Ever felt the dread of cutting into your truck’s wiring? With the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness, those days are over. This plug-and-play harness connects effortlessly to your factory wiring, maintaining the use of your factory-installed 7-way connector at the bumper. Not only does it make installation an absolute breeze, but it also spares your nerves and preserves your truck’s integrity.
Navigating tight spaces in your truck bed’s side rails can be tricky, but the innovative 90-degree angled connector design fits snugly into even the most confined areas. No more wrestling with awkward wiring positions; this specialized design caters perfectly to the compact spaces of your towing setup, making it ideal for fifth-wheel and gooseneck trailers.
When your towing setup faces the elements, durable materials and protective features make all the difference. This harness from Hopkins is constructed with internal seals, corrosion-resistant terminals, and rubber-coated copper wiring, offering excellent weatherproofing. It’s built to last through all seasons, ensuring your connection remains steadfast and reliable.
The installation process is often stalled by forgotten tools or missing parts. But with the Hopkins Endurance Wiring Harness, you get a complete set, including self-tapping screws, a dielectric grease packet, and nylon ties. It’s everything you need in one package, paving the way for a smooth setup without any detours to the hardware store.
Custom fit is crucial for a hassle-free towing experience, and this harness excels with a generous 10-foot length, allowing installation flexibility within your truck bed. Whether you need to install the connection near the tailgate or further up the bed, this harness gives you the freedom to choose the position that fits your towing habits best.
Switching to a fifth-wheel setup typically comes with the fear of losing your bumper's 7-way functionality, but not with this harness. It ingeniously retains the original 7-way plug, expanding your options without cutting any cords. It’s a smart solution that keeps your truck’s towing features fully operational, giving you the best of both worlds.

I have a fifth wheel camper that I pull with my 2006 Dodge Ram 2500. I was tired of draping the cord over my tailgate and having it get scuffed up. I bought this hoping that it would remedy the situation. Installation was easy and everything was plug and play. Tested after installing and everything worked perfectly.
Exactly what I needed. The Hopkins Endurance 5th Wheel 90-Degree Harness is truly plug 'n play. Once you decide on the truck bed location for the new 7-pole plug and drill the hole the rest is simply snap together and you're done. The new harness fit perfectly with the factory 7-pin connector and had plenty of length to allow for the new plug to be mounted conveniently in the truck bed wall. No more cable hanging out over the tailgate.

I have used the Hopkins Endurance 90-degree harness monthly over past year since installation. I have also used the factory bumper 7-pole plug as my towing needs required. Both connectors work every time indicating a solid fit and good contact between the factory 7-pin connector and the added Hopkins Endurance connector. Very pleased with both ease of installation and performance.
This is a great connector. I’ve purchased this before and installed it on my 2007 Ram 2500. It works great. I purchased another Ram truck a 2006 3500 and got this same connector again. The instal is simple and it provided a clean safe look to your setup.
Was easy to install and works great
This is great very easy to install
Installation went great drill hole and plug everything in comes with enough wire to put virtually anywhere in the bed. I was very pleased with the quality of the connectors.
Fits very nicely and is directly plug and play
Installed on my 2006 Dodge Ram 2500 in ten minutes. Works excellent! No more draping my wiring harness over my tailgate!
Really fast and great service. Ordered many things through them and never had any issues.
Works well. Defiantly better than installing a gooseneck under the bed hitch. You can swap the plate over to a fifth wheel plate with ease. 2 birds one stone. Defiantly recommend

Working great
Easy Install and fast Delivery. Plugged right right in.
Very easy install. Way too long of a harness for my needs.
Wrong one for my vehicle even though it said it was for it.
Return policy costed more to return than it was worth for a refund so I kept it and gave it away to my neighbor.
This harness was a breeze to install. Simple unplug and plug back together, cannot be any easier. Harness was plenty long to locate the plugin anywhere you would choose. Factory style connectors worked perfect. Highly recommend this product and would absolutely buy again. Thanks etrailer for your quality products and wealth of application/installation info available!!!

The T-Wiring Harness that is sold bye etrailer.com is the best one on the market, I wish I had taken pics or Video of my install! I have had NO Problems with this product! I think the hardest part was deciding where to mount the 7 pin plug in the bed of my truck, very very clean application and looks like factory install I am very pleased with this product. This product is going to for many many years to come best product on the market!!!!
Trailer plug can't come unplugged or drag the ground anymore with connection inside of bed.

Still works great
After using this plug adapter for a year I have been very satisfied. It was very easy to install, wiring plug was an exact fit. I use it for my fifth wheel travel trailer. I have not had any problems. Great product, thanks.
Perfect, easy install. Pu bed was wired for 5th wheel or gooseneck in l5 minutes.
Finally got the right part, my bad the first time, and the Hopkins wiring harness was in my 2006 Dodge Ram truck in less than 30 minutes. Most of your time will be spent drilling the hole in the side of the bed. I used a 2" hole saw vice the 2 & 1/8th (already had the 2" and didn't want to run out and buy another hole saw) and had no problems getting the harness through the hole. Hooked up the trailer and everything worked perfectly. There's plenty of harness, maybe too much, for any application in the truck bed. Great product!
The wiring harness for my gooseneck 7 pole hitch on my Dodge is as advertised. The only problem is I looked under my truck it is not wired with a stock connector. I will have to cut and splice it anyway. Not a problem with the product but with my wiring.
Wow what a fantastic experience! It first started when I called to verify I was buying the right 5th wheel wiring kit for my 2009 Dodge Ram 2500. Nicky K was the salesperson that helped me out, she took the time to verify my order and she placed the order for me at that point, I chose the two day delivery option and it arrived on time as she promised.
The endurance professional grade 5th wheel wiring kit part # 42137 was so easy that it took me only 45 minutes to install from start to finish, and most of that time was Running the wire from the bed location to the back of the truck where the factory 7 pin receiver is located. this kit is truly plug and play!! If I could do this in this amount of time and not have any problems then anyone can do it.
I would definitely recommend this company and this product to all my family and friends.
