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 you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.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.
A ModuLite power module 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. This power module functions as a tail light converter to combine 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.
With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

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. Powered ModuLite reduces strain on wiring system.Worked great and easy to install for the most part. Running the power wire is the hardest part having to squirm under the transit do often. Lol I did change one thing from the install vid for my 2016 Transit. I connected the power wire to the second terminal so I didn’t have to modify the cover like the video suggests. It just unclips front and back and then snaps back on. See pix.
disappointed, wire provided to connect to battery was too short, requiring a splice, followed the suggested route still 12"-18" short
Heather A - 02/25/2021The installation video for the 2018 Ford Transit was extremely helpful. Though my Transit is a 2019, and the wire to the battery needs to be threaded up into the cab where the battery is located under the seat, all other instructions were accurate and helpful. There is plenty of wire to reach all locations. I needed another pair of hands to help with threading the connections up to the tail lights.
Lighting kit was very easy to install. I watched the video first, which was very helpful.
The wiring harness went in perfectly, the only part that was annoying was running a wire all the way up to the front of the van and up into the fuse box.
I've purchased two tow packages from etrailer and both have worked great for several years. Installation was easy both times (two different vehicles). I would definitely buy from etrailer.com again.
Very helpful ordering service. Lots of knowledge. Ford required $260.00 for a flat 4 wire trailer module harness, E-trailer price was around $50.00 including freight. Shipping time was fast.
Frank - 02/16/2020Everything was as you advertised. Everything went so smooth even the one armed man could do it in his driveway. Both the trailer hitch and the wiring was great. I am going to do camping and am turning the back of my van into a RV. Will be planning on pulling a utility trailer for all my extra needs. The hitch I chose is a little over kill. But better safe than sorry.
Johnny - 04/03/2020Easy plug n play wiring harness with 4 pole connector. Wires were sufficiently long enough to properly secure along the vehicle frame. Kit comes with zip ties to hold and hide wires. We tapped the ground wire to a tie down bolt to the frame and ran the positive wire to the battery. This was a fairly easy install on our 2018 Transit.
King - 08/28/2019I am totally satisfied with the wiring harness I bought at etrailer. It worked fine and were a good quality.
I've purchases two tow packages from etrailer and have been very happy with both. I've used them for several years without any problems. Installation was easy.
I didn't use this product the motor home was already equipped for towing.
Simple install! The only catch is that there is barely enough wire to reach the front if you have along wheel base van like I have. So route the wire carefully. Also it would really help if you have pro grade wire crimpers for the yellow butt connectors provided as they are tough with little ones. Luckily I have a set of Klein with long handles. Oh yeah and have some extra zip ties handy and possibly some water tight butt connectors that I luckily had!
Hitch and wiring kit were received but the shipping box was not in good condition. The metal was sticking out of the box and the wiring kit box was smashed but nothing was damaged inside the wiring kit box. The receiver hitch did suffer some scratches. The order was shipped out quickly and was a really good value. I will be installing it soon.
Curt hitch was easy to install with no modifications.
I am reluctant to write this review because I have not used my new trailer receiver yet. What I did wanted to comment on was the amazing customer service that I have received. I don't know if I can say this but it's is my opinion.. What Crutchfield is to car audio, etrailer Com is to trailers.. I picked out the trail hitch I needed for my van. Then called in and a sails rep promptly help me with the electric components I needed and some other accessories.. Zip bag pow there on my door step.. After watching the how to install video associated with the products I ordered.. I had my trailer hitch installed in 30 minutes.. I still need to install the electric components but the video, and the help I received from the knowledgeable staff at etrailer. Com I'm sure it wi be mind numbing.. I know this sounds like I was paid to write this.. But every once in awhile I come across a company that is the real deal.. Thank you etrailer Com.. I would definitely recommend your site to family, friends, and most of all the guys I work with.. Who will buy your products.. I will update with pics after I have put my curt trailer hitch to the test
This product worked great, simple plug and play, and came with every little extra that you need. This has been true of every vehicle-specific harness I have bought from etrailer.
Nice and easy to install. videos where great
Videos included with trailer hitch and wiring setup were spot on. I installed trailer hitch in 30 minutes. Wiring took 1 1/2 hours. I recommend you purchase the wire tester if installing by yourself. Well worth the few bucks to make sure all lights, tail and stop are working. Plan on purchasing super springs next.
The wiring installation went smoothly. After 1 year the wire we installed from the front of the vehicle rusted off where we connected it to etrailer's wiring at the rear. That was because we failed to wrap it with electrical tape. etrailer's wiring continues to work well.
Easy install on my Ford Transit 250, the video was very helpful. I would recommend getting 18 feet of conduit to route the wires under the van (12 volt black), under the bumper, and in between the doors. running the wire under the van was the most difficult part (only because I had to crawl under the van), but there is easy routing all along the left(driver's side) frame rail into the engine compartment.
Tony M - 07/05/2016I had a what I would call a sending unit bad with first wiring harness. I talked to two people on the help line. Nothing they suggested helped. A man from technical support called. He had several questions and then diagnosed the problem over the telephone. They immediately sent a new harness. All three people I talked to were very nice, couldn't ask for better service. Trailer hitch and wiring harness all working great.
Worked fine , Battery in the 2019 Transit a little hard to get to, It is under drivers seat. Otherwise worked as stated.
Wiring kit for Ford Transit went well....Directions in package good except for telling you to connect 12 v. wire from battery to the RED on the connector box....there is no red.....go black to black.....Hooked up to my trailer....All went well.....The video on UTUBE was excellent.....just follow those instructions...…
