Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located beneath the rear of your vehicle, on both the driver's side and passenger's side. You will find the harness behind protective covers near the rear bumper.


Once installation is complete, the 4-way flat connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

I only wish all companies operated as efficiently, professionally and quickly as Etrailer. They have what you need at the right price and their website is simple to navigate. After placing my order I received emails which seemed very one on one updating me regarding my order. I will order from them again as well as tell friends about them. Thank you.

Easiest light wiring ever.I've wired a lot of trailer light plugs in my time, but this was without a doubt the easiest I have ever done; once it was plugged in it was ready to go. And the shipping time was awesome.

I had priced a few businesses about installing this wiring harness for my trailer on my 92 Jeep and the cheapest one was over $100. I found etrailer online and found the harness for $24.99 and it was here in three days and took about 15 minutes to install myself with very easy instructions to follow and works perfectly. Thanks etrailer for saving me cash and making my experience a great one!!!

Finally got the chance to install the wiring harness . As I had pulled the wheel well covers for under carriage restoration it made the installation easier . The Bumper will be ordered soon & there is plenty of slack for connection .
Great purchase . This was installed on a 1997 Sport Wrangler .

Purchased the 2 part trailer stainless steel bumper with trailer bracket . installed wiring and tried out . Everything works fine ..... would recommend



by:

Both the hitch and the wiring harness arrived with the packaging beaten up and gouged out . Also one of the mounting holes on the plate to attach the hitch does not match up with one of my holes on my Jeep. I have to drill it out to use the hole on the hitch mounting bracket.

Hey William! It sounds like your hitch is flexed from the rough shipping. This happens frequently enough that we actually have an article about how to bend it back to shape. I linked that for you. Dont be too intimidated - its easier than you might think! Also, if you are missing any pieces, please let us know so we can ship you some replacements.

Good communication, avg. price, fast shipping. Installed quickly just as described. Seems like quality product.

1992 Jeep YJ

Amazingly easy kit to install. I spent about an hour installing because I was meticulous about the cable management, yet if you didn't care this could easily take less than 10 minutes. The only possible thing you could mess up on is left and right plugs but even then they're labeled on the wire. Definitely worth the money, and saved all the hassle of heat shrink and soldering cables. The main pro here in my eyes though is the fact that this kit uses connectors, which leaves the wires very well protected compared to others which have you splice.

  • Flat Towing Wiring Kit for a 1997 Jeep Wrangler TJ
    To power the lights on your 1997 Jeep Wrangler TJ while flat towing I recommend the Roadmaster 4-Diode Universal Wiring Kit for Towed Vehicles - 7-Way to 6-Wire Hybrid Cord item # RM-152-1676-7. This complete kit includes everything you need to connect your RV's tail, brake, and turn signal lights to your Jeep. The diodes prevent feedback and wire your Jeep and RV to operate as a combined system. I have linked our options of base plate kits for your 1997 Jeep Wrangler.

  • Trailer Wiring Harness for a 1989 Jeep Wrangler (YJ)
    If you bought wiring harness # 118356 then that would be the problem. This harness does not fit a 1989 Jeep Wrangler/YJ. The only trailer wiring harnesses we have listed for the YJ are hardwire harnesses, # 18252 or # C58044. If you bought a different harness let me know what it is and I can determine what it fits since there are no T-connectors for your YJ.

  • Recommended Trailer Hitch For A 1994 Jeep YJ For Dirt Bike Carrier
    I recommend the etrailer Trailer Hitch Receiver # e98859 for your 1994 Jeep YJ. I like this hitch because once the hitch is installed it has a hidden design. The hitch has a bolt-on installation. The hitch also has a matte black powder coated finish that will help keep scratches and scuffs that you get while towing less visible. To carry your dirt bike I recommend the Ultra-Fab Dirt Bike Carrier # UF48-979033. The trailer hitch has a loaded tongue weight of 350 pounds, so depending on...

  • Towing a Boat with 1997 Jeep Wrangler TJ
    After doing a little bit of research I was able to determine the maximum tongue weight of your 1997 Jeep Wrangler TJ is 300lbs and your maximum towing capacity is 2000lbs. So given the parameters that you're describing, you should be able to tow a small boat in your TJ. In case you don't already have a hitch you may want to look at the Curt Class III Receiver # 13430 , which is sized to fit your Jeep. To go along with the hitch you need the trailer wiring # 118356 and a ball mount. The...

  • Recommended Trailer Hitch for 1992 Jeep Wrangler YJ
    I know exactly what you need! I recommend using the etrailer Trailer Hitch Receiver - Custom Fit - Matte Black Finish - Class III - 2" which has a durable matte black powder coating that will hide nicks, dirt and blemishes much better than the glossy black finish that some other hitches have. This hitch has a 2" receiver and will mount to the rear of your YJ without any drilling required. If you need to also replace your trailer wiring harness on your 1992 YJ, I recommend using the Tekonsha...

  • Can a 350 Pound Motorcycle be Carried on the Back of a 1995 Jeep Wrangler
    Curt trailer hitch # 13657 for your 1995 Jeep Wrangler (YJ) has a tongue weight capacity of 350 pounds. The capacity only goes up to 400 pounds when towing a trailer and using weight distribution. So for hitch mounted accessories the hitch tongue weight capacity of 350 pounds it what you will need to go by. If the combined weight of the bike and carrier is over 350 pounds then you will not be able to carry the bike on the Jeep with a hitch mounted carrier. You would instead need to put...

  • Is it Possible to Tow With 1-5/8
    The best solution for you is going to be simply replacing that hitch with a new one, the Curt # 13657, which is a fit for '92 YJ's with the exception of Renegade models. The Curt is a Class III hitch that has a towing capacity of 3,500 lbs, tongue weight capacity of 350 lbs, and more importantly, a 2" receiver opening. To complete your towing setup you would want a 4-flat trailer connector # 118356, ball mount # C45030, 2" hitch ball # 63845 and pin and clip # C21500. I've added links...

  • Correct Trailer Wiring for a 1997 Jeep Wrangler
    I understand it can seem confusing but there is an easy solution. Very Easy! If you use the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118356 it will simply plug into the plugs beside each tail light. It will then send the signal to the 4 way trailer connector that you will hook the trailer to. The reason it works is because your Jeep is telling the wiring what to do.

It comes with diodes that will protect both vehicles wiring systems by preventing feedback.

  • Installing a 4-Way Trailer Connector on a 1988 Jeep Wrangler
    The T-One wiring harness, part # 118356, is designed to fit newer Jeep Wranglers starting in 1991 but is not a confirmed fit on your 1988. The wiring harness for your Jeep is a hardwire and I recommend using part # 18252. It includes a circuit tester to find the correct circuits on the Jeep, as well as quick splice connectors to make splicing in a lot easier. I've linked a video of the harness being installed on a 1985 Monte Carlo SS (Because why not, right?) so you can see the process...

Temporarily remove each of the protective covers under the vehicle next to the rear bumper.

  • Curt or Tow Ready Trailer Wiring Harness Recommendation for 1995 Jeep Wrangler
    The two harnesses you mentioned part # C55356 and # 118356 are both a fit for your 1995 Jeep Wrangler. Essentially they are the same harness made by two different companies. If it were me I would go wit the Tow Ready # 118356 as it has a better price and in general we see the Tow Ready harnesses as being the most reliable. I attached an install video that shows the harness being installed on a 1995 Jeep Wrangler just like yours.

  • Availability of Trailer Wiring Harness for a 1997 Jeep Wrangler TJ

In 1998 the wiring for the TJ changed a bit and the Wiring harness was then changed to work and given part # 118409. To install a 4-Way wiring harness on your 1997 TJ you will need to use item # 118356. I checked fit with 3 different manufacturers and all of their wiring harnesses change between model year 1997 and 1998. I am including a link to the installation...

  • Parts Needed to Install 7-Way 1997 Jeep Wrangler for Towing Surge Brake Trailer with 7-Way
    First you need to start with a 4-way connector if you do not have one already on your 1997 Jeep Wrangler. For that you would want the part # 118356. Then to convert this to a 7-way to match your trailer you need the part # 37185. The purple wire of this kit needs to be connected to your reverse light circuit and you will be set. You would want to use a quick splice like part # SWC501746-1 to tap into the reverse light circuit.

  • Trailer Hitch Recommendation for 1993 Jeep Wrangler YJ
    For a hitch for your 1993 Jeep Wrangler I would recommend the etrailer hitch # e98859 as it has great towing capacities and an easy install. With that said Adam there just isn't going to be a way to use a carrier for the motorcycle as your Jeep can't handle that amount of weight. The best solution would be to tow a small trailer with the hitch I mentioned. If you need trailer wiring too you'd want the Tekonsha part # 118356 which installs easily.

We hear about less issues with the Tekonsha harnesses, in this case # 118356, so if it were me that is the one I would go with. It will provide the basic light functions for a trailer.

  • Converting European 7-Way Wiring Harness on 1997 Jeep Wrangler Back to US 4-Way Wiring Harness
    On a European 7-Way trailer connector, the connector is pinned out differently than those used in the United States. They also use more wires to cover the same functions as a US wiring configuration. I would not have an adapter that could be used to adapt your European 7-Way connector to a US 4-Way connector. It would be much more beneficial to wire the trailer to work with a US configuration and to replace the wiring harness on your 1997 Jeep Wrangler back to US specs. When you rewire...
