Installation was very straight forward.
I used some left over pieces of foam pipe insulation over the cable where it passed over the truck frame and th inner wheel well. I mounted the extended Seven Pin connector just forward of the wheel well just below the bed rail on the driver's side.
The umbilical from our 5th wheel reaches with enough slack to lay on the truck bed.
We picked up our Escape 5.0TA two weeks ago and drove about 3300 miles from WA to MI.
The plug was easy to plug in and unplug.
Overall a very nice product.

Worked great, I traded the vehicle that I installed the wiring adapter in tho. So it may be of use to someone else also.
by: Spencer02/16/2024
Initially worked great, but now it keeps losing connection to the camper. I had to plug the camper in to the 7 way on the bumper to get home. Everything would seem fine but then getting on the highway I'd get a warning message on the dash and lose lights/trailer brakes. Not something you want happening at 70mph.

Truly happy with this product and can't wait to go to work! etrailer sent me everything I requested and the installer had no problems. Everything was packed well in shipping with no problems.

This product makes it so simple to add a Fifth wheel plug into the bed. Installation takes maybe 20-30 minutes. I installed mine on the column at the tailgate so it is out of the way (less likely to get damaged by other cargo). The only issue I experienced with install was that due to the small opening in that column (from under the vehicle), I had to remove the gray wire cover and then reinstall it after feeding the wire harness up into the column. (This was minor) Would definitely recommend this as it is simply "plug n play" with no cutting of wires or crimping needed.

Plug and play. Works great.

The trailer wiring extension worked perfectly for my 2013 2500HD setup. It was easy to install and makes hooking up and trailering that much easier.

Nice long wiring harness.

Awesome product fit the truck just like it should and very easy to install keeps me from scratching the tailgate with a wire over the back of the truck easy to reach when hooking up trailer

by: Peter C09/11/2016
Customer service for product selection and order entry were excellent and focused on my interests and needs. The hitch, custom installation kit, and harness were shipped very quickly and arrived sooner than expected. Everything arrived in excellent condition. Assembly and installation instructions were very clear and specific, and I was able to assemble and install everything with no problems and in a very reasonable amount of time. Total cost was roughly half of what it would have been if I had purchased the products and had them installed by a dealer. I am very satisfied with my experience dealing with etrailer.com, and would highly recommend them to anyone shopping for towing products.

I'm a huge fan of completing wiring projects with no "hacking" into harnesses. This harness is plug and play. When I finished installing it, the underside of the truck looks like it came from the factory. Job done

I haven't installed it yet, however, I cut the inside bed wall in preparation for a spray-in bed liner before installing.
It looks just like the picture and description, arrived undamaged and ready for install. Great installation instructions!

Still using and I really like the hitch and other items I purchased a year ago. After installing the Curt fifth wheel hitch, Ive used it several times and I will be using it a bunch over rbe next several weeks. Easy to maintain and use.

This is an easy install and seems well made. I probably didn’t need the 10’ long my truck called for but no problem zip tying up out of the way. Well pleased.
by: Adam 03/16/2021
This wiring harness made adding a plug in the bed of the truck for the gooseneck trailer a breeze. I didn’t really need the 10’ harness but I just looped and zip tied the excess. One year later and the plug still works great.

2004 Ford F-250 and F-350 Super Duty
Do not like anything to do with automotive wiring so I purchased this item because it appeared to be just plug and play with no cutting or splicing wires. It is just that, plug and play and it was done.
Unplugged 7 point connector attached to bumper and plugged in the new wiring harness. One other plug was unplugged and wiring harness 2nd plug was plugged in. Route wiring loom along along factory wiring loom inside frame close to the front of my 2004 F 250 super Duty 8ft truck bed. Drilled hole and connected harness and plug so my slide in camper electrical will plug into this trailer plug. Screws to mount to inside of truck bed are stainless steel which is great to protect against rust. I also brushed Rustoleum paint inside the hole I cut so there was no bare metal surfaces exposed. 10ft wiring loom was the right choice to get plug up near the front of my 8ft bed.

Quality product with simple plug and play installation.
My 2019 Ram 3500 does not have the fifth wheel prep package. This (and Curt fifth wheel hitch rails / brackets also purchased) made it easy.
Have used this product since 10/2019...no problems in wet or (AZ) dry.

- Recommended Camper Battery Charger for a 2015 Chevrolet Silverado 3500HD w/Factory Tow PackageIt sounds like you are trying to charge the batteries of your camper with the Silverado's 7-way trailer plug. As long as you wire the 7-way connectors the same function to function this will provide you with a maintenance charge for your slide in camper but it will not re-charge the batteries. If you need more than just a maintenance charge then I recommend a battery charger like the NOCO Genius Mini # 329-GENIUS5. This can connected to the campers batteries with the ring terminal attachment...

- Best 5th Wheel Hitch for 2022 Ram 2500 w/ 8' Bed and OEM Prep PackageI recommend the Curt Q20 5th Wheel Trailer Hitch for Ram Towing Prep Package # C16530-16021 for your 2022 Ram 2500 with OEM Prep Package. This hitch has a gross towing weight of 20,000 lbs and vertical load limit of 5,000 lbs. It also has a 2-Jaw locking system that provides a 360-degree jaw-to-king-pin contact for less rattle and more security than slide-bar models. The built-in cushioning absorbs road shock and has a 3-Point indicator system in which the color coding tells you if the...

The legs/feet are easier to see in the linked product description video. You might also want to install a 7-way trailer connector in the truck bed, so you won't have to run the trailer connector cable up over the tailgate. You can install an in-bed 7-way using part # C56000.
view full answer... - Recommended Gooseneck Hitch For A 2018 Ram 2500 With Short Bed And No Prep PackageTo get a gooseneck installed on your 2018 Ram 2500 with 6.5 foot bed, you will need the B&W Turnoverball Underbed Gooseneck Trailer Hitch w/ Custom Installation Kit - 30,000 lbs # BWGNRK1384. This is specifically designed for Rams without the prep package with or without a factory Air Suspension system. This is also made in the USA, so I am highly preferable to their products. One potential add-on to consider will be the Curt 5th Wheel/Gooseneck Wiring Harness # C56000. This can be added...
view full answer... - Compatibility of 5th Wheel Hitch with Tool Box/Transfer Tank in 2015 Ram 2500 Mega Cab 4X4You can compare the installation instructions for a sliding 5th wheel hitch to determine if there will be enough space for it along with the tool box/transfer tank you have installed in your 2015 Ram Mega Cab 2500 with 6-foot bed and no factory rail kit. With Curt base rail install kit # C16427-204 the position of the front-facing edge of the front base rail on a 6-foot bed will be 54-1/4-inches from the rear edge of the truck bed (not the tailgate) as shown in the linked diagram taken...

- Gooseneck/Fifth Wheel 7-Way Recommendation for Truck Bed of 2016 Ford F-250Yes, the Curt 7-Way Fifth Wheel/Gooseneck Harness part # C56000 would fit your 2016 Ford F-250 and would work well for you. I attached an install video for this kit for you to check out as well.
view full answer... - Availability of B&W 5th Wheel Hitch to Fit 2017 GMC Sierra 2500 with Factory Puck SystemYes, B&W does make a sliding 5th wheel hitch that directly fits into the factory 5th wheel puck system in your 2017 GMC Sierra 2500 with 6-1/2-foot bed. You can use their 20K-rated Companion hitch # BWRVK3770. It can be argued that B&W makes the finest 5th wheel hitches on the market. Completely USA-fabricated and assembled, the Companion boasts features like 12-inches of slider travel, beefy 1-inch-thick jaws that solidly grip your trailer king pin for little to no rattle, and a full-articulating...

This 5th wheel hitch will work well with a 5th Airborne Sidewinder like the Reese 5th Airborne Premium 5th Wheel Air Ride King Pin w/ Sidewinder and Turret # RP61422. The Rounded corners of the Shasta Phoenix 370FE is the turn point technology they refer to that will provide some turning clearance over the flat front, but a Sidewinder is the route to go for the...
view full answer... - Fifth Wheel Install Rail/Bracket Kit for 2013 Ram 2500Are you needing a Gooseneck Hitch which provides a 2-5/16 inch ball mounted in the truck bed, or a fifth wheel hitch which installs on rails mounted to the floor of the truck bed? The goosenck hitch rail kit you need will depend on which B&W, Reese or Curt gooseneck hitch you're using. If you could reply with that information, I'd be happy to make a recommendation. If you were looking for fifth wheel mounting brackets/rails, if the fifth wheel hitch you're using is compatible with industry...
view full answer... - Compatibility of Demco DM8550045 Recon 5th Wheel Hitch With Plate-Style Gooseneck HitchIt looks like you have a gooseneck hitch plate similar to the # C65500 we offer. The Demco # DM8550045 Recon Gooseneck to 5th Wheel Trailer Hitch Adapter you'd looked at would be an outstanding choice for your current setup, as long as the 5th wheel you tow doesn't have a rotating pin box like the Reese Sidewinder/Revolution or the Lippert Turning Point.. If you don't already have a 7-way trailer connector installed in the truck bed so you don't need to run the trailer connector wire...

- Availability of 7-Way Connector Shorter than 7 FeetI have some options for you, but unfortunately I could not find a 7-Way 5th wheel/gooseneck wiring Connector Loop shorter than the Draw-Tite # 20027. I recommend simply looping up any excess and wrapping a zip tie # DW05727-25 around it to adjust it to a shorter length. If your tow vehicle has a 7-way at the bumper that uses a US-Style car connector, another option is to install a 5th Wheel/Gooseneck Harness in line by using the Curt # C56000. This will provide you with a 7-way connection...
view full answer... - Will Curt A16 5th Wheel Hitch Sit Below Truck Rails on 2012 GMC Sierra 2500HDThe Curt A16 5th Wheel Trailer Hitch # C16621 you referenced in your question will work with your 2012 GMC Sierra. The height of this 5th Wheel Hitch can range between 17-1/2 inches to 21-1/2 inches. I did some research and found that the depth of the truck bed on your 2012 GMC Sierra is 21 inches. To be sure the hitch will fit under your Tonneau Cover when it is closed, you can measure from your truck bed floor to the underside of the Tonneau Cover. As long as this provides at least 22...
view full answer... - Reese 5th Wheel Outboard Brackets for 2020 Ram 1500 Short BedYes, the Reese Quick-Install Custom Outboard Brackets # RP56018 will fit your 2020 Ram 1500. Just make sure you have the Reese Universal Outboard Base Rails # RP30153 to match up with the design of the brackets. Both kits are available as a package with part # RP56018-53 on our site. If you don't already have a 5th wheel hitch you'll want one that has a sliding function so that your trailer will clear the cab of your Ram when you are taking tight turns. I really like the 18K B&W Patriot...
view full answer... - Which B&W Companion Hitch for 2016 Ford F-350 Long BedThe B&W BWRVK3405 is a replacement slider base, not a complete hitch. If you needed a replacement non-sliding base, you'd use part # BWRVB3500. You want to use a sliding hitch in a short bed truck to provide greater clearance between the cab and the front of the fifth wheel for low-speed turns, but a sliding hitch isn't necessary in a long bed truck because there's already plenty of clearance. If you needed the entire hitch, which includes the base and the hitch head, I'd recommend the...
view full answer... - 5th Wheel Hitch Compatible with Sidewinder King Pin for 2020 GMC Sierra 2500 with 6-1/2 BedI have a solution for you, but the B&W Companion Hitch # BWRVK3500-5W is designed to work on Ram Trucks. For your 2020 GMC 2500 Denali I recommend the B&W Companion Hitch # BWRVK3710 which will work in the factory puck system on 2020 GMC trucks. The B&W Companion hitches that connect to the 4 pucks in the factory towing package on trucks are compatible with Sidewinder pin boxes, whereas the Companion hitches that work with the B&W Turnoverball Gooseneck hitches will not work with a Sidewinder...

It is designed to plug in behind the bumper in line with your factory harness so you will still have full function on your existing plug.

I recommend the Curt Q20 fifth wheel hitch, part # C16541 as well as the # RP50054-58 installation kit. The Q20 features a fully articulating hitch head and a two piece jaw mechanism that holds the king pin very tightly, which provides good ride quality. The slider mechanism will give you 12" of travel. For...
view full answer... - Best 5th Wheel Hitch for a Lifted 2021 Ram 2500 With Factory Prep PackageWe have what is needed to make this work for you. Let's start by addressing the height, Please note the attached image. When towing you want your 5th wheel to be set level and you should have at least 5 to 6 inches between your rails and underside of the RV. Becuse your truck is raised several inches, you will want a hitch with a low height. I frequently recommend the same B&W Companion 5th Wheel Hitch for Ram with Towing Prep Package, # BWRVK3600 that you identified, as it is one of,...

- Will Both 7-Ways Be Active If Gooseneck/Fifth Wheel 7-Way 7-Way Kit was InstalledYes, if you install the Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector # C56000 both the 7-way at the rear of your truck and the 7-way in your truck bed would both be active.
view full answer... - Is Adapter Plate Needed for Towing Mor Ryde Pin Box Trailer with 5th Wheel Trailer Hitch To tow your 5th Wheel Trailer on your 2016 GMC Sierra 2500 with Factory Rail Kit, I recommend the Curt A16 Slider Hitch # C16521 along with adapter rails # C16023. The Demco Hijacker # DM6076P-UL-16K you referenced in your question is not compatible with the factory rail kit on your vehicle. The Curt A16 is a 16,000 lb capacity sliding trailer hitch with an interlocking 2-jaw system that will help create a quieter ride and the adapter rails are custom fit to work with the factory rails...

I was able to find the towing specs sheet for the 2011 Ford F-350 and its 5th wheel towing capacity can range from as low as 12,300 pounds (6.2L Engine, 3.73 Axle Ratio, Regular Cab, SRW, 4X4) to as high as 22,700 pounds (6.7L Turbo Diesel, 3.73 axle ratio, Regular Cab, DRW, 4X2) and numerous...

The correct 5th Airborne Sidewinder to replace a 1621 or 1621HD pin box is part # RP61422 that you referenced. This box also fits in place of several Fabex and M&M pin boxes. However, since it is rated for only 16K it will not have the necessary capacity for your trailer. We do offer the non-cushioned 20K-rated...

This kit is custom fit which saves time during installation and will work great with Reese 5th wheel hitches. It works with both the 6-1/2' and 8' beds. I have linked an installation video below. The Reese 5th Wheel Rail Adapter item # RP30154 you referenced is for the Ram factory puck package. There's no way to use this part on a Chevy Silverado....
view full answer... - Picking Between 7 Foot and 10 Foot Curt 5th Wheel/Gooseneck 7-Way Wiring KitIt really depends on where you would want to have the 7-way mounted in the bed of your 2022 Ram 3500. If you want it all the way up in the front of the bed I would go with the 10 foot part # C56000 but if plan is near the middle of the bed the 7-foot part # C56070 would be what you'd want.
