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.Couldn’t get any simpler. I am very pleased with the quality of the product. It arrived as expected with all the items. I watched the installation video and went to work. It took approximately 1hr of crawling under the van but it’s well worth it. Only thing I’m missing is the bracket that mounts the 4way to the hitch. I’ll purchase that and be ready to roll!
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.
Everything fit well and was going just as the installation video showed until I got the power cable to the motor (from underneath the van) and realized it was no where near long enough for my 148WB. Needed at least another 5'. Ended up having to remove the drivers taillight again and fished the cable inside the van from there and ran it right to the battery under the seat.
Sierra K - 07/22/2021Lighting kit was very easy to install. I watched the video first, which was very helpful.
Fit perfectly and easy to install with the e-trailer video!
perfect fit for 2015 Ford Transit T150
The 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.
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.

disappointed, wire provided to connect to battery was too short, requiring a splice, followed the suggested route still 12"-18" short
Heather A - 02/25/2021E Trailer is always punctual, professional,and knowledgeable. I appreciate an online vendor that checks all of the boxes!
Everything 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 - 04/03/2020The 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.
Overall an excellent product. The only small detail that I thought needed improvement was the self tapping screw for the ground. It was very small. I added my own screw to complete the install.
Easy 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'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.
I am totally satisfied with the wiring harness I bought at etrailer. It worked fine and were a good quality.
Good product, easy to install.
So easy to install. Awsome. Received it yesterday and just finished installing it this morning. Thank you.
Miranda was super helpful when we ordered, everything was shipped and arrived extremely quickly, and everything has held up well!
Nice and easy to install. videos where great
I 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.
exactement ce que je cherchais. merci b eaucoup.
Good product, easy directions
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!
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.
