Ordered this for a 2024 Silverado 2500HD even though it wasnt certain that it would be compatible. Once i figured the connections out the actual install took maybe 15 minutes! Ill add i coated all the connection pins with dielectric grease before reconnection. Worked perfectly.

The wiring harness was super easy to install. The instructions are easy to understand. I highly recommend this to anyone wanting to add a 7-Pole trailer connection to the inside of their bed.

2022 GMC Sierra 2500

Great Product!! Dealer wanted $200 to $300....Watched the accompanying video, and Installation was pretty straight forward on My 2022 GMC 2500HD. The only pain was getting at the Factory connection clip on the original plug... I chock that up to being my own fault for not dropping the spare tire down for ease of access...



by:

I liked this kit. It looks and feels like high quality. Installation was easy and it took very little time to get clean results. Etrailer was great to work with. I talked with Kim on the phone due to some questions that I had after I received my order. The call was professional and helpful. I would order from etrailer again.

2022 Chevrolet Silverado 2500

I was mad when I saw this, paid $200 to have installed in my previous truck’s bed. When I watched the video and saw it was plug and play I ordered and installed my self in less than 30 minutes. Shipping took a week but I won’t need it until the 3rd week of August when I head out with the fifth wheel. Product came as advertised with every thing needed to install. It looks factory (see pic). I am very happy with how it came out and the installation video was excellent.



by:

Amazing!! Fast delivery and no issued with items ordered. E- trailer is a great company!



by:

Just what I was needing for my 2022 Silverado 3500 HD. Worked perfect. Great accompanying videos to help with installation



by:

It was simple to install and worked great for a 12k mile summer trip.



by:
2023 GMC Sierra 3500

Worked with Neil on a GMC 2024. U known if adaptable with new GMC. Built my confidence as we spoke. Anyway, it did fit and works great with camper and boat. Made my own face plate to use the dummy hole on the driver's side. Extended my RV cord to fit. No holes drilled in bed. Would of worked better with the GMC factory fit plug but not the case. Excellent. It does work with the 2024 GMC.



by:
2021 GMC Sierra 2500

I love the setup but I have a concern that the connection in the bed once installed has a slight right angle into a sharp bed seam. It is at the spot right at the connector with no cable armor. I am concerned this will wear and cause a short down the line.

I would need to see your set up that you have under the vehicle. Can you please send me a picture of what you are concerned about?

Was perfect for what I needed.

Fast delivery. Haven’t installed it yet



by:
2023 Chevrolet Silverado 2500

Good instructions and simple to install.



by:

This was probably one of the fastest items to install on everything I have added to my 21 GMC Sierra 2500HD, Denali Duramax. The right angle plugs make it simply slip in, plug and play.



by:
2024 Chevrolet Silverado 2500

worked very well

2023 GMC Sierra 2500

Easy installation.



by:
2020 Chevrolet Silverado 2500

Outstanding!



by:
2022 Chevrolet Silverado 2500

This is what was ordered but not what was received. I received Item #C56070 which is the same without the plate. I will rate Item #C56070 separately but have to rate this middle of the road as this is not what was received. This would have been perfect if it was what was received originally.

DONE EVERYTHING YOU SAID YOU WOULD DO



by:
2023 GMC Sierra 2500

Great product that installs in minutes.



by:

Easy install and quality part. Works as indicated



by:
2022 Chevrolet Silverado 2500

Super easy installation. Works as adve rtised.



by:

This was plug and play so no issues. I would rather it not be screw down. But it works and looks pretty good.

Shipping was fast and product was very easy to install! Would definitely recommend.

Just what I expected. Quick delivery.

  • Recommended Truck Bed 7 Way for 2020 GMC Sierra 2500HD Denali
    Yes. You can use the Curt # C53CR that you were looking at and it will tee into the existing wiring to give you a 7 way connector in the truck bed of your 2020 GMC Sierra 2500HD Denali. This will keep the 7 way on your rear bumper operational as well in the event that it also needs to be used occasionally. I've linked a review and installation video of a similar harness that you can use as a guide during installation.

  • Best 2024 Chevy Silverado 2500 Gooseneck Hitch Recommendation
    I highly recommend the B&W Gooseneck hitch for your 2024 Chevy Silverado 2500, which is the following part: - B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1020 This is a custom fit hitch that allows you to store the hitch ball upside down when not in use, giving you a completely clear bed. The receiver is also squared which gives you a way to use one of the Companion 5th wheel hitches if the need ever arises. One other thing I recommend installing on your truck is an in-bed...

    To add a gooseneck hitch to your 2021 GMC Sierra 1500 Denali, I recommend the B&W Turnoverball Underbed Gooseneck Hitch item # BWGNRK1019. It fits all three bed lengths and the diesel models.

The only drilling you will need to do is in the bed when you add the holes for the receiver and the safety chains. Please note that if you have the CarbonPro box you can not install a gooseneck hitch. None...

  • 5th Wheel Base Rails & Custom Brackets For 2024 Chevy Silverado 2500HD
    Hi there Brad; good questions and let's start with the 5th wheel base rails, as you will need new ones to go with a custom, no-drill install kit for your 2024 Chevy Silverado 2500. The reason is you can't mix and match base rails and brackets, and I believe by "Pro" you are referring to old Pro Series rails, which there aren't brackets for. So for new rails and brackets the best option is the following: - B&W Custom Installation Kit w/ Base Rails # BWRVK2505 I like the B&W # BWRVK2505...
