2018 Chevrolet Tahoe - Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector

  • Trailer Hitch Wiring
  • 4 Flat
  • No Converter
  • CURT

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


  • 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


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.

Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector - C55384

Average Customer Rating:  4.8 out of 5 stars   (606 Customer Reviews)

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.


This product was exactly what was portrayed on line. Wiring harness was very simple to install and works extremely well.


When I finally installed it about 3 months ago, the plug in connectors did not match what I had on my truck. I ended up just cutting them off and splicing them into the connector from my truck


Yup. Still works after a year in operation. The only thing I am unhappy with is my vehicle thinks there is always a trailer connected and the backup sensors and side sensors are automatically disabled.


Fast delivery, and easy to find products. Second trailer hitch I bought from e-trailer. Great products

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.


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.



Working GREAT. Easy to install

2022 Chevrolet Silverado 1500

This is such a better way to install a tail light bar. No cutting or splicing wires! FABULOUS!


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!!

2019 Ford Ranger

Easy instructions, installation was a breeze. Very important to torque bolts down to spec. Also will need to have dealer “flash” vehicle to activate trailer lights. 5 stars


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.

Its been a year since I installed the T-Connector. And it is still working like brand new no issues with this connector. Provides a great convenience not having the share the OEM trailer slot.


Did not match my plug into car. So could not use and returned.

Can you please provide a picture of the underside where the plug is supposed to be located? For vehicles with the factory tow package; your install may require additional components or may be used as a replacement harness.


You sent me the wrong wiring kit. It doesnt work on my vehicle.

This harness is meant to be used for a 2023 Ford Explorer that has a factory seven way to add on a four flat. If you do not have the factory seven way, then you will want to use part # C56093 instead.

2023 Chevrolet Silverado 2500

product looks nice its plug and play so pretty much anybody can install it delivery was a little slow not your fault usps that says it all thanks again

2001 Chevrolet Silverado

Unfortunately, the product ordered did not fit my application and I will be returning!

Etrailer Expert

Jenny N.


I wanted to ask if your 2001 Chevy Silverado came with the tow package? Did you already have a factory seven way? If not, the part # C59236 would be the better fit.


The T-Connector plugged right in and worked beautifully!

2013 Chevrolet Avalanche

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

2013 Jeep Grand Cherokee

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


Everything works great! Affordable price & easy assembling. Towed my boat and other trailers all summer with no issues.


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


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.




Quick & easy trailer wiring harness replacement . took less than 15 minutes

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


simple install. the components are sturdy and seem to be designed for durability. 12 months no issues


Took forever to get it just being 250 miles away from where it was in a store and when I got it, it was for even the wrong make up truck. I have forwarded this was for GMC or Dodge. I could be wrong, but I thought I ordered one for a 2003 Ford ranger
