Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. 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.
Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.
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 tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.
Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.
Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.
Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Speaker 1: Today, we're gonna be taking a look at a Curt T-connector vehicle wiring harness with a four pole flat trailer connector. This product fits certain years and models of the Ford Edge, Ford Escape, Lincoln MKX, Mercury Mariner, and Mazda Tribute. To ensure that this is a fit for your vehicle, you can use the vehicle fit guide located at etrailer.com. Now this unit provides a four way flat connector at the back of your vehicle to power your trailer's signal lights. It is compatible with five pole, six pole, and seven pole adapters. Adapters are sold separately and it comes with a dust cap for the four way flat connector.
That way, you can cover up the connection points when your plug isn't being used. The black box is the included power taillight converter. This connects directly to the vehicle battery through the wiring to avoid overloading your vehicle's electrical system. That's constructed using surface mount technology for consistent, reliable performance, maximizes trailer light yield and intensity while producing minimal heat, and ensures superior operation in rough road conditions. Now this unit is designed to connect quickly and easily.All you need to do is locate your connection points behind your taillights.
One of the connectors goes to the driver's side. The other one goes to the passenger's side of the vehicle. Now these connectors are custom fit. They're vehicle specific. They're gonna match up perfectly with the ports on the vehicle and they're gonna snap lock together.
Once you have those plugged in, you'll need to make a ground connection. That's your white wire with a ring terminal attached to it. You want to get that grounded to a suitable grounding location with the included grounding screw. Then you'll need to mount your converter box to a safe, out-of-the-way location and you can do that using the included double sided adhesive foam tape. Next, you'll need to run the hot lead to the vehicle battery.
The hot lead is the short black wire coming out of the box. This gets connected to one end of the bundle of wiring with one of the included butt connectors. The other end of the bundle goes to the vehicle battery, gets another butt connector attached to it and connects to one half of the fuse holder.The other half of the fuse holder gets ring terminal attached to it and connects to the positive post of the vehicle battery. It does come with your 15 amp fuse, goes directly in the fuse holder and it's got the cap that goes over to keep it safe and protected. Once you have that done, you can secure any excess or slack in your wiring with the included cable ties. Once your installation's complete, the four way connector's gonna be stowed in an out-of-the-way location within your rear cargo area. Plenty of wire in here. That way, you can extend it out the back when you need to use it. Roll it up and tuck it away when you don't. It is recommended that you use a small amount of dielectric grease on all your electrical connections, like the plugs on the vehicle, on the four pole connector itself. That grease is specifically designed to help prevent corrosion to the connection points. It is sold separately and available at etrailer.com. When it comes to the maximum amperage for the stop and turn lights, we're looking at three amps per circuit.For the taillights, we're looking at six amps per circuit. That's gonna do it for today's look at the Curt T-connector vehicle wiring harness with a four pole flat trailer connector.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.The wiring harness came with everything I needed for the installation. The hardest part of the installation was running the 12 volt power wire from the rear of the car to the engine compartment. I purchased the optional weather-proof connector wit the heat shrink tubing. This ensures a good waterproof connection for the wiring. The only minor complaint that I have is that I don't like the dangling trailer electrical plug-in. It would be nicer if the plug-in could have been mounted to the bottom of the bumper. 644077
Great kit that worked very well! Some of the connectors were exposed and eventually corroded. This was remedied by cutting the connectors off and soldering the connections. In hindsight, I would recommend doing this initially for any exposed connections. Other than that I have no complaints. 651807
Product was shipped quick and as advertised. I will use this company in the future for all of my towing needs 437079
Harness fit good and was easy to install. Only four stars because the video had stated the connectors were upgraded to heat shrink connectors but my connectors were not. I did have some of my own so I swapped them out. 540577
This kit included standard butt connectors, but as referenced at about 4:10 in the video the connectors were upgraded to part # DW05745-10

Rachael H - 07/31/2018can't believe it arrived in less than a week! Best price I found online. Fit perfectly and only took 30 min to install. Happy to write a review for future customers since past reviews were what tipped my vote. Thank you etrailer! 449311

This trailer lighting kit contains everything needed to complete the job. Total time to install the kit on my 2012 Ford Escape was not more than a couple hours. Am very pleased with the quality of the materials, the clarity of the installation instructions, and the ease with which the kit can be installed. 496515
This was my second trailer wiring kit for my 2010 Ford Escape. The first one stopped working correctly after about 4 years due to somehow the little module that was mounted with double sided tape behind the tail light came loose and was dangling down where it was exposed to the elements. The second unit was mounted with a screw and worked like a charm. The only minor difficulty is running the power wiring up to the battery in a manner that it is protected and out of the way. Other than that, easy fast installation in one evening. I’ve since traded that vehicle so I can only assume it’s still working. 723422
Easy install works great. Best price 722333
Installed this on my son's 2011 Ford Escape. Using the simple to follow instructions and the Videos provided by Etrailer made this a simple project. We installed this in conjunction with a receiver hitch, which we also ordered from Etrailer. 720600
Great assistance with determining & ordering trailer hitch, ball & receiver and wiring harness. Product arrived promptly as expected and is now installed on my 2010 Mazda Tribute. Thanks for the expert assistance! 699316
Good product, works great and it was not hard to self install on a Ford Edge. 680932
Very satisfied with the product. The package arrived a little beat up with a significant gash in the side of the box, but the hitch was undamaged and all parts were intact. The hitch installed easily, everything fit as needed, though why the need for a spaced between the hitch and the frame on the passenger side really doesn't make sense, it looks like a fix for a hitch with incorrect mounting hole locations. And that did make the installation a little more difficult, but manageable. The wiring harness also installed easily, everything needed was there and everything worked as it should. I'm quite satisfied. 680881

I love Etrailer.com. The right parts for the job always. Shipping is prompt. Prices are fair. If you need to return an item there is never a hassle. This new harness solved my suspected control module problem. Trailer Brake lights stuck on. Upon braking, the opposite trailer turn signal would come on. Thanks etrailer.com 595487
Easy installation. no issues! 594174
Took some skill to install correctly, but good electrical performance after ine year. 591038
Easy to wire 581937
I had no installation experience when I bought this , but the instructions were so clear that it took a lot less time and a lot less frustration than I expected. You can see the quality as soon as you unpack it. Unlike a lot of assembly instructions, these guys must have tried them out,because they are so clear. So a year later with pretty regular use, no sign of unusual wear and no problems.. Great product and highly, make that very highly recommended. 580152
It works good so far, the last 2 from different suppliers i got only lasted 3 weeks and then 1 week, this seems allot better quality. 559272
Good product bad was the wiring for the box was short 558329
Brilliant solution and easy install. I needed this as the factory installed system was not working and I couldn't resolve it. This is a great fix, inexpensive and the instructions are well documented. Etrailer has a great set of videos with all the steps needed. 555453
