Adding trailer lights usually means cutting wires, but this T-Connector skips that mess. It plugs directly into your vehicle’s factory wiring to give you a 4-flat connection. No splicing, no guessing which wire is which—just a clean, straightforward hookup that keeps your original wiring intact.
Once installed, the harness provides the standard 4-flat trailer connector. That gives your trailer running lights, turn signals, and brake lights so you’re fully visible and legal on the road. It’s everything you need to handle basic towing safely and confidently.
If your vehicle didn’t come with a factory tow package, this harness covers that gap. The integrated converter module makes the trailer lights work correctly by matching your vehicle’s wiring output to what the trailer needs. It’s designed to handle the job even when the factory setup isn’t tow-ready.
The harness is built with a hidden, plug-in design that tucks neatly behind trim panels or existing grommets. That keeps the wiring out of sight and safe from dirt or damage. The result is a professional-looking install that doesn’t leave loose wires hanging below the bumper.

“Real” customer service. Great product, fast shipping, outstanding communication.
Everything was perfect. All items shipped and arrived when stated. The video for installation was perfect.
Thank you.
Open box and found order in tact, without unwrapping nuts & bolts. Had one of these receivers on a previous car and had no problems.
Great price and Fast shipping. The step by step videos are excellent and spot one. Customer for life. Can’t say enough good things about e trailer.
Great product and easy install. Installation instructions were very helpful.
Products are excellent quality and service provided by your shipping group is timely and helpful!
You guys were great with my order. But the wrong package was delivered to me. I’m pretty sure the driver grabbed the wrong box and mine is still on the truck. I called the person whose package I received and he will come and get it because he is close by. I called UPS and they weren’t very helpful. I may still get it today when the driver realizes his mistake or maybe tomorrow. You may need to call and file a claim.
Works fine but package didn't contain a fuse, adhesive tape for module ,a ground screw, or wire ties per description (photo)
I ordered a trailer hitch. Before it reached me, it was rerouted from the post office near my home in California, back to the East Coast. I contacted etrailer. I was given a date it would arrive, and promised I would be contacted if the date would change. This was important, because I had a trip planned and needed the hitch installed. That date came and went with no call from etrailer, and no delivery of the hitch. When I finally received the shipment (4 days after the promised date),the box it came in was destroyed, and opened. I tried to lift the box and the bottom gave way. The hitch was hanging out one end of the box, and was scratched up. The smaller boxes/packages inside were smashwd, opened as well. The box was also left, not at my door, but at the base of my driveway. I contacted etrailer. They asked ME to tape up/ repackage the box so they could retrieve it ( Seriously, they wanted ME to repair the box! WOW!!) They offered to send me a replacement, however, no guarantees were given that it would arrive promptly. Also, no offer of a small discount or compensation was made for my trouble ( or services for reparing the damaged box). I will not do business with them again. They are not a stand-up company who is reliable,and can be trusted to keep their word and act with integrity.
The installation video was super helpful! - Watch the video, then go under the vehicle and take a look since things are always 100% the same (my heat shield was slightly different), then watch the video again. You'll need to purchase a die grinder drill bit on [online] for $10 if you don't already have one. Wear eye protection! Everything went super smoothly!
Super easy with the Hybrid model, since the battery is under the spare tire and you don't need to remove the tail lights, all the connections needed are behind the rear side panels.
Everything that I needed was in the kit undamaged. I used the installation video and everything went according to the video. I am quite pleased and will purchase from etrailer in the future.
Great kit. I wish I had watched the video first but I was outdoors and charged ahead with the printed instructions which had me removing a taillight before I realized that was not necessary to gain access to the plug.
Easy install, works great, got it quickly. Thx
As advertised for 2020 Ford Escape Hybrid. Order was shipped immediately with updated tracking. Video helpful during installation. Having the battery in the same area made for an easy install. Have purchased through E-trailer several times and customer service has always been great. Would not hesitate to use again.
This wiring is for add-on trailer hitch and allows connecting tail-lights wiring from RV without cutting original vehicle wiring when being towed.
East instal awesome install video . Tha nks
Video instructions were very good. Good quality connectors, easy to insall. Note that if you're doing this on an Escape Hybrid like I was, installation is much easier because the 12v battery is right in the rear compartment under the spare tire. The hardest part of the job on a non-hybrid would be snaking the wire under the car to the engine compartment (which I wasted time starting to do before realizing I didn't have to. Doh!).
It’s a little tricky to get installed but if you take your time it works great. No issues at all with the product.
Fit perfectly, easy to install on my phev 2021 escape.
Installation video was very helpful. Made a lot more sense than the included written instructions. I have a 2022 Ford Escape PHEV so attaching to the rear battery made this very easy to install. Nothing against this kit. But I wish there was a way to run it to an exterior receptacle. Running the cord out the lift gate isn't as clean and worrying about wear and tear on the wire is not something I prefer.
The electrical kit had everything required. The instructions do not cover the Hybrid explicitly. However, with the 12v battery in the rear compartment, it is an easier install than standard vehicles with the battery under the hood. Otherwise, the instructions are excellent.
The YouTube video was very helpful. The kit went in without issue.
Overall, this was an easy install and the tutorial helped a lot for the initial steps. I have the non hybrid escape and here’s some helpful tips for install. When running the black wire there is a black oval rubber grommet at the back of the trunk close to where the top of the spare tire sits. Make a small hole in this to run the cable. Pull it through. Then when under the car, run this cable along the brake line for about 1 foot. Then run the cable down and near where the runner board is, there is a plastic hollow piece underneath the car that allows you to zip tie the wire about every foot. When near the front driver side wheel well run the cable up behind the cars wheel well cover and the wire will pop out right by the battery. This was the easier way to do it and did not require a jack, lift, or speciality tools. Overall the product was great, the tutorial should have used both the hybrid and the standard version (doing the easy version in the tutorial is just lazy and inconvenient for the customer). Lastly I was not a huge fan of any of the connectors, all the crimp ons were a bit flimsy and leave no room for error, I crimped them correctly and they were still loose (had to nearly crush them and still had to use electrical tape). Otherwise the product has worked as intended.
I first bought one from ebay motors. Everything worked except the turn signals. I then came here and bought this one. everything works perfect. I recommend not buying an off brand. If you are looking at the price, be assured this is the better deal because it works.
