Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the center of your rear bumper.
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.

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into OEM tow package wiring harness - no cutting, splicing or tapping required.5 star on quality, 4 star on instructions. I’m pretty good with mechanical things. This was not difficult to install. The access holes provided were like 7/8” but bolt heads are 1-1/16” so needed to enlarge those holes using a 1/2” drill bit. Instructions said to disconnect muffler but I did not and was able to get it in place. Need to remove four screws, two on each side from center, on the bumper cover and pull back to install. Used jack stands to assist. Did not need to trim any of the cover. Fishing lines worked great too; just put a good kink in them to pass easy to the access hole. Did have to trim two bolts projecting from the bumper bracket and then it fit great, all bolts lined up. Adapter for lights was perfect also, bit hard to reach and disconnect cover though. Overall very happy with this product.
Direct fit for a 2021 Chevy Blazer premiere installed a hitch, and this wiring harness at the same time. I figured since the bumper was off, I would be able to install this quick and easy and it was. Just had to take the dust and weather cover off existing plug that was behind the driver side, bumper and plug this wiring harness right in. As you can see from pictures pretty straightforward install.
Excellent product and the easiest system for attaching to your vehicle! You only need a second person to hold the hitch up while you get the first nut on each side. The wiring harness is click-and-play. if you need a visual, watch the provided videos. Highly recommend this product to everyone!!!
Very easy to install. Remove cover from wiring harness on vehicle and plug in the wiring harness. So simple that every one is able to do this.
Hi, e-trailer always very responsive and now I have to install it!!!
Once again, very easy to remove and install new plug. Nice to have the YouTube video to instruct how to disconnect the plug.
Great product and video showing how to install on specific vehicle. Went on as shown, with no difficulty at all.
Plugs right into the factory harness on my 2021 Blazer RS and works geeat.
Very nice pigtail! Easy install.
Everything is good. Measurements and quality. Thanks!
The wiring harness was very easy to install, but the hitch installation took a little time. It went on good after a little time figuring out the mounting hardware. The videos on this site helped make the installation a little easier to understand.
Always a great experience shopping with Etrailer. Our products arrived in one day!
perfect fit for what I needed. no issues whatsoever.
Look, I don't know if my product works yet. But they reached out to me the moment it was delivered. I am sure if there are issues they will help but I am thrilled with the customer service. This also came several days early. Would recommend.
I was very pleasantly surprised by the ease of this wiring harness installation. I installed a wiring harness on a Jeep a few months ago. This was literally plug and play.
Your product is top knotch and well worth the price! Easy installation! Fast shipping! I couldn’t be happier! I have already installed this! Thankyou!
Makes wiring easy, the only issue I had was getting the protective plug out. I thought once you slid the red tab back, you could pull it out, but there is a tab you have to push also, once I figured this out, no problem.
Fit my 2017 xt5 works great.
So easy, was very happy to find that cadillac had this plug on every model, even the ones that came without the top package. Sdding lights is plug and play, no tapping into wires of the car.
Simple plug and play. Worked perfectly.
Delivery was quick and arrived in great shape. Looked perfect out of box. Videos were extremely helpful although didn’t indicate to remove calking at back of frame rail. Hitch had to be trimmed to clear muffler hanger bolts. That held up progress a bit. All in all final product looks great but took a lot more effort than indicated by video. Installed mine with car on ramps in about six hours. Suggest having at least a couple extra sets of hands. We have ordered alot from Etrailer for the camper we built and everything arrived in perfect shape. First place I look for needed products.
Easy to install
The hitch is everything I could ask for. It is designed very well for my Blazer. Because it's concealed by a panel on the bumper, no one knows there's a trailer hitch
Thanks.
Fits perfect. Getting stock harness plug off was a pain, but that is a GM issue not the new harness. New harness plugged right in with no issues.
Only item that I feel that is missing and needs to be a part of it or a side order item is a part that it can plug into to then attach to the tow hitch.
