Quickly and easily install a 4-way trailer connector on your GMC Yukon XL with this custom harness. T-connector plugs directly into 7-way OEM tow package wiring harness - no cutting, splicing or tapping required.
Features:
Installation
This custom-fit T-connector plugs into your GMC Sierra'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 GMC Sierra, 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.

Quick & easy trailer wiring harness replacement . took less than 15 minutes
Top quality trailer hitch at a very reasonable price!
Chevy 2500 HD 2005 Duramax
Installation was very easy and only took about 15 minutes to hook up and secure wiring on truck.
This product was exactly what was portrayed on line. Wiring harness was very simple to install and works extremely well.
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.
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
Exactly as described. Fit perfectly into my 2014 Silverado bumper outlet.
Easy plug and play simple installation.
Easy to install
Fast delivery, and easy to find products. Second trailer hitch I bought from e-trailer. Great products
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
Perfect fit!
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!!
Unfortunately, the product ordered did not fit my application and I will be returning!

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.
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
Arrived on time and just what I need.
Easy to install works great shipping and communications was fantastic. Now my USMC LED light hitch cover is on the truck without an adapter.
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.
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
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.
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.
Perfect fit. Took 20 minutes to install wire harness and hitch receiver.
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
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.

1 year & still works great, very easy plug & play setup. I recommend putting a small amount of white lithium grease on those connecting, helps protest against rusting.
