This T-connector wiring harness uses your factory tow package to add a 7-way socket in your truck bed while also retaining the use of the 7-way at your vehicle's bumper. The harness plugs into the back of your 7-way at the bumper and also into your factory wiring. And it provides 10 feet of cord to run the second 7-way connector to your truck bed. Installing a second 7-way connector in your truck bed makes it easy to connect the 7-way plug from your fifth-wheel or gooseneck trailer.

Installed on my truck bed for my Lance 650 coupled with Lance bed mount wiring harness purchased from another RV supply company to complete install and saved $600 from Lance dealer install. Also ran 2/8 gauge wires fused to truck battery hot and ground.



by:

Excellent product, fit perfectly where I wanted to mount it. Does not stick out when hauling landscape materials and lumber with 5th wheel hitch removed.



by:

This wiring harness is ideal for cutting in a trailer plug for your fifthwheel
I had it installed within an hour of delivery. Great job e-trailer!

The trailer wire bundle is a perfect fit and is like new after many connects this past year. I highly recommend.



by:

Just purchased a new to me 2020 Ram 3500. Surprisingly, this truck had no towing components other than just a receiver hitch. I ordered the B&W Turnoverball Underbed Gooseneck Trailer hitch and Hopkins wiring harness. Super easy to install yourself. I want to give Amy at etrailer a huge shout out for her excellent communication starting with the ordering process to final delivery. etrailer will definitely be be my go to source.



by:
Ford F-350 Super Duty

Received the harness just as described and on the same day as expected. Great product from etrailer! With minimal modifications, I will use the harness to connect my Lance truck camper to my F350 truck.



by:

Easy to install. If there one thing to note, it would be to add a caution in the instructions about drilling thru the inner bed wall. It will be easy to drill thru the inner wall to hit the outer wall, leaving a nasty dimple on the side of your truck. A drill stop should be used. I like to use tape wrapped around the drill bit and then around the hole saw. About 10 to 15 raps works.



by:
2023 Ford F-250 Super Duty

I've used one of these in the past with a Chevy and had no problems but my most recent one was either faulty or did not work with a Ford. The truck wouldn't recognize it at all so I had to order a factory replacement.



by:
2019 Chevrolet Silverado

The wiring harness was an easy install on my 2019 Chevy Silverado 2500HD LTZ Duramax diesel. Shipping was quick to the Pacific Northwest. The cord length is perfect for a custom placement. Looks like a factory installation with 100% positive tests when hooked up to the fifth wheel trailer.



by:
2018 Keystone Cougar Half-Ton Fifth Wheel

This was something I wanted to do for awhile and Now it's in and I couldn't be happier. The ease of pulling in the truck was awesome.

Installed this when I bought a truck camper. It was plug and play at the factory Ford end. I needed a 7-way at the front, driver's side of the bed for camper hookup. A little drilling and some hardware install and it works great at the front of the bed. I cracked the cover, no fault of Hopkins brand.

After a year, this product has been great. Worked as described and was plug and play at the rear factory Ford end.

Had this on my truck for a year now, still working perfectly. This is clearly a quality product.

Sales team and service was excellent. Product arrived on time and in excellent condition. Would recommend this company to anyone looking for anything to do with trailers.



by:
2014 Dodge Ram Pickup

I have a 14 Ram 6.7 without the convenient in bed plug-in for connecting my 5th feel connection. Always had to drape it over the tailgate.

A medium sized hole saw, some zip ties, and this harness did the trick



by:

Shorted every thing out now have no power to oem plug not happy!!!

That is not good at all! There are couple of things it could be. Do you have the camper connected and are trying to haul a trailer as well? It could also be that the wiring is bent or corroded somewhere on the new harness or the vehicles wiring.



by:
2023 Ford F-350 Super Duty

Everything works as stated. I'm very happy with the harness



by:

Easy installation, perfect fit. Completed install in 15 min!



by:

Simple install. Mounting socket seems built well and heavy duty.



by:
2019 Chevrolet Silverado 2500

My package was damaged in transit and the hitch ball was missing. Customer service was awesome and very quick to make it right.



by:

The install was very straightforward and the quality seems top notch. I'd recommend these products to anyone. I'll be purchasing a sidewinder pin box to complete this once our new fifth wheel arrives.



by:
2004 Chevrolet Silverado 2500

Great product. Installation time was ten to fifteen minutes even with cutting the hole in the box. This is an excellent kit overall. The zip ties that came with it were a little small, so I used my own. It would be nice if the kit came with the ground screw. I would recommend this product to anyone. I installed it on my 2004 Chevy 2500 HD.

The product is still working great a year later



by:

2013 Ford F250.
Easy install.
Installed
on side of bed.
Won't have to worry about tight turns and pulling on the plug or pulling it out. It was previously mounted on the under the bumper.
Everything went together smoothly.
All parts and accessories were in the box, didn't need anything extra.
Had the entire install done in about 20 minutes.

Thanks for a super product.

Always amazing service and products. Thanks to all the etrailer team.

Josh did a great job! I had a few questions and he was very knowledgeable. I had something that was on backorder and kept me in the loop. He has also sold me a set of Firestone air bags. I installed it alm this weekend and everything we talked about was correct. The bags reduced my sag and I am more than happy to tell all my friends about Josh and how he’s been my go to guy! Thanks!!!

  • Recommended 7-way and 4-way Connector For Bed Of 2016 GMC Sierra 2500 W/ Factory Tow Package
    To install a 7-way and 4-way connector in the bed of your 2016 GMC Sierra 2500 you will need the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness with 7-Pole Plug # 41157 which will plug in-between the connectors of your factory 7-way connector, but you will want to replace the included 7-way connector with the Hopkins Endurance Multi-Tow 7-Way RV and 4-Way Flat Trailer Connector - Vehicle End # HM40950. I included videos for each of the products mentioned for you to take...

  • Will Fixed B&W Companion 5th Wheel Hitch Fit in 2016 Chevy 3500 with Standard Bed
    Yes, the B&W # BWRVK3500 does fit your 2016 Chevy 3500HD even though it's a standard bed. Generally a standard bed uses a sliding hitch but if for one reason or another you don't need the extra turning clearance then a fixed hitch works just fine. You do need the underbed Turnoverball, part # BWGNRK1016-5W, if you don't already have it. Also, you'll want to add a wiring connector in your truck's bed with # 41157.

  • Troubleshooting 5th Wheel Trailer Wiring of 2017 Ford F-350 that Stopped Working
    The 5th wheel trailer wiring you have installed on your 2017 Ford F-350 is going to be like the # 41157 which only has two connections that you'll need to check. But since the rear 7-way is working that would indicate that the issue is the connection to the 7-way that's in the bed of your truck that's got an issue. Try unplugging it and firmly plugging it back in so that all of the pins seat firmly.

    You will need the B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1067 to fit your 2007 Chevrolet Silverado 2500HD Classic with a short bed. As you have a short bed you may opt for the 4" Offset Ball # BWGNXA4085. We also have the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness # 41157 which will allow you to add a 7-way connector inside your bed for the trailer to more easily connect and reducing the chance of damage to the harness.

  • Recommended 5th Wheel Hitch for 2020 Ram 2500 Short Bed With Factory Puck System
    We have a hitch that'll work perfectly with your 2020 Ram 2500. I'd recommend the B&W Companion, part # BWRVK3670. The Companion will drop right into the factory pucks (a slight one-time initial adjustment might be necessary). The thing that sets the Companion apart from other hitches is the jaw system. The Companion has massive 3/4 of an inch thick jaws that hold the 5th wheel king pin very securely for an excellent ride. The cam-action latching handle helps prevent binding making...

    B & W offers a high capacity 5th wheel hitch that will use the imbedded puck/under bed rail system on your 2014 Ram 3500, part # BWRVK3600. The hitch has a 25K capacity, and is the highest capacity hitch offered for your truck. The Reese Low-Profile 5th Wheel Hitch you referenced, part # RP30054 is meant for flat bed or cab and chassis trucks only, and would not be a good choice for your 2014 Ram with the OE prep package. I suppose if you were willing to go through enough modification...

You'd also want to install a 7-way trailer connector in your truck bed, part # 41157.

  • Custom 5th Wheel Installation Bracket Kit to Fit a 2015 Chevrolet Silverado 1500
    The fifth wheel install bracket kit # RP50026 fits specific Ford trucks so it's not the correct kit for your 2015 Chevy Silverado 1500. Instead you need part # RP50064 to fit your truck. If you also need the base rails part # RP50064-58 is the complete kit. I've linked a video of the install on a 2016 Silverado. If you already have Reese base rails you're going to use you should replace the hardware. Use hardware kit # RP58430. If you'd also like to add a trailer connector in your...

  • Recommended Gooseneck Hitch & Offset Ball for 2015 Chevrolet Silverado 3500 with 6-1/2-Foot Bed
    For your 2015 Chevrolet Silverado 3500 with 6-1/2-foot bed I recommend the USA-made option from B&W, gooseneck hitch # BWGNRK1012. I like this hitch for its high 7500-lb tongue weight (TW) and limited lifetime warranty. This B&W is about as good as it gets. No frame drilling is required to install the brackets; please refer to the linked install video for more. With it you can use their 4-inch offset ball # BWGNXA4085. If you need a wiring harness you can use part # 41157 from Hopkins.

    Great news! I know exactly what you're looking for. The product is called a 5th Wheel/Gooseneck Wiring Harness like the Hopkins # 41157. This harness plugs into existing wiring and retains use of factory 7-pole at the bumper. The Hopkins harness has a great 90-Degree-angled connector fits into tight spaces. I have linked the above mentioned product as well as an installation video of how it will install for your viewing and purchasing convenience.

    The RBW Lil' Rocker is compatible with industry standard rails, but you'll need to make sure the side to side and front to back spacing of the slots are compatible. If the slots are about 20-1/2 inches apart side to side (measured from the center to the center) and about 22 inches apart measured front to back, the M5 Series, part # RP30928, would work great with your existing rails.

  • Availability of Extension To Relocate 7-way Trailer Connector
    We don't offer a dedicated extension, but I have a couple of alternatives that can be used to do that for you. The least expensive option would be to use a 4-foot pigtail like # HM40985, but you'd need to cut off the factory round US CAR connector that's currently plugged into the rear of your 7-way and wire in the pigtail. The wire color function is shown on the linked product page. I'd recommend using heat shrink butt connectors like # DW05745-5 to protect the connections from moisture. An...

The hitch will come with 4 pins that you will use to secure to the rails. You will also need the custom fit wedge # SWW-06 that is used with B&W hitches and the Reese Revolution hitch.

The front tie-downs that are custom fit for your 2015 Chevy Silverado 2500 are Tork-Lift # TLC2220. The rear custom kit depends on a few details: If you have a dual rear wheel with no running boards and a factory hitch installed: # TLC3217.

If you have a long bed truck, a stationary hitch like the # RP30047 would be needed. If you have the short bed, you'd want to use the sliding version, part # RP30075.

If you would like the standard rails I recommend the Curt Custom Fifth Wheel Installation Kit # C16429-204 because it fits directly to existing holes in the frame of your Chevy, thus eliminating any drilling.
