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 either the tail light assemblies or interior trim panels to access this harness.


T-One Connection Location Points Behind Tail Lights

Once installation is complete, the 4-way flat connector will be stowed either in the jack storage compartment of your cargo area or beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure if you are mounting it near the hitch.


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.

This trailer harness has performed perfectly over the past 12 months. I would definitely recommend it to others.

This website is awesome. The amount of accessories that you can find for one model is amazing. And for each of those parts there are informational videos on how to install it.

Product arrived very quickly and was very easy to install. I was absolutely dreading wiring the trailer little on this van and this harness made the job very simple!

Been a year and the lights are still working like a charm! I highly recommend this product!



by:

I had put off wiring my van for a harness to go with my trailer because just the idea of running wires and tapping in to the right places, testing it all and sealing it back up was full of concern if I would get it right, how much time it would take, ... I was thinking just how frustrated I might become and so I put it off over and over again.

Then I found your site and your information. I looked up my vehicle and the part I needed. I called your number and spoke with a very helpful customer service representative. She looked up the instructions and even read part of it to me. She said the harness has two leads that just go between your tail lights and the wiring from your vehicle. They just plug right in.

I ordered the part with 2 day shipping and it came right on time. Installation was a snap. I was probably done in 15 to 20 minutes in all and the trailer lights work perfectly. The job I needed to do the next day was a breeze because I now had access to the trailer with confidence.

I even went to the store I bought my trailer from and told them about you all so they could tell other people.

Thanks for being so helpful and providing such a great product!

I love it. Went all over town looking for help with the trailer light hook-up truck side for a 2002 Ford Ranger. I was told that the truck was factory pre-wired and there was nothing that could be done but follow the wires to find the problem and then fix the problem. Cost about $75.00. Called etrailer and they told me how to do the repair without the hassle. Ordered the part, fixed it in about an hour. Thanks etrailer. You saved me about $50.00. The harness was easy to use, just open up the lights and snap in the plugs.



by:

Used this to tap into my turn signals for my snow plow. The wire loom was very short next to my turn signals and this allowed me to tap into the tight bend with plugs instead of splices. These will keep the connectors from corroding. I am glad I found these for my Excursion, it saved a lot of frustration of trying to splice in tight areas. I highly recommend these for any project. Well worth the money.



by:

First off with all the information available to you on the etrailer website it would be hard to buy the wrong parts. With that information I already knew what needed to be done before my wiring adapter came. The instructions were also easy to understand when i looked at them. The adapter easily plugged into the back of the tail lights just as described and my trailer lights worked perfectly. From order, to emails about my order to a quick delivery this could not have been any easier. This is my third time ordering from etrailer and I always look at there website when I need to set up for towing. Sorry no pics job was to easy.

1997 Ford Van

I've bought a tow hitch and parts for a boat trailer I was building. These guys have the best service, the cheapest price, and the highest quality parts. I would rather wait the couple days it takes to get my order and have it right than to have to scurry from store to store dealing with some sales person that has a whole 8 hours training (maybe) trying to find what you need. Anyway, etrailer solves that problem. Thanks



by:
2000 Ford Ranger

The harness is easy to install on my 2000 Ranger. I have a set of magnetic trailer lights that I used to test it and everything worked right (left, right, brake, backup). This is my second purchase of this harness. The first one I pushed the loose wiring up into my spare tire with the intention of fastening it with tie-wraps later. When I saw the torn wiring hanging loose later, I realized what I forgot to do. On this one I fastened it as part of the installation (words to the wise).



by:
1997 Ford F-150 and F-250 Light Duty

The running lights on my trailer would not work because of a short in the wiring harness on my truck. I purchased this harness from etrailer which took about 20 minutes to install. Now all the lights are working on my trailer. I would definitely recommend this product.



by:

Easy to Install. Works great. Just needed a tie-wrap to fasten trailer connector to truck body to keep it from hanging down. I bought one earlier and tried just wrapping the wiring around a brace, but it worked loose and tore off. No problems now.

Bought bumper hitch and it was recommended to also purchase a wiring harness designed for my type of vehicle. These guys know their what makes it easy to install their products

2001 Ford Explorer

this kit came extremely fast. I ordered on the weekend and had it in my hand by mid-week. although my vehicle was not named in the instructions specifically, it was still not hard to install. It took longer to route the wires under the plastic trim than anything else. My Ford is 10 years old so sometimes things don't always go right. but this kit worked perfectly. Took about 20 minutes. I highly recommend Etrailer.



by:

It's a nice harness



by:
Ford

I would have given it 5 stars but the connectors were not correct for my vehicle. This claims to fit a 2002 Ford Sport Trac but my plugs are slightly different. I had to modify this connector a bit which slowed what would have been a quick easy install. Ford may have used slightly different connectors on certain Sport Tracs that year but the manufacturer of this connector should be aware. Fortunately it was just ringing out one of the tabs blocking it from going together. etrailer's price was lowest and the delivery was prompt. I am a return customer.



by:
2000 Ford Ranger

Product, item 118344, fit as instructed on my 2000 Ford Ranger XLT. Easy to do, only taking about 30 minutes to install within the factory harness/connectors. Instructions seemed a little vague to begin with but after looking at product and reading directions again all made sense. The T-One wiring harness works great and the harness wiring length was more than enough to make fitting and routing easy underneath my truck. Thanks to your Expert for all his assistance and if needed, will do business with you again. I have, and will continue, to recommend your business. Howard



by:
1999 Ford F-150

I ordered a T-One Wiring Harness with 4 Pole Trailer Connector for a 1999 Ford F-150 late on a Friday. I received confirmation of my order and notice of shipment the same night. The wiring harness was received Monday and installed the same day. Two day turnaround on my order was fantastic. The instructions made installation easy. eTrailer.com knows what good customer service is all about. I will certainly recommend them in the future.



by:

I have ordered several hitches and wiring kits in the past from eTrailer and will continue to do so if the quality, price and exceptional service remains. Because of receiving earlier than expected, I have not installed my most recently purchased receiver hitch and wiring harness but I have unpackaged it and all looks to be top quality and intact.



by:
1996 Ford Van

Received the Draw-Tite hitch (#75703) as scheduled. On my 96 Ford E-150 van installation was very simple only had to drill two holes. Also the wiring t-connector kit (#118344) installed easily. Both products were excellent quality.

I recently purchased a T-One wiring harness for my 02 Ford Ranger. I'm extremely satisfied with this product it was easy to install and works perfectly. It saved me a lot of time in the process of wiring my truck for a trailer plug in.

seam like it took a long time to get product after it was order



by:
2000 Mercedes E-250

Product was easy to find on the website, good price, fast delivery and snapped right in. Actually I was just here to find a couple of receiver hitches that will fit Ford E250 vans and this wiring harness was recommended on the same page. Much better than my last hack-job trying to wire in trailer lights myself.

I am pleased.

1997 Ford Aerostar

It was just like ever ties real simple to put in save me the hassle of paying $300 just to see what was wrong but then did research and found this wire kit and it works great I've had it for one year had no problems love it

Simple to install works perfect.Ford dealer could not get this without new wiring harness for truck $375. etrailer got it for me in 3 days $30 with express shipping!

Installed on my 2002 Ford Ranger. while installing a Curtis hitch. Easy to install and works like a champ. I would have be done sooner if I have read the included instructions more thoroughly. Simply plug in. No splicing required!

  • Parts Needed to Install Tekonsha P2 Trailer Brake Controller on a 2000 Ford Ranger
    The 2000 Ford Ranger does not have a plug or wire bundle under the dash to install a brake controller. You will need to hardwire in the controller. To do this you will need to first add a 4-Way trailer wiring harness, # 118344, unless you already have one. Then you would need a 4 and 7-Way installation kit # ETBC7. I have included some links that explain and show the installation of the ETBC7 kit. The video is on a 2002 Ford Ranger and it will be very similar on your truck.

  • High Capacity Trailer Hitch, Brake Controller and Wiring Recommendation for 1998 Ford Van
    For your 1998 Ford F-350 we have the Curt hitch part # 14053 which has a 10k capacity that would work well. For trailer wiring you will need to start with a 4-way (if you do not have one). For that you would want the # 118344. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product...

  • Recommended Trailer Hitch And Wiring For 2001 Ford Excursion 4x4 With 5.4L Engine
    I did some research on your 2001 Excursion 4x4 and found the towing capacity for your vehicle with a 5.4L engine is 7,200 maximum trailer weight. That would be the weight of the trailer when it is fully-loaded and ready-to-tow. For your Excursion I recommend the Curt Class trailer Hitch, part # C14011. This is a Class lV hitch and it has a 2 inch receiver opening. Since you plan on doing some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts;...

  • Installing the Redarc Tow-Pro Elite # RED44FR in a 2001 Ford Ranger
    The Redarc Tow-Pro Elite # RED44FR is a great brake controller, but since it is still fairly new to use we haven't had the opportunity to shoot an install video on a Ford Ranger yet. I do have some dimensions that you can use to determine if it will fit though. The main unit of the Elite measures 3-3/8" long x 3-15/16" wide x 1-1/8" tall while the control knob itself measures 2-3/8" long x 3/4" wide x 7/8" tall.

  • Compatibility of 4-Pole and 7-Way Trailer Connectors on 2003 Ford F-150
    If your existing 4-pole harness is a factory part that plugs in to an OEM connector like those on Tow Ready harness kit # 118242, you can have both harnesses active at the same time by daisy-chaining then together. If you have an aftermarket 4-pole harness that connects to the truck's taillight wiring then again both will still remain active since they connect to the truck independently of one another.

  • Trailer Hitch and Wiring for a 2000 Ford Excursion
    The 2000 Ford Excursion is actually rated for 10,000 pounds gross trailer weight. The 18,000 pounds is the gross combined weight rating or GCWR. The GCWR is the most that the Excursion and trailer can weigh including cargo, passengers, and fuel. So the Excursion cannot tow 18,000 pounds and its weight plus the trailers weight cannot exceed 18,000 pounds. The trailer can weigh up to 10,000 pounds total but no more. With that said the highest capacity trailer hitch we have for your vehicle...

  • Trailer Brake Controller Recommendation for a 1997 Ford F-150 Towing a Travel Trailer
    If your 1997 Ford F-150 came with a 7-Way wiring connector at the back from the factory then all of the wiring and everything needed is already on your truck so the installation will be pretty simple! I recommend using the Tekonsha Prodigy P2 # 90885 which connects to your truck wiring using the adapter # 3035-P. I really like this brake controller for a few reasons; it's a great entry-level controller that's easy to use and it's backed by a limited lifetime warranty so you can be confident...

  • Trailer Hitch Recommendation for 2004 Ford F150
    2004 was a split model year for the Ford F150. Two F150 models were offered, the Heritage which was the rounded body style like the 2003 model or the new body style, like the 2005 model. The hitch you need will depend on which body style your truck is. If you have the new body style, I'd recommend the Draw-Tite Class III hitch, part # 41549. Some of the new body trucks had a vibration dampener at the rear of the vehicle. The hitch includes a bracket that lets the vibration dampener be...

    For your 2002 Ford E150 Van, the relays and fuses only make sense when you have the factory 7-way. When you don't have the factory 7-way, then you need to use a different wiring harness to get your features. Since you have a 4-way it is very likely that the connections are spliced into your factory wiring and there may be a connection issue there. You can use a circuit tester like # PTW2993 to probe each wire and you should have power and correct function when using a good vehicle frame...

  • Recommended Hitch for a 2001 Ford E-350 Ecoline Van

This hitch is custom fit and bolts directly to your E-350 Ecoline van with included hardware.

It is possible though that the T-connectors such as # 118344 for the 1997 Ford E-350 will not fit the RV body if it uses different lights than the regular E-350 vans.
