Tow Ready Wiring - 119178KIT

Tow Ready Circuit Protected Taillight Converter with 4-Flat End by Draw-Tite, Hidden Hitch and Reese

Adapts import and domestic automobiles with separate turn and stop lights (3-Wire System) to standard trailer taillight wiring (2-Wire System). In a three wire system, a separate wire is used to carry each of the stop, turn, and running light functions to the taillight assembly. On most trailers, the stop and turn signal functions are sent through the same wire.

Video Transcript for TowReady Taillight Converter Hardwire Kit Installation - 2001 Chrysler Sebring

Today in our 2001 Chrysler Sebring convertible, we will be installing the tow-ready, upgraded circuit-protector tail light converter hardware kit with four-pole end, including a tester, part number119178KIT.To begin with here, we're going to figure out whether we have a two-wire or three-wire system on this vehicle. We'll go ahead and run through the light functions and see which bulbs come on when we turn the running lights on, the blinkers, as well as the brake lights. As you can see here with the running lights on, we get the top two bulbs, which are red here, come on on both sides. When you step on the brakes, just the two inner bulbs towards the center of the trunk come on. When we turn each blinker on, it's actually a bulb down below that's part of the clear section. With running this simple test, this tells us that we have a three wire system, so we will be using the red wire on the converter box. We will be connecting this red wire to the brake light wire. Now, let's go ahead and open up the trunk, and we'll go ahead and figure out which wires do which on the back side. We'll begin here on the driver's side. We'll go ahead and just simply peel back the inner lining of the trunk and it will expose the back of the tail light assembly, where we'll simply slide the red locking tab over and unplug the wiring harness from the back of the light assembly.

Once we have the wiring harness removed from the back of the tail light assembly, now we'll go ahead and use our test light to figure out which wire is the running light circuit. To do this, we'll need to make sure that our running lights are turned on. We've found that the black wire with the yellow stripe is the running light circuit, the green wire is the blinker, and the white wire with the orange stripe is the brake wire. Again, we'll be using the yellow wire from the harness to the green wire, which is the blinker wire on the factory harness. Again, all these connections will use our quick-splice connectors supplied with the kit. You simply slide the two wires in, take a pair of pliers and squeeze down. When doing this, it actually pierces both wires, making the connection.Then you simply fold the top of the quick-splice connector over and you're done.Now since we know that the brake wire is the white wire with the orange stripe, and this is a three-wire system, we'll have to connect the red wire to the white wire with the orange stripe. Now,we'll also need to go ahead and mount this converter box over here on the driver's side. We'll do this by using the two-sided tape supplied with the kit. Now that we know which wires we are going to be connecting into on the driver side, we're going to go ahead and plug this plug back into the back of the tail light assembly and put the locking tab back in place as well. Now that we've traced our wires over, we see that the wires actually run from the driver's side over to the passenger's side tail light.

Now that we know where the wires run, we'll go ahead and peel back the carpet on the inside of the passenger's side, unplug the light over here because we need to figure out which is the turn signal wire over here on the passenger's side. Using our test light again with the blinker on, we found that the brown wire is the blinker wire over here on the passenger side.On this side we will be connecting our green wire off the converter box. Now because the wires run over from the driver's side over to the passenger side inside the trunk, we're going to actually make our connection over closer to the driver's side, just so we don't have that wire running across the back side of the trunk. We'll go ahead and snip off the excess green wire when making this connection. Now that we have got all our driver's side connections made, as well as our ground screw in place, we'll go ahead and connect the wire for the passenger's side. Now that we have all the connections made over here for the driver's side, we're going to use a little electrical tape to secure up any excess wire. We'll also need to put our ground in, which is the white wire with the ring terminal already connected. To do this, we're going to use a self-tapping screw and screw into an area of the body that'salready doubled up with sheet metal. Now for the self-tapping screw, we'll be using part number FA1131822. You also want to make sure that when putting the ground screw in that there's nothing behind it that could be damaged and put any other parts of the interior trunk that we may have removed back in place, as well as making sure both the tail light plugs are back firmly in place and the locks are locked. Now when using our four flat on this particular vehicle, you need to make sure you stay away from the center trunk latch area so the wire is not damaged when you close the trunk. You simply want to put it off to the side and close the trunk on it.The weather stripping on the trunk will allow the wire to come out the rear of the trunk and not be damaged when the trunk lid is closed. We can go ahead and test our four flat. To do this, we can use our test light and have someone run through the lighting functions.We'll take the ground off the test light and connect it to the open prong on the four flat. This open prong is actually the white wire on the four flat. With the running lights on, we'll touch the brown wire.The brown wire is the running lights. As you can see, you get a constant light or a beep.

For the left turn signal, or driver's side, you'll touch the yellow wire.You should get an intermittent beep or flash for the turn signal. For the passenger side, or the right side, you'll touch the green wire,again an intermittent beep or flash for the turn. For the brakes, it will be a constant light or beep for both the yellow and the green wire. As you can see here, everything is working just fine. When not using your four flat, you can simply stow it away in the trunk area of the vehicle. With that, we will conclude our installation of the tow-ready, upgraded,circuit-protected tail light converter hard-wire kit with four-pole end including the tester,part number 119178KIT on our 2001 Chrysler Sebring convertible.

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.

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.

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

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

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 was shipped fast, delivered at my door, and everything was there. Now, while I could not install it myself, my mechanic said it was so easy and a perfect fit. I highly recommend etrailer.com to anyone. Excellent product and company Try it!!!! 99864

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

Installed on 2007 Honda Civic Si. I have after market exhaust so it was a much tighter fit. Instructions were easy to follow, I also purchased the upgraded trailer wiring kit. I work with electronics so it took less than 20min to install. Over all great product, strongly recommend a second set of hands to make install even easier. 92071

Great product, fast shipping. Although, it did not ship with any instructions or diagrams. I needed to go on the web and watch a video of the unit being installed on a different vehicle to determine what each wire color represented. Other than that, 100% satisfied. 153889

  • If your 2008 Toyota 4Runner came with a factory 7-Way trailer connector, all you will need to connect the Tekonsha Voyager Brake Controller, # 39510, is to use harness # 3040-P. The port on the vehicle side should be located under the dash. I have included a link to a video showing installation on a similar vehicle for reference. If the vehicle did not come with a trailer connector, you will need to first install a 4-Way, # 119178KIT, and then a 7 and 4 Way Installation Kit, # ETBC7....

  • Recommended Receiver Hitch and Trailer Wiring Harness for 2007 Ford E350 Van
  • The highest rated hitch available for your 2007 E350 would have a 10000 lb towing capacity. With the use of a weight distribution system, the capacity can be increased to 12000 lbs. I would recommend the Curt Class IV Receiver, part # 14055, which will use existing holes in the van frame. We offer the wiring harness with trailer connector, draw bar and trailer balls to complete your towing system, but they are not sold as part of a package. I would recommend the following: Wiring...

  • Trailer Wiring Harness for 2006 Honda Element
  • For your 2006 Element, you will need to use a hardwired converter, like part # 119178KIT. The converter will tap into the factory wiring harnesses feeding your taillight assemblies. The best place to tap the wiring in would be directly behind the tail light assemblies. You would use the circuit tester included with the kit to probe the wires feeding each taillight assembly to determine which wire carries which circuit. Activate the left turn signal, and then probe the wires feeding...

  • Brake Controller Installation from Scratch on a 2001 Land Rover Discovery II
  • We do not currently carry a wiring harness for your 2001 Land Rover Discovery, so you will need to hard wire your vehicle. You will need three components. First, a brake controller.

Last, you will need a 4-Pole trailer connector like Upgraded Circuit Protected Taillight Converter Hardwire Kit with...

  • Trailer Hitch and Custom Trailer Wiring for a 2008 Dodge Ram Quad Cab 1500 Big Horn
  • The 7-Way and 4-Way Replacement Connector, # 42145, is the correct harness for your 2008 Dodge Ram if you already have or had a factory 7-Way. One end mounts to the rear of the vehicle, there might even be a knock out on the bumper that can be removed. The other end plugs into the vehicle wiring. Your truck should have a plug behind the bumper, near the center. It will plug into the square connector of the harness. If the truck does not already have any connectors, you will need to start...

  • Installing Aftermarket Trailer Brake Controller, 2010 Dodge Ram 3500 with Factory Brake Controller
  • I spoke with my contact at Tekonsha about installing an aftermarket brake controller on a 2010 Dodge Ram 3500 with factory installed brake controller. He stated that you will get that error message and you will not be able to clear it. It is indicating that something is wrong with the factory unit and will remain as long as the factory unit is disconnected. It will not impact an aftermarket brake controller when installed, the aftermarket unit should still work properly. Since there...

  • Installing Brake Controller on a 2007 International 4400 Truck
  • Since there isn't an adapter to go from a semi 7-Way to an RV 7-Way the best solution is going to be to install a separate RV style 7-Way on your 2007 International 4400. You can use installation kit # ETBC7. You may be able to tap into the circuits on the existing 7-Way as long as the turn signals and brake lights are combined on the same circuit. If not them you will have to first install a 4-Way using # 119178KIT. If the circuits are combined on the existing semi 7-Way then all...

  • 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...

  • If your Land Rover came equipped with a factory installed tow package, you can choose a brake controller, like the P3 brake controller, # 90195, and then contact your dealer about where and how it would connect under the dash. If you don't have the tow package, you would need the controller and the Electric Brake Controller Installation Kit, # ETBC7, along with a working 4-way connector, # 119178KIT if needed, at the rear of your Discovery. We have detailed instructions, see link, for...

  • 4-Way Trailer Connector Wiring Harness for a 2002 Nissan Xterra
  • For your 2002 Nissan Xterra, you will only need a 4-Way for brake, turn, and running light functions. A 5-pole would add reverse lights which are not legally required on a trailer. The best thing to do is to get the plug and adapter (if needed) that matches your trailer. What you will need for the basic brake, turn, and running lights is Draw-Tite Wiring, # 119178KIT. This converts a 3-wire system (vehicles with separate turn and stop lights) to a basic 2-wire system which is the standard...

  • Is a Class I Hitch for a 2002 Mazda Protege5 Safe to Tow a Trailer with Cargo Weighing 1,400 Pounds
  • The 2002 Mazda Protege5 is a smaller car, but it can still tow. You will want to check the vehicle owners manual to determine the towing capacity of the vehicle and make sure that you do not exceed it. If the hitch is rated higher or lower, you will still need to go by the lowest rated component in the system whether it be the hitch or car. There are only Class I trailer hitches available for your vehicle. As you have stated, the gross trailer weight capacity of the Hidden Hitch Trailer...

  • Installing a 7-Way Trailer Wiring Harness on a 2003 Dodge Ram 1500
  • First, I would be certain that your 2003 Dodge Ram 1500 uses a 24 system. If you have 2 batteries and the positive of one is connected to the negative of the other, then it is a 24 volt system. But if the positive of one is connected to the positive of the other (and the same for the negatives) then you have a 12 volt system. If you do have a 24 volt system what you would need to do to get power to the 7-Way would be to splice in a wire to the cable that goes from the positive of one...

  • Troubleshooting Trailer Tail Light Circuit on 2005 Toyota 4Runner
  • I do not have any specific information about what color wire feeds the running light circuit to your OEM 7-way on your 2005 4Runner. Vehicle manufacturers have been known to vary wire color within the same model year, so wiring by color does not always work. If you can access the rear of the connector, and find the terminals where the individual wires attach, the wire that feeds the pin in the 1:00 position will be the running light circuit. I have linked you to our Wiring FAQ article...

  • Adding a 7-Way Trailer Connector to a 2012 Dodge Ram 2500 Big Horn With Flatbed
  • If your 2012 Dodge Ram 2500 came with a factory tow package that included a 7-Way at the back of the vehicle, you can use 5th wheel and gooseneck in-bed wiring harness, # 51-97-410. This harness plugs in line with the factory wiring harness under the truck and provides a 7-Way in the bed area. If the truck did not come with a factory tow package that included a trailer connector, you will have to hardwire one in starting with a 4-Way using # 119178KIT. A T-connector is not available....

  • Recommended Wiring for the Pilot Brake and Tail Light Trailer Hitch Receiver Cover # CR-007A
  • Pilot does not offer a wiring diagram for the Brake and Tail Light Trailer Hitch Receiver Cover, # CR-007A, but the wiring is pretty simple. The hitch cover has a 4-way flat connector that was designed to work with typical 2-wire systems, meaning the brake light and turn signals are combined on the same circuit. The hitch cover has a converter to prevent the turn signal function from reaching the light. In other words, the turn signal function will be reaching the hitch cover connector,...
