Tekonsha Custom Fit Vehicle Wiring - 118343

  • Custom Fit
  • 4 Flat
  • Trailer Hitch Wiring
  • Tekonsha
  • Converter

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:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points behind tail lights
    • Plug in T-connector
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
  • Constructed of 16-gauge bonded wire

Specs:

  • Maximum amperage:
    • Stop/turn lights: 2.1 amps per circuit
    • Tail lights: 4 amps per circuit
  • 1-Year limited warranty


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.


T-One Connection Location Points Behind Tail Lights

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.

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



by:

Pricey shipping(did 2day cause of time crunch, relocating across country on the 1st). Tracking was on point. Efficient, and the product had all the necessary items for me to complete the job. YouTube video also synced up to exactly what was provided. Couldn’t be happier. All auto shops and uhauls in my area were quoting 10days to two weeks to get me in to install part number 118343, ordered the 25th, received the 27th, installed in a matter of 30min. Solid products, solid information, would recommend these services to family, friends, co-workers. Hell even folks I don’t know. Thanks etrailer!



by:

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.

2003 Ford Escape

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.

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.

2002 Mazda Tribute

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!

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.

When I usually put a trailer wiring harness in I buy the local stuff and then go through all the commotion of trying to get everything to work right never again, bought your product to fit my particular van watched your video then plugged it all in and it worked perfect all for a nice price !!!



by:

I purchased this along with a 75118 hitch. The installation was easy although I am glad I watched the installation video on this website first. The instructions that come with it tell you to take off the trim panels inside the car, this is not necessary. As the video shows, you can run the wires behind the bumper and zip tie them to the hitch. Everything went together easily and it works great.



by:
2001 Ford Escape

Product arrived on the day it was estimated. The shipping package was in good shape, but the main product packaging was slightly damaged although the product inside was perfectly in tact along with all the instructions and hardware. They had exactly what I needed and otherwise a hard to find kit for my older model Ford Escape! Thank you again!



by:

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!



by:

The directions weren't completely accurate or fully encompassing. With knowledge of trailer wiring and the vehicle wiring, it's easily figured out, but the directions have simple mistakes. This wasn't quite "plug and play" due to no access panel to easily route the trailer plug to the exterior of the van. In order to not make a large hole, I cut the wires to the exterior plug and ran just the wires through the body, rather than having to feed the large plug through.



by:
2003 Ford Escape

This was easy it took me about 1 hour since i did it by myself with 2 jack stands. I did watch a video from some one on how to do this and it helped. They don't tell you when you order or look at the pitchers of what comes with the hitch. But they do include 6 wires for the carriage bolts so you don't need to order a separate one like i did. A helpful hint if you have some small wire of any kind use it to lengthen the back 2 wires for the carriage bolts it makes it easier. That is the only thing i wish they would change is that 2 of the six wires were about 4 to 6 inches longer. this was put on a 2003 ford escape and i did not have to mess with heat shield.

2001 Ford Escape

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.



by:
2001 Ford Escape

Product showed up on time and as described, was very easy install, and does the job, the only thing I would like to see different, would be that the wires were closer to the correct length, so not so much would need to be bundled. I realize these are made for many different vehicles and I take that into account, I just don't like wires that are bundled and zip tied. This is not my first purchase from etrailer and as long as they maintain the same level of service I see no reason why it will be my last.



by:
2003 Ford Escape

Outside of my own stupidity, this was a super easy install. (I accidentally plugged the T connector into itself and the vehicle wire back on the bulb) Just an FYI to etrailer, there is a great ground connection on the drivers side if the white wire ran with the yellow one instead of finding one on the passenger side.



by:

Worked liked the page said. Didn't need any instructions. Install was very simple.

by:
2003 Mazda Tribute

Excellent product and I would highly recommend etrailer . This company is the very best and very knowledgable!!!



by:

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.



by:

I purchased a trailer hitch and wiring 10 years ago and was very impressed with the whole experience, from the tech staff to installation of the items.
Over the years I have made several more purchases and have never been disappointed.

  • Which Wiring Harness Fits a 2003 Ford Escape without Towing Package
    The Plug-N-Tow Wiring harness, part 30445 will only work on a Ford Escape equipped with a tow package. For the Escape without the tow package, the T-1 Vehicle Wiring Harness, part # 118343 would be the correct fit. The T-1 Harness would install inline using the existing connections between the factory wiring harness and the taillight assemblies. We have a video of this part being installed on a 2003 Escape that I have linked below.

  • Replacement 4-Way Trailer Connector for a 2001 Ford Escape with Factory 4-Way
    The replacement 4-Way trailer connectors for the 2001 Ford Escape with Factory tow package that we carry have square connectors, # C55255. If you follow your 4-Way wiring forward on the vehicle and it does have a square connector then you can use either of these replacements. If it does not then the only option would be to either splice in a new 4-Way using # 18252 or replace the whole harness using # 118343.

  • What are the Custom Vehicle Trailer Wiring Options for a 2007 Ford Escape
    The Hopkins Custom Fit Vehicle Wiring, # 40455, will fit your 2007 Ford Escape if it has a factory installed tow package. If you are not sure, look for the connector behind the bumper near the drivers side taillight. The factory tow packet is already wired properly so you will not need to add any fuses, converters, or relays. If you cannot find the connector there, or anywhere else, chances are you do not have the factory tow package. If there is a connector, you should check to make sure...

  • What Tool Should be Used to Trim the Heat Shield for Trailer Hitch Install on a 2001 Ford Escape
    Trimming the heat shield to install a trailer hitch on your 2001 Ford Escape does not require a special tool. If you have some tin snips/aviator sheers that is all you will need. If you do not have any you can get some pretty cheap at a hardware store or you might be able to borrow some from an auto parts store or any place that loans out tools. Maybe a neighbor has some you could borrow since these are common tools. I have linked the instructions and a video that shows a typical installation...

    I can do you one better than that!! How about an install video showing the # 118343 being installed on a 2002 Escape? The connectors will plug inline between the taillight assemblies and the vehicle's factory wiring harnesses that feed the taillights.

  • Recommended Components for 2002 Ford Escape Towing
    The factory tow package included the trailer hitch, wiring harness although not fully connected, and engine oil cooler. All automatic Escape models have a transmission cooler as well. If you want to add a piece by piece towing ability, I recommend starting with the Draw-Tite Max-Frame 2" trailer hitch # 75118. Then add the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118343 which plugs into your factory wiring connections behind your tail lights. You will also want...

  • Will Custom Wiring Harness for Ford Escape part 118343 Convert the Separate Turn and Brake Lights
    Yes, it will. The custom wiring harness for the Ford Escape does convert the vehicle 3-wire system (separate turn signal and brake light bulbs) to the trailer 2-wire system (same turn signal and brake light bulb). When you hit the brakes on the Escape the brake lights will light up on the trailer. If you have a turn signal on at the same time you are braking the corresponding turn signal/red light on the trailer will flash while the other side is solid red for the brake light.

  • Does Trailer Wiring Harness For 2003 Ford Escape Without Tow Package Require Upgrading Lights
    For your 2003 Ford Escape without the factory towing package, you will not have to do any upgrading of your vehicle's lights to install and use the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118343. This harness will work perfectly as is without any type of modification to your Escape's lighting. The only thing I recommend adding is mounting brackets, the No-Drill Mount for Electrical Mounting Bracket # 18140 with Mounting Bracket # 18144. These will allow you to...

  • Why Vehicle Wiring Harness, # C55255, Is Not Working In A 2002 Ford Escape
    On your 2002 Ford Escape you do not need the additional relay. That is only for the 2008 and newer Ford Escape. It sounds like you have the port, but do not have the tow package. Unplug the Vehicle Wiring Harness, # C55255, from your port on the vehicle and with a Circuit Tester Kit # PTW2993 check the vehicles port to see if you are getting current to all the pins in the port.

  • I Keep Burning T-One Harnesses 118343 on my 2002 Ford Escape
    They have a 1 year warranty. Since you have burned up 2 of them already, I would check to see if something is wrong on your trailer. These harnesses do have a limit as to the amperage they can deliver to the trailer lights. If that limit is exceeded, either a fuse on the Escape will burn up or the converter will burn up. You could also have an intermittent short on one of the light fixtures. I would tend to think you have too many lights or are drawing too much current through the converter....

  • Trailer Lights Not Working When Headlights are Turned On with a 2003 Mazda Tribute

Make sure the ground for the converter is attached to a clean and corrosion free bare metal surface. If it already is, try moving the ground to a different location. You will also want to check the trailer side connector and wiring. If there is corrosion build up on the trailer connector that could cause problems. Make sure to check the main ground...

    You will want to connect the Vehicle Wiring Harness # 118343 to both taillight assemblies on your 2002 Mazda Tribute. The wiring harness needs signal from both taillights so the trailer's turn signals will function properly. The 4-Pole connector provided by the 118343 harness will provide taillight, right turn/stop, and left turn/stop functions for your trailer. I have attached a help article on trailer wiring for you.

For your ball mount, I recommend the Curt Channel Style Adjustable Ballmount - 2" & 2-5/16" Balls - 14,000 lbs # C45900. This will allow you to adjust the height of the ball for your trailer to tow level. I recommend using the Anti-Rattle Trailer Hitch Receiver Lock for 2" Hitches - 2-5/8" Span # 63232 to secure...

    You may have a ground problem. In your situation, you have a ground that is strong enough to provide some lighting functions but not all. This is called a weak ground.
