Mount this 7-way, RV-style connector in your truck bed to simplify hookup of your 5th-wheel or gooseneck trailer. Harness plugs into existing wiring and retains use of factory 7-pole at the bumper. 90-Degree-angled connector fits into tight spaces.
Features:
Specs:
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.

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.
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.

Ive used this harness for 12 months and its great. I would definitely buy it again.
Product works great after a year or use connecting the fifth wheel trailer. Install went fast (hour or so), cable had enough slack to position and then some (remainder easily coiled in fender), and it came with everything needed including terminal grease.
Device was easy to install and functions as needed.

Install looks great, Shaun! Happy to hear that everything is holdin' up for ya.
Had to go with another brand from Ford. Couldn't get good brake voltage to the trailer. I could get power to the brakes but not the right amount for what the brake controller was set for. Tested by myself and a tech from a Ford dealer. It works but not good enough for my liking. Controller set at 8 only got a 6 reading at the 7 way plug.
First time i hooked it up the trailer plug was very loose fitting, a couple of good potholes driving through town and it was coming out and losing connection. I had to electrical tape it to the flap to be able to use without falling out. Nothing like drilling a hole in a 65k truck only to have the trailer brake plug not do the one thing its supposed to do.
This was not the solution I was looking for. I was really hoping to retain the OEM 12V input pigtail on my Lance camper, but Lance makes it impossible to DIY, there are no Lance dealers anywhere near me, and even if I had access to a Lance dealer their cost for such a basic job would have been unreasonably high. So after much hesitation I went ahead with this product. I cut off the Lance OEM plug, cut a big hole in the side of my pickup bed, and installed this harness. While this works fine for tail lights, brake lights, turn signals, etc., I had zero confidence the wire gauge was sufficient for charging my camper's internal 12V battery nor to run many internal 12V devices, so I ended up running a separate pair of 8AWG wires directly from the underhood battery to the camper's main service panel, using a 50A rated Anderson connector in the pickup bed. After a full year of service including approximately 6 weeks on the road, so far so good. I still haven't come across a better alternative, so I would do it this way again if I faced the same problem.
Fast, reasonable shipping. Item description said the harness was 10 feet long and it fit perfectly where I wanted to install it. Everything needed to install the kit came with the kit. High quality and worked correctly the first try.

A smooth installation project is always the goal! I am so happy this went well for you -- it looks great!
The item was exactly what I needed. Just be sure to fully plug in the other outlets. I had one that fit really tight and didn’t fully engage. Once I discovered it, everything worked perfectly.
Everything fit together exactly as expected. Had a lot of excess wire to coil. Need 2 1/8 hole saw for install. Plug n play otherwise.
A super easy plug in install. The harness is long enough to mount the plug almost anywhere you want inside your truck bed. There’s ample dielectric grease supplied but I did use different wire ties than those supplied because I wanted longer ties. I also used different fasteners because I was mounting into an aluminum bed. I opted for aluminum rivets.
The fit and ease of installation were very good
Wiring harness fit up great to 2022 Chevrolet 2500HD with Warner servicebed with bumper. Factory wiring harness was already there, so it was just plug and play.
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.
fast shipping and packaged nice.
I get no power to trailer connectors when harness is plugged in, hook factory harness up and connector has power.
I need to call and talk to someone, just have been very busy

Its worked well
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.

I have been using the connection for a year now and it has held about to a vigorous use. I remain satisfied with the product.
2024 F250 7.3 gasser. Hitch and plug fit perfectly. Exactly what I needed! A+++++++++
Easy to install but my first one was shipped in the same box as my fifth wheel hitch. Crushed upon delivery. Second one lasted a couple months before the internal wiring in one of the plugs went bad. I'm now on my third one in less than a year. We will see how long this one lasts
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.
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
Used this on a '96 F250, although not actually made for it. My '96 has the factory 7 pin plug on the bumper, but I wanted one in the bed. I un-soldered one of the connectors that is supposed to "Y" into the existing factory harness of newer trucks. I then soldered that connector onto the wires near my existing 7 pin plug on the bumper - now I have a "factory" connector! Anyway, after that the install was dead simple. I pulled a 5th wheel about 3k miles as well as shorter trailer journeys closer to home - no problem. I'd give it five stars if it was actually built for a '96.
If anyone has an older truck with an existing 7 pin plug on the bumper and wants one in the bed, this is a very good solution that can be made to fit with some soldering and electrical tap and/or shrink tubing.
Installation took 5 min. It was super quick and easy plug n play. Tested the trailer everything works.
Easy installation, great service

Works great does not get in line of fire when hauling landscape materials with or without hitch installed. Only hiccup Ive had was bumpy ride on freeway and a 2 hour slow moving traffic backup on the freeway. I had brake message trailer disconnected on dash of my 2012 Ram, pulled over to side of road. Looked at the contacts on both truck and trailer, got same message a few miles later. Pulling over again I plugged into factory bumper outlet, that lasted for the next 2.5 hours home. Now for the fix Using the brakes so much in traffic it had heated the trailer connector end enough to melt the plastic to blind over the brass contact. I scraped the brass contact with a pocket screwdriver to remove the fine layer of plastic off. So far it has worked perfect for 7,200 miles pulling my 5 wheel trailer.
