always a possibility there will be interference because of slight differences amongst vehicles. I have included a link to the installation instructions for you.

  • Compatibility of Magentic Towing Light that has a 4-Round Plug and RV that has 6-Round Trailer Plug
  • Since the 119176KIT (installation details linked below) gets the power for the lights directly for the vehicle battery, it does not require any power from the vehicle wiring. It only receives the signals from the vehicle wiring. However, the 119179KIT has a 4-Way flat style connector. The Roadmaster Deluxe Magnetic Tow Lights, # RM-2100, that you have referenced, uses a 4-Round type connector that is not compatible with a 4-Flat. There is no easy way to adapt the two to work together. The...

  • Choosing Correct Hitch for 2013 Mazda 3 Sedan

The Draw-Tite Class I receiver you referenced, part # 24842 will fit regardless of which taillights your vehicle uses. Grand Touring models of the Mazda 3 are equipped with LED taillights, which will make a difference if you are wanting to install a trailer wiring harness. If you do NOT have the LED lamps, you can...

I confirmed this by checking with Hidden Hitch. The Hidden Hitch that fits the older Muranos is actually part # 87486.

  • Troubleshooting Dim Trailer Lights and Running Lights and Turn Signals Blinking Together
  • This sounds like a ground problem. If it only happens when the running lights are on it indicates a ground issue. Ground problems normally show up when there is more of a load on the system. First, make sure the main ground from the trailer plug is attached to a clean and corrosion free bare metal surface. Next, go back to the lights. Most trailer lights ground through the mounting studs if there is not an obvious ground wire. In either case, the grounds have to be attached to a clean...

  • Trailer Hitch Recommendation for a 2010 Subaru Impreza Outback Sport
  • For your 2010 Subaru Impreza Outback Sport, I recommend the Curt Trailer Hitch, # C113153, that you have referenced, because it has a slightly lower install difficulty than the other available hitches. We base install difficulty on how long it takes to install a hitch and the Curt hitch is a 5 out of 10. This means for a novice it should take about 50 minutes to install the hitch. This is a Class I trailer hitch with a 1-1/4 inch receiver opening capable of 200 pounds tongue weight...

  • How to Charge a Trailer Battery While Towing a Tear Drop Trailer with a 2002 Volvo v70XC
  • If your trailer has a 7-Way connector, then it either already has electric brakes or is set up for electric brakes. Either way, you would not want to use the pin and wiring for the electric brake to charge a battery because it is too small a gauge for this application. A 7-Way connector already has a pin for a 12 volt accessory. If you are looking at the face of the trailer side 7-Way, it is in the 11 oclock position. This wire is only large enough to maintain a battery but will not charge...

I recommend going with a proportional brake controller that engages the trailer brakes in proportion to how much the truck is breaking. This will reduce wear and tear on the truck and trailer and make for safer braking situations. For a proportional controller with wiring harness, I recommend the Tekonsha...
