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.

I have had no issues with this harness. Every time I plug in a trailer it works just like Id expect.

Curt Wiring harness worked perfectly on my GMC. Good value and e-trailer has the best videos to help with purchasing the right product and installation.



by:
2025 Cadillac XT5

Very simple plug-n-play installation. Literally a 10-minute job. Push orange tab on car connector forward and depress tab hidden by that orange tab then pull out blanking plug from vehicle.



by:

Though not shown in the picture, the wires are protected by a flexible tubing. No wire to chafe.



by:

Was extremely easy to install. Worked perfectly. One recommendation is to install it before you install the trailer hitch. That way you have plenty of room to work with the connector.



by:

This item was a perfect fit and worked great. But, when I had a new hitch installed, the installer put in all new wiring...sooo....good product while I needed it :p



by:

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.



by:

AS ALWAYS THE PARTS WERE PERFECT BUT AS YOU CAN SEE I AM ONLY GIVING 3 STARS. THIS WAS ORDERED FOR A CUSTOMER, DELIVERY WAS SLATED FOR WEDNESDAY AND WE SCHEDULED A THURSDAY INSTALLATION FOR OUR CUSTOMER WHO WAS LEAVING ON VACATION SATURDAY EARLY MORNING. WHEN THE PARTS DID NOT ARRIVE AS PROMISED I CALLED CUSTOMER SERVICE AND WAS TOLD THE DELIVERY WAS DELAYED. I ASKED WHEN I COULD EXPECT DELIVERY AND HE SUGGESTED I CALL UPS BECAUSE HE HAD NO IDEA ??!!? A VERY GOOD CUSTOMER DELAYED HIS VACATION UNTIL SATURDAY AFTERNOON BECAUSE I LET HIM DOWN. AGAIN THE PARTS WERE PERFECT AND WORKED GREAT, YOU JUST NEED A LITTLE TRAINING FOR THE CUSTOMER SERVICE PEOPLE

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.



by:

Survived being shipped in the big hitch box and installed smoothly and easily.



by:
2018 GMC Acadia

Very handy and makes a nice inatall. The instructions are vague and incomplete. They do not tell you exactly how to release the OEM connector plug, only that you push the red lock up. Then what? Press where? It took 15 minutes to fugure that out or fear of breaking something. (Ask me how I know!)



by:

More difficult to install than expected. Longer bolts would have helped. Fine after installation.



by:

Fast delivery, good customer service. The installation video on the website could have shown a little more detail on how to remove the car's weather cap.



by:

Delivery was fast and on time as promised! Installation videos and instructions were spot on. Would highly recommend!



by:
2017 Cadillac XT5

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!!!

Product was easy to install and works w ell.

The hitch fit perfect and did not have to drop the muffler it slid in between the bumper cover and muffler with no problems. Great product.



by:

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.



by:

It took a little longer to install than stated however I think I could install another one quicker the second time. Seems to be a good quality product and it's made in the USA!



by:

Plug in design made it easy to install. Video also were a big help.



by:

It’s my 2nd order from etrailer and like the first one top notch products, videos, instructions, quick to ship, and excellent customer service!!



by:

Once again, very easy to remove and install new plug. Nice to have the YouTube video to instruct how to disconnect the plug.



by:

Great product and video showing how to install on specific vehicle. Went on as shown, with no difficulty at all.



by:

Works just fine, installation was easy as I installed it during the hitch installation and didn't have any issues.

2017 GMC Acadia

Super easy plug and play connection.

  • Recommended Trailer Hitch Receiver For A 2024 Buick Envision
    Hey Michele, Yes, there were no design changes to the 2024 models so the Curt Trailer Hitch Receiver # C94NR would still be a compatible fit for your 2024 Buick Envision. If you need trailer wiring as well then you would want the Curt T-Connector Vehicle Wiring Harness # C56325 as well.

  • Troubleshooting Trailer Tail Lights Not Working When 2020 Blazer Headlights Are Turned On
    First I recommend testing the 4-way on a different trailer otherwise you could use a Tester # I26 or Test Light # PTW2993 to verify the issue is not with the Curt 4-Way # C56325 or your 2020 Chevrolet Blazer. If you have verified the issue does not repeat itself on another trailer or with a tester then the issue is most likely related to a ground issue. It may be the ground connection from the trailer to the trailers 4-way is not making good contact and is causing your issue. Please...

It has a 2,000 lbs towing capacity and a 200 lbs maximum tongue weight.

  • How Much Can I Tow With A 2021 Chevy Blazer
    Yes, you can absolutely pull a 1500 lb trailer with a 2021 Chevy Blazer. Looking at the online owners manual for the Blazer it looks like there is some variance in towing capacity across different models. For example, Blazer 3LT and Premier trims are capable of towing up to 4,500 lbs with the available Trailering Package in combination with the 3.6L V6 engine and available AWD. Please refer to your owners manual for specifics on your vehicles towing capacities. That said, if you need...

  • Recommended Trailer Hitch For A 2023 GMC Acadia With Wiring and Ball Mount
    Hello MJ, We can definitely get you set up with a hitch. For your 2023 GMC Acadia you will want the etrailer Trailer Hitch Receiver - Custom Fit - Matte Black Finish - Class III - 2" # e36AR. Great thing about our etrailer hitch is that it comes in a matte black finish which I think gives it that OEM look. If you are looking to tow something without brakes, or using a hitch mounted accessory that needs a 4 flat connector, you want the # C56325. If you are looking to tow something a little...

    Yes, 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.

  • Best Trailer Hitch Receiver for 2020 Chevy Blazer
    The 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 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...
