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.

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

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

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
The wiring kit made it easy to correctly install "the first time"! 112711

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
Quick shipping! Helpful customer service rep on the phone. Installed everything myself (lucky me I had an auto lift to use), bought a 4x8 flatbed trailer on craigslist, and pulled a piano, desk and other furniture about 250 miles with my 1997 Toyota Corolla. Thanks a bunch for the great product! 107136

I have a 1996 Toyota Avalon with 243,000 miles on it. It still runs like new, so I wanted to continue to use it with my utility trailer. Enter e-trailer.com. Wonderful product. 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

I ordered a trailer wiring conversion connector from e-trailer. The product was shipped quickly and the installation was well explained in the online instructions; although I think it would be great if written instructions were sent with the order. I would recommend e-trailer and will order from them next time. 109972

This product was installed under an hour. Had a minor glitch where the left turn signal was flashing rapidly. After checking my connections again I found that the left turn signal wiring had actually been spliced in half not completing the circuit. Re spliced works great! Thanks 119706
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

I installed the 2" hitch and wiring kit on my 2003 Ford Crown Vic. Very easy and I think it looks Great. Thank you for making it a easy complete package. I watched the YouTube video on how to install the wiring kit It only took maybe 30 Minutes . 152251
by: Shelton H.11/12/2014
Works fine , a little work to install. 160644
Followed the instructions, actually my wife read them to me as I was in the trunk connecting the wires, and had the wiring kit 119178KIT installed in about 45 minutes…or less. Worked as advertised for my 2002 Buick Park Ave. 124951
installation was a breeze. used the youtube video on the page which was fantastic. Anyone can do it. the only tool you need is a pair of pliers. Might recommend including a couple zip ties to manage the wires. great product. 128173
by: Brett Baker04/24/2014
The service was excellent and the delivery time was exceptionally fast. The wireing kit did not specify that it needed to be wired in instead of just the easy plug in type. Great product very easy to install. Thank you. 127242
by: Corey J02/04/2015
Great kit! Like others, I wish a simple instruction sheet would have been supplied. The back of the unit didn't have double sided adhesive on it like it shows in some video too. 172376
by: Robert S07/05/2013
No problems at all with the product, however, wiring instructions would have been nice! What could have been an hour long job turned into several. 87794

Great wiring harness and after watching your video I installed it in about an hour! 132373
Installment of the wiring kit was a real pain without detailed instructions. 89973
I thought it was a plug-in and use. Little more work but that's OK. Thanks 104200
Everything worked well , no problems with install. 121283
