Easy install. No instructions, but it's plug and play and everything is self explanatory.



by:

It does the job. I do find that the trailer light pigtail does not connect great. Sometimes it doesn't make a good firm connection and I have to fuss with it to get the trailer lights on.



by:

Item arrived on time. The online install video was very helpful and made the actual install very easy. The only challenge was figuring out where to zip tie the cord.



by:

This wiring harness has worked very good on my truck



by:

Easy installation as promised



by:

My new truck came with gooseneck towing package except the harness inside the bed. I ordered the Hopkins prewired trailering harness from etrailer. After seeing the instructional video I attempted to do myself. I discovered it was easy as advertised. The connectors stubbornly unclipped and clipped but all worked. I found the wiring length was well protected and the perfect length. I did notice on the 2020 Silverado had extra wiring so that the clip on the bumper did not need switching out. I also discovered I did not need to remove spare as the access of the wiring behind bumper was plenty. I stuck with the video instructions. Tested perfect and done. What I liked about the product was that it fit and matched the other factory components. Literally no tools required except to cut zip ties.



by:

This was easy to install and works grea t.



by:

Worked Excellent. Easy install. No longer need to run the cord over the tailgate, stays in the bed when connected to gooseneck hitch.

Fit in the factory location of my 2022 GMC Sierra pickup bed without modification. Easy installation and has been working fine ever since.



by:

Unfortunately it was not the right product for my 2022 gmc 3500hd. It did not fit the box factory cut out as in the video. It does work but not the product displayed in the videos.

It is unusual to hear that it did not fit into the factory cut out on your 2022 GM Sierra 3500. Would you be able to send a picture of how it fit in your truck bed.

David

5/24/2023

Here are a few of the pictures. It is my guess they probably just sent me the wrong piece.

The pictures really help and I am now closer to what may have happened. Did you receive part # HM40975 with this wiring kit?

David

5/24/2023

No, I did not.

Etrailer Expert

Jenny N.

5/24/2023

Yes, this makes more sense. The harness should have come with it and it is that connector that would fit into the cut out in the bed. I am asking our Customer Service team to review and reach out to you.

Easy 15 minute plug and play install in our 2022 Chevrolet Silverado 3500 LT and it works great!



by:
2021 GMCSierra 2500

The item itself is great. Plug and play, easy and quick install. The problem I had was etrailer failed to include the 4/7-way plug adapter that pops directly in the factory bed cutout (it is a separately packaged item included in this kit). I called them the next morning and they took care of getting it shipped out within the day. Problem is they shipped via usps and took almost one week to get to me. was looking forward to using it within that time frame, instead had to run the cable over my new truck’s tailgate… I believe that if a mistake is made it should be corrected as quickly as possible, not as cheaply as possible.



by:

Quick delivery and it worked for my tru ck.

  • In Bed Trailer Wiring For 2021 Chevrolet Silverado 2500HD
    You will actually be needing the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness # HM54FR for your 2021 Chevrolet Silverado 2500HD. This will ensure you have the correct wiring and length needed to install in your truck bedside. The # HM11141144 is for a Chevrolet Colorado.

  • Best 5th Wheel Hitch for 2022 Chevrolet 2500 w/ OEM Prep Package on 6-3/4' bed
    Since you have the 6-3/4' bed you will need a hitch that slides. I recommend the B&W Companion OEM 5th Wheel Hitch w/ Slider for Chevy/GMC Towing Prep Package # BWRVK3775. This hitch is made in the USA and has a quick, simple installation. It drops into the 4 receiver pucks that are built into your factory underbed rails. The built-in slider provides the clearance required for your short-bed pickup to turn safely at slow speeds and rail-free design allows for full access to your truck...

  • Recommended Gooseneck Trailer Hitch For a 2024 GMC Sierra 2500HD
    I recommend installing the B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1020 on your 2024 GMC Sierra 2500HD. This will fit both the short bed or long bed depending on your configuration. I prefer this hitch as the gooseneck ball stores inside the hitch and you have the ability to use an offset Ball # BWGNXA4085 and a Fixed # BWRVK3500 or Sliding # BWRVK3400 5th wheel hitch. The Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness # HM54FR will allow you to install...

  • How Much Weight Will The Demco Autoslide and Rails Add To a 2024 Chevy Silverado 2500?
    The Demco Autoslide 5th Wheel Trailer Hitch # DM8550034 itself is going to weigh 273lbs. The Rail Kit # DM39FR is going to weight 70lbs so you are looking at a total of 343lbs added to your 2024 Chevrolet Silverado 2500. I also recommend installing the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness # HM54FR which will add 3lbs. This will allow you to connect your trailer connector inside your bed rather than risking damage to the bumper connector stretching the wiring.

    To install the B&W Patriot 5th Wheel Trailer Hitch # BWRVK3255 in your 2022 Chevy Silverado 2500 8' bed without a prep package you just need to install some industry standard rails in the bed of your truck. For that you can use the Demco Hijacker Premier Series Above-Bed Base Rails # DM97VR. These rails are confirmed to fit your truck and will provide you with the industry standard rails you need to use your Patriot hitch. To make hooking up your 5th wheels wiring easier you can also add...

    The Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness w/ 7-Pole and 4-Pole Connector # HM54FR that you referenced does fit your 2020 Chevy Silverado 2500 and gives you the ability to install a 7-way/4-way in the bed of your truck. This plugs into the back of an active 7-way and allows you to put an additional 7-way in the bed of the truck via the longer harness that comes with it.

  • Will The Curt 7-Way Opening Cover Plate Fit a 2023 GMC Sierra 2500HD?
    Yes, the Curt 7-Way Opening Cover Plate # C29CR will fit your 2023 GMC Sierra 2500. This will allow you to install the Curt 5th Wheel/Gooseneck Custom Wiring Harness # C56070 into the factory cutout. We also have the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness # HM54FR which uses the factory style connector. This will provide a cleaner look in my opinion.

    First you will need the Curt EZr Double Lock Underbed Gooseneck Trailer Hitch # C65HR for your 2022 Chevrolet Silverado 2500. This will allow you to use the Curt X5 5th-Wheel Base Rail Adapter Plate # C16220 with your Curt Q20 5th Wheel Trailer Hitch # C16130 and retain your clean bed. The Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness # HM54FR will allow you to install the factory style 7-way in the bed for connecting your 5th wheel wiring.

  • Will The Bargman 5th Wheel/Gooseneck 90-Degree Wiring Harness # 50-97-410-010 Fit All Trucks?
    The Bargman 5th Wheel/Gooseneck 90-Degree Wiring Harness # 50-97-410-010 comes with aluminum mounting screws which are to be used on trucks with aluminum beds. This helps to prevent galvanic corrosion on the hardware. Beyond that it will fit on any truck which uses a USCAR style 7-way connector at the bumper. Several of the new Chevrolet/GMC trucks come with a cutout in the bed which will accept the push in style connector with the Hopkins Kit # HM54FR.

  • Hopkins Endurance HM54FR Tabs Will Not Engage Into Bed Side Causing Connector To Fall Out
    It sounds like the hole in the bed of your 2021 Chevrolet Silverado 2500 has to much bed liner material on the hole for the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness # HM54FR. This would cause the connector to not push in far enough for the clips to seat into the sides of the steel and hold the connector in place. You may need to sand down the excess bed liner material to get the connector clips to fully engage when you press it in.

  • Recommended Hitch System For a 2022 GMC Sierra 3500 Long Bed For Gooseneck and 5TH Wheel Towing
    I recommend adding the B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1020 to your 2022 GMC Sierra 3500. Currently no one is offering an aftermarket prep/puck system like the OEM for your Sierra. With the B&W you have the included gooseneck hitch ball that when removed will allow you to drop in a B&W Companion # BWRVK3500 5th wheel hitch. The Gooseneck ball will also fill the hole when flipped over to help keep debris out of the receiver tube. The Hopkins Endurance 5th Wheel/Gooseneck...

    The OEM prep package consists of 4 "pucks" in the bed of the truck that will allow you to drop in puck style hitches for easy installation and removal, that gives you a completely clear bed when not in use. The B&W Companion OEM 5th Wheel Hitch w/ Slider for Chevy/GMC Towing Prep Package # BWRVK3775 you were looking at has four puck style feet that drop into the pucks and a lever on each leg that simply turns to lock or unlock the leg in the puck.

I recommend installing the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness # HM54FR when you install the Turnover Ball. This will give you the same 4/7-way connector which fits in the cutout on the rear of your bed.
