Product was a great factory fit for my 2022 GMC 2500hd. Install was straightforward. A little dielectric grease on the connections and zip ties to hold up the extra length and we were all set. The toughest part was trying to get the spare tire down to get more working room as the key fitting for the tire was corroded and had to use spray to loosen it up!



by:

Works great,took about an hour to install. The video is right, spare tire removal would have made it easier.

Thanks for sharing your personal experience -- nice to know what is really necessary :)



by:

Put this harness in in preparation for a fifth wheel. The only way this install would have been easier is if I had my son in law do it. Very easy install.



by:

Plug and play, worked as advertised, the cover plate works better than having the never needed 4 prong plug, should make them available at local distributors.
I already had a wye in my wiring harness with a wire that was meant to have a plug attached, I simply unplugged the factory wire and added this new harness, no need to disconnect the bumper plug.
GMC spent more money than I did supplying the harness and dummy socket, they should have just installed the working socket…oh well.
Good idea to use the grease to prevent corrosion.



by:

One year review - This harness has lived up to my expectations. You know it's quality-built when you don't need to think about it. When I hook up my fifth wheel to the truck, it simply works...every time. What else can I say? If you need this harness, you won't be disappointed.



by:

Simple Plug and Play installation. It really cant get any easier than this.
Quality parts as good as OEM



by:

Plug and play easy to install! The instructions included in the box and the YouTube video were very helpful. The hardest part was finding a place to zip tie the excess wiring. Took about an hour to install. Very pleased!

Used to to wire in my FourWheel Hawk camper on my new 2024 Chevrolet 2500hd, very easy to use and eliminates running wire from camper to truck battery. Since I converted my 12 volt batteries in camper to lithium, I do not tie them into truck battery.

Has been working for a year with no problems, use it to run the camper clearance and running lights. Also use the 12 volt supply to run refrigerator when traveling, plug it into lithium batteries when camping.

I added this wiring harness to the inside of my truck bed and couldn’t be happier. I have a fifth wheel RV so this addition kept me from having to run the RV’s cable over the tailgate.

Thank you very much for your gooseneck wiring, it fit beautifully. You guys need to call GMC and get ahold engineer and tell them what you're doing because they seem not to know anything about this wiring even the GMC dealership in Kalamazoo MI. Thank you.



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:

Shipping was fast, the etrailer video help give me the confidence to install myself. But to be honest the extension is well made and self explanatory to install. Works prefect.



by:

Super easy to install, and works perfec t.



by:

I took no more than an hour to completely install. The under the bed wiring was exactly as it needed to be to join in the wiring. It looks factory installed.

  • Best 5th Wheel Hitch For 2024 Chevy 2500 4dr Crew Cab With 6-3/4' Bed
    Hey Justin, I can definitely help with this. I do recommend going with a sliding 5th wheel hitch since your truck is not a long bed. The slider helps with clearance on tight turns. What I recommend is the B&W Companion OEM 5th Wheel Hitch w/ Slider # BWRVK3775. This is made specifically for the factory pucks in your Chevy, so installation is simple. The slider allows for 12" of front-to-back travel. Overall the B&W hitches are super solid. The head is fully articulating so you get smooth...

  • Recommended B&W Turnoverball Gooseneck Hitch for a 2022 GMC Sierra 3500
    No, I am sorry it will not. Your B&W item # BWGNRK1012 stops fitting the Sierra 3500's after 2019 when GM changed the frame size. For your 2022 GMC Sierra 3500 you will need the B&W Turnoverball Underbed Gooseneck Trailer Hitch item # BWGNRK1020. I have linked an installation video below to help you get it set up.

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. This system includes custom fit brackets that bolt into existing holes in your Sierra's frame. The only drilling you will need to do is in the bed when you add the holes for the receiver and the safety chains.

  • 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...
