  • 4 Flat
  • No Converter
  • CURT

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into 7-way OEM tow package wiring harness - no cutting, splicing or tapping required.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Designed for use with a factory tow package that has a 7-way connector
    • Retains 7-way connector functionality
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points behind rear bumper
    • Plug in T-connector
  • Comes with dust cap for 4-way flat connector
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness, which is located behind the rear bumper. Simply plug the harness in-line with your existing 7-way wiring harness.


Once installation is complete, the 4-way 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.

I installed an aftermarket rear bumper, after which my my wiring harness wouldn’t reach. This extension was exactly what I needed and it works great!

Jeep Grand Cherokee

Order arrived timely and was packaged well. Price point was reasonable for the items. All parts and fasteners were included and of good quality. Instructions were included that made the installation simple. I also found a [online] video that showed the installation on my exact vehicle (Jeep Grand Cherokee) which made the installation a perfect match. Parts installed exactly as shown in the [online] video.



by:

Was exactly as stated in description. Just unplugged old plug and plugged in new one. I had two plugs to replace and added an extra "T" plug for another 4 prong. It only took less than 15 minutes to install all 3. Customer service is wonderful. Everything I have bought from ETrailer is top notch and delivered on time or earlier.



by:

Helped me put lights on my mudflaps and still allow me to hook up my trailer.



by:

Install was pretty straight forward, plug and play, only 1 wire i had to route to the battery up front. I put this on my wife's 2020 Grand Cherokee along with the curt aftermarket hitch since the car had neither. Easy install of less than 1 hour. So far no issues with anything!!

Order class iii hitch and wiring harness for my 13 keep grand Cherokee . Came next day. Installed in 20 minutes. Great product. High quality and easy install

Product was shrink wrapped, taped and boxed ver professionally. Website also very easy to use

Would definitely recommend to anyone



by:
2020 GMC Sierra 1500

Very easy to use, hardest part is getting under the vehicle, I have used to connect the light bar, install time 5-10 minutes, comes with zip ties, very happy with results.



by:

This T-Connector is working great. Installation was simple. It was truly plug n play.
I used it to connect a LED light bar on back of truck; allowed me to install the light without using the existing trailer connector, so it is still available.

Bolted right up to original hitch that rusted away on my 2008 Chevy Silverado. Harness that came with it was different than my original I was unable to use it. My harness was fine so I just saved it for another day. Shipping was fast and convenient.



by:

This is a great vehicle to trailer wiring harness just plug it in and you're ready to go and that's all they are to it plug and go and I recommend it.

Easy to install works great shipping and communications was fantastic. Now my USMC LED light hitch cover is on the truck without an adapter.

2018 Dodge Ram Pickup

I installed my Curt T-Connector today to my 2018 RAM 1500 Sport 4x4 Crew Cab. The mileage on the truck is at 10679km's. Although warned that the spare tire might require removal (via web site info from fellow RAM owners) that was not the case as there was enough room to remove the OEM connector (which is the short end of the assembly) from the factory housing. The actual disconnect and re-connect took only a couple minutes. I spent a about 15 or 20min's trying different wiring run routings for the aux. four connector plug wiring run. Some tie-wraps where installed to snug things up out of the way and I was done. I also dosed the connections with a shot of Krown 77 lube/rust inhibitor. I'm in the "Great White North" so salt use on roads is a given during the winter months. A quick test run of the lights and I was done. The build quality of the T-Connector is very good..equal to OEM or better I'd say.



by:

Perfect fit. Took 20 minutes to install wire harness and hitch receiver.

Watch the install video. Easy, peasy.



by:
2011 Chevrolet Silverado

Took less then 5 min to install, solved the hassle of going to a brand name shop and paying 5 to 6 times to have them install. Plan on towing a utility trailer my wife and I do a lot of antique shopping. Will tell all my friends, great product

works great no problems

The product is great!! My only problem was with the OEM connector. Unlocking it was a hassle. I think I ended up breaking the snap lock in the end.



by:

Awesome!! I bought an OPT7 triple LED light bar for my Chevy Colorado and I didn’t want to splice wires or lose a whole lot of time trying to figure out how to wire it up so I googled and I came across a gentleman who used this product and Im very thankful for this connection and my light bar works smoothly and I have full use of the reverse camera AND I don’t have any wire mess outside or underneath my truck! Easy to install, my first time doing this and it literally took me about 2 minutes, if that! Definitely would recommend this product to anyone with a truck!! Thank you guys!!



by:

Plugs right into the pre-wired connector. Very easy to install.



by:

Easy to install and tucks away nicely next to the hitch. No hanging wires and really clean look



by:
2014 Nissan Titan

This T-connector wiring harness was exactly what I needed for connecting my standard 4-wire trailer lights to my 2014 Titan. It was easy to install (5 minutes), it is well made, fit my truck exactly, and everything worked when energized. Good price, quick shipping. Highly recommend. Thanks

Bought another truck and plan on adding a light bar to it, like my other truck and this T connector works perfectly... Thank you etrailer!!

So far so good, no problems!

Excellent product. Fits great! It took me longer to figure out how to unhook the wiring on the truck (without break it) than it did to install this 4 wire plug-in! I will shop with your company in the future. I've build many trailers and wired them to different vehicles over my life time. These plug-in wiring products are the way to go!


Comments
Great product!Wiring harness works perfect. It was very easy to install. The worse part was getting my trucks harness to come apart. My truck is a 2014 Chevy Silverado so it had some dirt, etc making that connection a little tough to take apart without break it. But this wiring harness was great.Im getting old 76 and no longer build trailers from scratch. Ive laid on my back many times trying to locate the correct wires on a vehicle to install a connector and then solder the wires in place. These connectors would have made life a lot easier.
