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.

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 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.
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

Hi Donald, We will be reaching out to help you get this taken care of.
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.
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.
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.
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.
It’s an easy install as long as you have a 1 1/8 to 1 1/4 hole saw. My only issue is that the harness is around 2ft too long and must be tied away.
Customer service was great! I call before I ordered online and they helped me get all the items I needed for my Fifth wheel hitch and electric!
fast shipping and packaged nice.
The Hitch was easy to install and is good quality. The box is was shipped in was torn up when it was delivered. i got lucky that nothing fell out
Purchased this to hook up a lance proprietary 6 pin to my truck, without splicing into the hard wiring. Raining outside... haven't installed yet.
Easy install. Have patience dealing with safety clips. Lowered spare tire helps. Beefier zip ties would work but great item
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.
Very easy install! 5 out of 5 for this kit.
It was bad out of the bag. I didn't notice it right away, but when I did I contacted Hopkins right away. They NEVER responded.
After some not always cooperative back and forth I think eTrailer made it right, but I haven't seen my refund credited yet.
Although the connectors on this cable plugged into the factory connections on my truck, there were two major problems. 1) My trailer cord didn’t fit properly into the receptacle. It wouldn’t retain the plug, and basically tended to spit it out. 2) It was apparently wired incorrectly, as the right turn signal pin was swapped with the brake control pin.
etrailer support was very accommodating. The agent provided a return label and steered me to a Curt assembly which I received within a couple of days. It fit perfectly, is obviously of much higher quality and I have had no problems with it whatsoever.
Excellent product. Easy installation.
Easy Install, spent more time gathering and putting away tools than actually doing the install. Wiring Harness is 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.
Product performs exactly as advertised and an easy installation.
Seamless installation.
Was a perfect plug and play connection. The only issue I had was at first I didn’t have the connectors tightly pushed together. My trailer lights were intermittent. Once I used channel locks and really squeezed the connection tight together it has worked perfectly.
The wiring harness fixed the issue I was having, left turn signal, left running lights and left brake lights working sporadically. Old harness had a short/ bad connection. Before buying new harness I tried cleaning the connections and looking for bare/frayed wires but still had same issue. Only issue with the new product is just the harness wasn’t available. I had to purchase a kit with parts I didn’t need to get the harness.
