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.by: Steven04/19/2022
I bought the wiring harness to use on my boat trailer. but since then I have used it on a number of trailers. I have let some friends use it for there trailers also.
by: Ben05/28/2022
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.
by: Joseph 06/24/2022
Easy to install, it was the right fit for vehicle. I have been using it for a year and have no issues.
by: Donald02/22/2022
it took longer to ship than the Hitch & the video on your site for a Blazer isn't a RS it takes a few more steps that would confuse the normal DIY er

Hitch Fit as stated,it went together well. Son in law and I put it on in about 1 1/2 hr on a blacktop driveway. We were pleased an it was a good project with money saved. Also wire harness for trailer was very easy plug in route. Lights even worked correctly haha. Nice. Money saving.

Hi etrailer, I can’t say enough. From the sales rep (informational and personable), to the super fast shipping (love the tracking system), to the help videos. The Curt hitch receiver fit my 2019 Cadillac xt5 perfectly. I also ordered a wiring harness and vehicle harness tester. All went smoothly. Would definitely recommend etrailer and thank you very much. A very pleasant experience.

2021 GMC Acadia
Easy to install. Great product. Haven’t tested it yet, but I’m sure it’ll work.
by: Brandon06/04/2022
Exactly as described. Instructions were clear and the item was plug and play. I was worried because I chose the cheaper option, but it didn't seem to make a difference. Doing it again, I would have bought the $5 tester to make sure because I won't know everything fully works until I need to use a trailor:)
by: Paul 06/22/2022
still works great after a year
by: 05/21/2021
The hitch arrived 1 month early than the scheduled date is which was a pleasant surprise. Although the box was destroyed and items ordered were there and were not damaged. The tow vehicle, a2021 Buick Envision, is a new vehicle the hitch did not that long to install. The wire harness harness was not. A dealership was contacted to install it. The instructions were not clear or explained what was needed. Only a cost of $xx.xx solved the problem.
The means of shipment, box or carrier, should be looked into. All items I needed were still in the box.
by: Ronald 09/11/2021
I struggled at first getting the plug out of the connector then I got smarter and watched your video. Easy when you know how. Your videos are great time saver. I recommend anyone installing to watch the video first. Very pleased with everything I purchased.

- Finding The Factory 4 Way Wiring Harness On 2021 Buick EnvisionThe Curt wiring harness # C56325 is designed to replace the factory 4-Way flat connector on the 2021 Buick Envision St models that came with a 4-Way connector from the factory. The factory harness should be located behind the rear bumper about in the center of the vehicle. I have linked the instructions and an install video of the same harness on a similar vehicle that should help you locate the connector.

I have added a link below to an installation video of this harness on an XT5, and at about the 2:30 mark you can see how our installer did it. What he did was slide the red tab away from the plug and up, and there will be a little gray tab to push down. I do highly recommend watching that...

You can check on your XT5 to see if it has the factory connector to plug the Curt harness into. The factory harness should be located behind the rear bumper about in the center of the vehicle.

view full answer... - Does Curt Trailer Wiring Harness Fit 2020 Acadia without Factory Tow PackageYes, the Curt wiring harness # C56325 does fit your 2020 GMC Acadia. You can verify by finding the connector behind your Acadia's muffler. If you don't already have a trailer hitch I recommend the Curt # C13293 because it's a much easier install than the other option for your SUV.
view full answer... - Best Trailer Hitch Receiver for 2020 Chevy BlazerThe best trailer hitch receiver for your 2020 Chevy Blazer is the Curt Trailer Hitch Receiver # C13418. The reason the Curt is the best is because it has a concealed crosstube which ensures only the receiver is showing, and is a much easier installation than the Draw-Tite model, which requires the removal of your Blazer's bumper beam; the Curt hitch does not. I have added a link to a video install for you to check out as well of the Curt Trailer Hitch Receiver # C13418. Additionally,...

- Does Rear Bumper of 2022 Buick Envision Remove to Install Curt HitchWe have had some feedback from customers who had installed the Curt hitch # C94ER on a 2022 Buick Envision and the consensus seems to be that the exhaust needs to lower for the hitch to fit past it. This would be easier than removing the rear bumper and is a pretty standard step for most hitch installs. It basically comes down to removing the hitch hangers which are rubber isolators that secure it to the vehicle and letting it hang a little lower.

This receiver hitch has a maximum gross trailer weight of 5,000 lbs and a maximum tongue weight of 750 lbs. This is the highest rated hitch receiver for the 2021 GMC Acadia. This fully welded trailer hitch receiver bolts onto your GMC Acadia's frame with no welding required. The powder coated steel is sturdy and corrosion resistant.

- Trailer Hitch Receiver for 2019 Cadillac XT5We have a few hitches that will work great for your 2019 Cadillac XT5. I recommend the Curt Trailer Hitch Receiver # C13285. This hitch has a gross towing weight capacity of 5,000 lbs and a tongue weight capacity of 750 lbs. If you plan on towing a trailer with this hitch you will also need a trailer wiring harness to operate your trailer lights. For that kit I recommend # 118276 or # C56325.

The Curt T-Connector Vehicle Wiring Harness # C56325 is confirmed to fit your 2022 Buick Envision and will plug into your vehicle's wiring harness, which is located behind your rear bumper on the driver's side. After installation the 4-way will be stowed under your vehicle by the hitch. I recommend using the No-Drill Mount # 18140 and the Mounting Bracket 4-Pole Flat # 18144 to mount the 4-way to your hitch to keep it from dragging on the ground and so that you...
view full answer... - Locating The Factory Connector For 4-Way Vehicle Harness On a 2022 Buick EnvisionThe factory connection on your 2022 Buick Envision is located behind the rear bumper cover. You will need to locate the wiring that comes out of the center of the body and follow the wiring toward the drivers side to the connector with the dummy plug(See Image). This is where you will be able to connect your Curt T-Connector Vehicle Wiring Harness # C56325 on your Envision. If your Envision does not have this connector you will need to use the Tekonsha Upgraded Modulite Vehicle Wiring...

- Comparing Curt and Draw-Tite Hitch for 2019 Chevy BlazerI highly recommend the Curt Trailer Hitch # C13418 for your 2019 Chevy Blazer, and this is the one I would put on mine over the Draw-Tite Trailer Hitch # 76023. The reason why I recommend the Curt is because it is far easier to install than the Draw-Tite hitch, which requires the temporary removal of fascia and the bumper beam, as well as trimming your Blazer's fascia. Another reason I would choose Curt over the Draw-Tite is because of the Curt's advantage in capacities. The Curt's...

- Parts Needed to Install 7-Way and Brake Controller in 2019 GMC Acadia w/o Tow PackageSince your 2019 GMC Acadia does not have the factory tow package you will need to first install a 4-way on your vehicle with the # C56325 and then convert it to a 7-way with the part # ETBC7 which comes with everything needed to also wire up a brake controller like the Brake EVN # TK63VR. I attached install videos for both wiring kits for you to check out as well that will walk you through the entire process.

I recommend going with the Curt Class III Receiver Hitch because it will be much easier to install than the Draw-Tite Class III Max Frame Receiver Hitch. The Draw-Tite Class III Max Frame Receiver Hitch requires that you remove the rear bumper fascia whereas the Curt Class III Receiver Hitch just requires that you lower...

- Will the Curt Trailer Hitch Receiver C13418 Fit a 2020 Chevrolet Blazer RSThe Curt Trailer Hitch Receiver part # C13418 is indeed a confirmed fit for a 2020 Chevrolet Blazer RS. In fact, I installed this hitch personally on a 2019 Chevrolet Blazer RS and there were no changes from the 2019 to 2020 model year so I know it works. I also confirmed this with Curt as well just as a precaution. If you will be towing then you will also need a trailer wiring harness, the Curt T-Connector Vehicle Wiring Harness part # C56325 if you need a 4-way or part # C56326 if you...
view full answer... - Best Trailer Hitch for a 2019 Chevy Blazer All Models Including RSThe best trailer hitch for a 2019 Chevrolet Blazer (All Models Including RS) is the Curt Trailer Hitch Receiver part # C13418. I place this over the Draw-Tite Max-Frame Trailer Hitch Receiver part # 76023 because it will be much easier to install. The Draw-Tite hitch requires removal of the entire rear bumper fascia which will take upwards of two hours whereas Curt hitch really just requires you to lower the exhaust a bit which will only take around forty minutes or so all said and done....
