Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness with 7-Pole Plug

by: Phillydb10/05/2016

The Curt Q20 with R20 slider hitch arrived just as promised in 3 days after placing the order. The Q20 head box was totally destroyed. The manufacture packaging was not made to ship individually using small package carrier such as UPS. Upon inspection I discovered that the bolts and washers were missing. I contacted Bill at E-trailer and told him. He explained that the replacements would have to come from the manufacturer and would take several days. I told him that I already scheduled an install and really needed those bolts and washers. He was able to round some up for me and shipped them out next day and they arrived on Monday just as promised. I also spoke with Bill about not being able to remove the head unit for the hitch. It needed to be removed to be able to install it on the slider. It seemed to be stuck and I could not budge it. I assumed that it may have been damaged in shipping, especially after receiving it in a demolished box. He explained to me that since it was new its tolerances were tight and I might try taking a pry bar to it. Well that did not make me feel real good. He was totally correct. Just a little more effort with a pry bar moved it just enough for the bushing to squeak loose and the head came right out. I am disappointed in the jaws on this unit. They look like they were forged by a 3rd grader. Not smooth and somewhat pitted. They are not machined jaws for sure. Had it all installed using the new Reese rail brackets for the 2017 F250. Everything went smooth. An added plus is the quiet ride when not connect to trailer. Can’t even notice the hitch is back there. My other hitch rattled and clanked all the time and was so annoying. I just hooked my 38ft 5th wheel for the first time. It was smoother and easier than any other hitch I have ever used. I bought the sider unit which is recommended by all for the short bed. However I cannot use the slider as the king pin box slides too close to the tall tail gate. The new 2017 F250 is taller and the bed is deeper so I needed a hitch that would go up to 19 ½ inches. I will update after a my first run with trailer later this month. Everyone at E-trailer was outstanding. 5 Star. I will keep using them in the future. 303440

It's actually long enough! 2014 Ram 2500 crew cab long bed w/factory hitch, and I installed this plug in the *front* corner of the bed. Have a truck camper, and its trailer plug is in the front left (driver's) corner. The cord is only about 2' long, so I needed to install a plug in the front of the truck bed. Before ordering, I measured from the factory plug at the trailer hitch over to the rear corner of the bed, then made a 90 degree turn and measured up the frame to the front of the bed. From there, took another 90 degree turn and went vertically to where the plug would hopefully be in the bed. About 12'. Since 10' is the longest I could find, I thought that perhaps I could run the cable more directly and shave off a few feet, and it ended up working. Far easier than custom building a wiring harness. The final installation route went across the top of the spare tire to the back of the fuel tank, then along the frame until reaching the front of the bed. From there, it traveled up to where the new plug is installed in the bed. There were plenty of points along the way to secure the cable with zipties so it's neat and tidy and not apt to get caught on anything like the rear suspension or spare tire. The cable ended up having a bit of extra length, not much, but a little ... I was glad it wasn't pulled taut! The install was simple and pretty painless. As others have noted, the zipties that come in the package are a bit too small to really be useful. 437034

Bought this harness for our new Ram 3500. The local RV repair place wanted $250.00 to splice into my truck's harness, but I elected to get this custom harness. Gave me an excuse to buy a hole saw, and after watching the video, I was able to successfully install the harness in a little less than an hour. The connections are solid, the cable was easy to route, and the end result is cosmetically and functionally excellent. The harness was long enough to be able to choose among several routing paths. I was happy that they included dielectric grease, and was also happy that I had a stash of self-tapping screws in my parts box, because one wasn't included in the product package. You need a self-tapping screw to attach the ground to the truck frame. This could result in a trip to the hardware store if you don't happen to have some sitting around. The other item you will need is some longer zip ties. The ones included in the package are small, suitable for tying to a small hose, another wiring bundle, or an existing frame mounting point, but having longer ties will make the job easier, especially if you need to get creative with routing. As always, great service from etrailer.com. It is a real pleasure to deal with these folks. 202738

No issues. Quality is excellent, hasnt shown any obvious signs of weathering.

I bought this harness a couple of months ago, but being winter, I am just now getting outside to install it. The item appears to work exactly as described. The instructions could be more detailed. For instance there is a white wire with a screw connection hole which was not mentioned at all in the instructions. I assumed it to be a ground wire and grounded it to the frame of my truck. But the 90 degree aspect of the harness is great. It let me put it in a tighter spot. It probably took me a total of less than an hour to install it. What instructions there were, were accurate and made it simple. I plugged our 5th wheel into the new outlet and all was good. Then plugged the 5th wheel into the outlet at the back of the truck where the original connection was. Also good. So I have an in bed connection for the 5th wheel and a below the tailgate connection for a bumper pull. Could not be happier. Well, actually, I am happier about something than the item. I am extremely happy about my dealings with Etrailer. It shipped almost instantly and arrived sooner than I could have imagined. As it turns out, I was not in a hurry (obviously), but I could have been. And if I had been, it would have been awesome to have gotten my item that quickly. Thanks guys/gals. 172847

I installed this plug and it was extremely easy and a very clean install. I wanted to use this unit because it did not require any splicing which can cause issues with the ITBC. It was only one 2-1/8 hole to drill and 4 self tapping screws and it was installed. I am very happy with this piece and would recommend it to anyone needing an in bed plug. 216893

Still working like day 1! No issues since install. Excellent product!

How good is free shipping, our Order was placed about 8pm est on Thursday Jan 19th, and arrived Jan 25th before I returned from work at 4pm. Just sold the F-150 I installed the previous B&W fifth wheel hide a ball hitch in. Love this hitch set up, after arriving at a campground and unhooking the camper I have FULL use of the truck bed. Install of round two begins in the morning, directions are simple and easy to understand. George J from E-trailer has been keeping me updated with information about my delivery status and made himself available had I had any questions. Wife and I have been camping for about four years, on our second RV and now our third truck and have been totally satisfied ordering everything we needed from E-trailer over that time, (about 18-20 orders to date) adding to the great products E-trailer provides is the HOW TO DIY videos on many products. 338589

Great product! Now we can plug in our RV and not have to worry that the cable is rubbing on the tailgate wearing away the paint. Our truck is a 2015 Chevy Silverado 2500 HD and we our going to be traveling 24/7 and now no worries about new paint being damaged by cable rubbing on tailgate while driving. 136700

The harness was exactly what I was looking for. Worked perfectly. The video provided on how to install was excellent. The product took longer to deliver than expected, however, I did not "raped" on the shipping and took the economical choice. 130363

No issue at all. Working fine as intended.

I found the wiring harness to be in good shape upon delivering . I would request that the company include a mounting bolt and nut for the white ground wire.Seems to work fine once installed on the truck . Shipping was super fast and well packaged. 96491

This wire harness was exactly what I was looking for. My GMC Sierra only had a bumper connection and this meant the cable from my 5th wheel RV hung over the tailgate and wasn't well contained. After watching the installation videos, the installation was straight forward. While waiting for the wiring harness to arrive, I purchased a hole saw and cut the hole in the side of the truck bed. Once the harness arrived, installation took about 30 minutes. It is now much handier to have the cable to the 5th wheel in the truck bed when connected. 232065

by: Aaron05/26/2016

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. 252037

Great product easy install plug n play. Installed on 2011 Chev 2500 hd to pull 5th wheel trailer plugged over tailgate when first bought but got extremely tight on turns and almost unplugged from truck installed in bed of truck no worries now would highly recommend. Great price also 20.00 dollars cheaper than RV store 133750

I assumed this would be a plug and play connector and go together seamlessly. However I found that the end connector that plugs into the factory harness does not lock appropriately. I made sure there were no bent pins. The locking clip and connector did not want to stay locked and I do not understand why. A 1/2 hour install turned into 2.5 hours which ended with ultimately using a zip tie to hold the two connectors together. I'll probably end up buying a another harness that will work. 130421

I wanted an in-the-bed electrical hookup for my 5th wheel rather than just hooking up to the plug on the back bumper. The Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness with 7-Pole Plug (41157) was just what I wanted for my Ram 2500. I watched an installation video. It simply plugged in to the existing wiring. I had to buy a hole saw for my drill. The plug looks good and works perfectly. I saved $80 over having it done professionally. 496621

by: Greg Ohrn09/14/2017

[another website] sent me twice, a 7 way plug and 3ft of wire for this part . I was running out of time and knew if I ordered this from e-trailer they would get it right! They got it right!! Shipping was fast as well as packaging. Thanks George!! This Pooduct was easy to install and works great! I like that the lid flips up 180 degrees. It also comes with the die-electric grease!! I used spray bedliner material around the hole to prevent rust! 432218

by: Bill12/08/2016

I had to replace the 7 pole plug. After a few months the plug started getting hot. Checked all the connections, all of the wires were secured. Went to local parts store and got a replacement. Same brand so far working very well. Not sure if I would buy online again. Because if I have a problem I can not wait for another plug to be shipped. So I am stuck not being able to use my trailer. I think Hopkins make good products. I just got a bad one. 323357

by: David O10/25/2016

This was really easy for not too mechanically inclined person. It really is a simple plug and play device. Just read the instructions or watch the installation video on e-trailer website. Visually verify that you are only drilling through a single panel if possible. Sometimes there is other sheet metal in there. Also have a quality metal hole saw on hand. Makes a lot smoother cut. All functions worked perfectly after installation. 310592

We just installed this last night on our truck. The instructions are easy to fallow. We will get our new 5th wheel next weekend so we will see then if they hold up. We love etrailer.com excellent customer service and fast shipping. Chris W thank you so much for taking care of our order so quick!!! We are working so hard on getting everything installed before we get our new 5th wheel!!! Your Amazing!! 420675

by: Mark G.10/26/2013

Product arrived quickly and in perfect condition. The harness took about 30 minutes to install from start to finish. Good quality and you really don't need the instructions because this is a plug and play part. I had to drill one hole with 2 1/8" hole saw to mount the plug receptacle using the supplied four self drilling screws to secure it then plug it in using the adapter and your done- Easy. 105287

This is a great brake harness for my new Dodge Ram 2500 truck making it easier to hook up the 5th. wheel trailer brake conector. All I can say is Shipping was excellent, quality is excellent, instructions were very easy to follow as well as a u-tube video. And last the price was awesome compared to others. I have to give ETRAILER a full thumbs up on this harnesse. 394381

I had a spray-in done on my truck, and was going to pay to have this installed at the same time. After watching the video on etrailer.com I decided to do it myself. What a waste of money that would have been! Total time was just under 10 mins, and was EXTREMELY simple. YOU GOT THIS. 121918

I had a plug on my 2015 Ram 3500 previously but it was stolen so all I had to do was plug and play this cord. Nope! The rear driver side tail light did not work. I called your customer service and they said my chassis ground was not good. I knew that wasn’t right so I purchased a Curt harness from the Ram dealer and it worked perfectly. 512278

Received the Hopkins wiring harness yesterday and installed it this afternoon. Any one could install this harness it is that easy. It took me longer to find my 2 1/8 inch hole saw than it took to install the harness. Just unplug factory harness and plug in new one and was done. As usual I received great service from etrailer. 140662

Plug and wiring were easy to install,just followed directions, entire project took less than one hour including tying up the wires and drilling the hole. Plugged trailer connector into both plugs and they worked just like they should. Probably one of the best and most reasonably priced kits on the market, I highly recommend! 297270

Very well satisfied with product, easy to install after watching video. Only down fall was the shipping, UPS delivered it to my hometown post office, instead of my house. Had to make a trip to town (12 miles) to get my parts, plus delayed installing them a couple of days. Otherwise very happy to have it inside the pickup box. 125176

Well thought out design on this product. Literal plug and play, just route it and secure the excess. I chose this one over the others they carry because the socket mounted to the bedside is replaceable separately should you snap the cover off etc. The cover opens 180 degrees too for a bit of extra visual when plugging in. 334467

I was a little skeptical when I ordered because I've ordered stuff on the internet before only to have it show up weeks later or even a call telling me a mistake was made and they didn't have the product but I have to say with etrailer I got my product fast and at a great price. I will definitely order from them again! 104935

This was the easiest trailer wiring I have ever done..Even though it was so simple to install, the finished job looks like a professional did it..

Good product - would recommend it. Need to take care picking where you place it - there are support beams under the bed that limit its location. Tried to squeeze it between the beam and the wheel well - clipped the edge of the inner liner but it worked. Also had issues with getting the trailer plug in - very tight. 136499

Problems from the start and and has not improved. Install was simple. Problems with trailer plugging into the outlet. More than one trailer with same result each time. Other trucks we have do not have any problems with the same trailers. To connect, usually have to force in with and will loose connection as we pull. 400459
