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.


Comments
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.

Arrived quick and installed it today. I bought the ten foot due to using it for a truck camper. Installed on my 2021 Chevy 3500 dually (8 foot bed). Easy to follow directions and I was able to run it all the way up the driver's side to the new location. Scariest part was cutting a hole into my brand new truck. I sprayed the hole with spray bed liner to coat the edges that were just cut. It comes with metal screws that I sprayed black also. Took about an hour to install.

This product was very easy to install and fit my 2020 Ram 2500 even though other sellers said it would only fit up to a 2018 or 2019 Ram. The price was also better than other large online sellers. I certainly recommend this if you're looking for a 5th wheel/gooseneck hitch 7 plug in bed outlet.


Comments
This harness is still working great.

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.


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

Product plugged right into the truck with no problems. Had extra long wiring cord. Didn’t have to worry about not having enough to place where I wanted it.

Very easy install on 2021 F250! All you need is a drill, a 2-1/8" hole saw, and a driver for self-tapping screws. Dropping the spare tire makes the job easier, but wasn't necessary.

Piece of cake install after reviewing some [online] videos. Approximately 1 hour to install. Did the install on a 2019, Dodge Ram, 2500, Bighorn. 2 1/8” hole bit did the trick for mounting in the bed, and dropped the spare tire to run the wire harness. Did come with dielectric grease for the connections!

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

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.

This brought my truck into the modern era when I installed this in the bed of my truck. This makes it a lot easier when hooking up the fifth wheel trailer.

Everything is fine and the vehical likes the way it is wired for the 5th and regular trailers.

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

Good kit, comes with grease and zip-ties, although the zip ties are very tiny ones and used my own larger ones.

so far so good, 5th wheel season is about to start again, we will see how year 2 goes.

Plug and play installation. Fishing the harness connector to the 2-1/8" hole in the bed sidewall was more challenging than indicated in the install video, but was eventually accomplished

Excellent product, installed quickly. Need to be careful when plugging the cables in, the pins may bend.


Comments
Still working great, use it about 1 every 2 months.

Plugs did not match vehicle, yes as listed correct part number too.


Comments
Thank you for your review. This should work on 1500 Silverados from 2003 to present and 2500 and 3500 Silverados from 1999 to present. Your vehicle should have the same connectors that are on the 44157 if you have a factory 7 way . If you do not have the factory tow package, you will need an ETBC7.

I just want to say that the customer service I have received from etrailer was second to none. I ordered a 90-degree wiring harness and when it arrived at our local post office we had a fire inside the building and everything was lost. I called etrailer and told them what happen and they started the process immediately to ship me another one. It arrived today. This is what we call Great customer service. I will send photos when I install it this weekend.

2020 Ford F-250 Super Duty

This is a great harness! I had my doubts because it was quite a bit cheaper than the others for my 2020 F250, but the quality is just as good as the other guys. everything plugged up to my factory harness and gave me another plug inside the bed for my 5th wheel. I gave it 5 stars because it was easy, everything you need ( - the hole saw and drill) Its plug and play, don't get no easier than this folks.

Been using this for a year now with no issues. Very easy install, I would use Dielectric grease when installing and make sure connections are good and you will have no issues out of this system.
