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.

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:

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.



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.

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.

Product was easy to install and works great. There was some conflicting shipping information that I was receiving. All in all, it worked out ok.

Exactly what needed and ordered. Fast shipping. Thank you!

Arrived the next day and I only selected basic shipping. This is the only company that seems to have what they sell in stock and ships quickly. Also if you have a problem they bend over backwards to make it right.

Excellent product.

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



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.

Good instructions and simple to install.

Was perfect for what I needed.

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?

  • 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.

  • 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...

  • Gooseneck Hitch for a 2021 GMC Sierra 1500
    To add a gooseneck hitch to your 2021 GMC Sierra 1500 you are going to want the Custom Underbed Installation Kit for B&W Companion 5W Hitch item # BWGNRK1019-5W. The underbed install kit gives you the gooseneck hitch plus the added option for a 5th wheel hitch if you ever need one. Please note this will not fit the carbon bed models. To make towing with a gooseneck easier I recommend adding the Curt 5th Wheel/Gooseneck Custom Wiring Harness item # C53CR. This harness puts a 7-way connector...

    In order to install an in-bed fifth wheel or gooseneck wiring harness on a 2023 Chevrolet Silverado 3500 you'll need the Curt 5th Wheel/Gooseneck Custom Wiring Harness part # C53CR which installs into the dummy plug inside the bed so there's no drilling or cutting and then simply plugs into the back of the trailer connector at the bumper. It doesn't matter what features or options the truck is equipped with, this harness works with all variations. I have attached an install video for...

  • Is Sliding B&W Companion Needed on 2022 Chevy Silverado 2500 w/ 6 Foot 9 Inch Bed w/o Puck System
    So the answer to your question is yes, for your 2022 Chevy Silverado 2500 with the 6 foot 9 inch standard bed, you will need the B&W Companion Slider # BWRVK3400-5W instead of the fixed B&W Companion # BWRVK3500-5W to safely execute a sharp turn without hitting the cab. The way I determined this is with the following clearance formula: (A + B) - C = Clearance (At least 4 inches of clearance is recommended to safely execute a 90 degree turn) A = Distance from center of fifth wheel hitch...

  • Best 5th Wheel Hitch for a 2021 Chevrolet Silverado 1500 with a 6-1/2' Bed
    The 5th wheel hitch I recommend for your 2021 Chevrolet Silverado 1500 with 6-1/2' bed is the Curt A20 5th Wheel Trailer Hitch w/ R20 Slider # C16541. This hitch uses the R20 slider which is needed for proper turning clearance in your short bed truck. The hitch has an interlocking 2-jaw system that provides a 360-degree jaw-to-king-pin contact to provide less rattle and more security than slide-bar models. This hitch has a 3-Point indicator system, the color coding tells you if the hitch...

  • Troubleshooting Left Hand Turn Signal Not Working On Curt 5TH Wheel Wiring Harness # C53CR
    I would start by disconnecting the Curt 5th Wheel/Gooseneck Custom Wiring Harness # C53CR so you will be able to verify the issue is with this and not either the wiring or a fuse on your truck. Since you mentioned that both connectors are not working I fear it may be a part of the trucks wiring or a damaged connector going into the trucks wiring. Once you have verified this please let me know what you find. Do note the harness has a 1-year warranty through Curt.

  • Recommended 5th Wheel Hitch for a 2022 GMC Sierra 2500 with 8' Bed and No Prep Package
    Absolutely, I can help you out with that. For your 2022 GMC Sierra 2500 with 8' bed and no prep package you will need both a set of rails and the 5th wheel hitch. The rails are going to be specific to your Sierra, for this I recommend the Curt Custom Fifth Wheel Installation Kit # C16429-204 which will provide you with industry standard rails in the bed of your truck. The industry standard rails will allow you to use the Curt A20 5th Wheel Trailer Hitch # C16140. This hitch has a limited...

    If you don't have the factory puck system in your 2020 Chevy Silverado 2500 with a 6-3/4 foot bed, you can still use the sliding Curt A20 5th Wheel Trailer Hitch # C55DR, but you will need to mount it on above-bed rails. For that you'll need the Curt Custom Fifth Wheel Installation Kit for Chevy/GMC Truck # C16429-204. These are the best option because they are a custom fit for your '20 Silverado 2500, and do not require any drilling into your frame rails to install. Not having to drill...

  • Recommended 5th Wheel Hitch for 2021 GMC Sierra 1500 with 5-3/4 Foot Bed
    Since your 2021 GMC Sierra 1500 has the short 5-3/4' bed I have a few options for a 5th wheel hitch and the difference really boils down to what you'd like to do or are willing to do. First things first though, we will need to get some rails and wiring installed in the bed of your truck and for that I recommend the Reese Rails # RP56015-53 and Wiring Kit # C53CR. Now that we have all of this squared away we can look at the different 5th wheel hitch options. I personally like the fixed...
