Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring - no cutting, splicing or tapping required. Includes tail light converter.
Features:
Specs:
Installation
This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness.
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.
Tail Light Converter
A tail light converter is built into this T-One connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of your trailer. The tail light converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.

No cutting,no splicing!! Just great!!!! Installed on 2003 Mazda Tribute
Very easy to install. The Video shows how easy. No cut wires! Fits over factory wires! A++++
Instructions were very vague, would have had difficulty if I had not viewed the U tube video.
The product was exactly what i needed at a reasonable price and recieved it really fast
thanks Ryan
Great product pretty quick install. The directions are poor and need more pictures or better literature.
Very happy with product.I was suprised when it showed up earlier than expected.worked out great was able 2 work on it on the weekend.thank you so much 4 your prompt service.
How easier could it be. So simple I was done in 15 minutes and plugging in the trailer to check it out.
Great product and so easy to install if you throw the directions in the trash immediately. The video shows you exactly what to do and where everything goes step by step so you'll be done in no time.
This product was an EXACT match for my vehicle and installed just as easily as stated. In fact I was able to instal it in the same amount of time it took to watch the "how-to" video on the product page.
Great product. The video instructions were very clear. The installation was even easier than the video led me to believe.
Works GreatFast Shipping. Easy Installation. Works Great. Video made it very easy to connect. No splicing. Everything fit exactly.
The wiring harness works great. The instructions that came with it, however, are worthless. The only correct part of the instructions is knowing the passenger side from the driver side. Use the video on etrailer.com. There is also a text of the video instructions. If not for the video, it would have taken twice as long to figure it out.
Easy Installation. The video guide on this website made the installation a breeze. It took me no less than five minutes, and now with this wiring harness I Installed my tailgate light bar. This is a perfect product for any use.
Got the trailer wiring harness (Part # 118343) for my 2001 Escape. I watched the video, and installation was very easy. The hardest part was getting the tail lights off. Less than an hour of work and I had a great trailer hook up with no wire splicing. Now...its off to the lake with my little boat to catch some fish. Thanks for the prompt shipping and email order and shipping updates. Its ncie to do business with a company that keeps their customers updated on their order. I'll be ordering more from etrailer.com.
I bought a used van that had some electrical issues with the factory trailer wiring. When I came across the installation video for this product, I quickly ordered it. Once I got the item, it was VERY easy to install and works like a million bucks!
No more trailer lighting worries!
The wiring set I got here works perfect long term. I pull my work trailer 24/7.. I think I did have to pay attention while installing it but it works. I had to buy this because the wiring on my car and the wiring on a trailer are different. and this was the solution.
Plug and play - thank you for the step by step install video.
Excellent product. Exact fit. Pre drilled holes made it easy for this 67 year old woman to install. Good quality. I also ordered the light kit for my 2003 Ford Escape. Easy to install with provided instructions.
Great product, fits well on my 2001 Ford Escape. If I'm need another I will purchase from etrailer Corp again. I'll recommend this product to anyone who is in need of this product. Was very easy to install, great for my hauling, help me to move items with ease with my pull behind trailer.

Product is still great, no issues with hauling. I absolutely love it.
I am very pleased with the Curt Trailer Hitch Receiver and the ball mount I ordered . I use my trailer frequently to haul lumber, fencing, and riding lawnmower, the product is of good quality and I recommend etrailer
Thank you for quick shipping & a fantastic product! Exactly what I needed to complete my trailer hookup!
Ordered this hitch for my 2003 ford Escape. Placed order Sunday eve standard shipping and received wed. Very happy with the product. Drove the rear wheels up on ramps and installed in about 35 min. Slightly difficult by myself but is possible if you hold one side with you foot! I ordered the bolt guide wire which was to lose but twisted it to tighten the spring end so there was no chance of the carriage bolt getting stuck. The wiring loom was plug and play. Whole install hitch and wiring took 1 hour with the help of you tube video.
Product works and was easy to install with a video guide. Written instructions were extremely confusing. I'm not sure what to do with the grounding wire though,because my 03 Escape did not have a predrilled hole for it...?

Thank you for your review! You can just use the metal screw that came with the kit to attach the ground into the sheet metal behind the taillight.
I was surprised how easy it was to install the trailer hitch and the wiring harness.
It has worked great and saved me over $150. The pictures really helped.
Mazda Tribute 2002 LX. Excellent product. I watch the installation video which was a big help. No need to get under the vehicle and get dirty. All T connectors were exact fit. My panel where the trailer connection comes through was a little different. Still, I just used my 1/2 drill bit and made 4-5 holes and made an oval for the connector to feed through. I used some black tape to repair the cut you need to make in the grommet for the new cable. For the right side, flat cable I made a "T" cut into the grommet. This allowed the grommet to close around the new cable more naturally and helped with the taping. Used it last weekend, worked like a camp!
