Installation was very straight forward.
I used some left over pieces of foam pipe insulation over the cable where it passed over the truck frame and th inner wheel well. I mounted the extended Seven Pin connector just forward of the wheel well just below the bed rail on the driver's side.
The umbilical from our 5th wheel reaches with enough slack to lay on the truck bed.
We picked up our Escape 5.0TA two weeks ago and drove about 3300 miles from WA to MI.
The plug was easy to plug in and unplug.
Overall a very nice product.
Initially worked great, but now it keeps losing connection to the camper. I had to plug the camper in to the 7 way on the bumper to get home. Everything would seem fine but then getting on the highway I'd get a warning message on the dash and lose lights/trailer brakes. Not something you want happening at 70mph.
Truly happy with this product and can't wait to go to work! etrailer sent me everything I requested and the installer had no problems. Everything was packed well in shipping with no problems.
This product makes it so simple to add a Fifth wheel plug into the bed. Installation takes maybe 20-30 minutes. I installed mine on the column at the tailgate so it is out of the way (less likely to get damaged by other cargo). The only issue I experienced with install was that due to the small opening in that column (from under the vehicle), I had to remove the gray wire cover and then reinstall it after feeding the wire harness up into the column. (This was minor) Would definitely recommend this as it is simply "plug n play" with no cutting of wires or crimping needed.

Product and location has worked perfectly and keeps on doing so. Great product!
Very pleased with etrailer.com. All product information and reviews help make decision very easy. Very quick delivery and installation instructions are very easy to follow. Purchased 5th wheel hitch and custom wiring extension for my 2014 F250.

Thanks for the follow up. I’ve enjoyed the products ease of installation and use. I easily hook up my 5th wheel camper by myself and have had no issues. Great products!
Delivery was ahead of schedule. The product is top grade. I installed it myself which took all 45 minutes. Tested it on the trailer and everything worked perfectly.
The cord made the electrical part of installing my new fith wheel hitch very easy just plug in the connections and your done .

The products have worked flawlessly no problems and thank you for checking back with me its nice when a company cares about there costumers. Next time I need any trailer products I will definitely be contacting etrailer.
The trailer wiring extension worked perfectly for my 2013 2500HD setup. It was easy to install and makes hooking up and trailering that much easier.
Plug and play. Works great.
Nice long wiring harness.
Awesome product fit the truck just like it should and very easy to install keeps me from scratching the tailgate with a wire over the back of the truck easy to reach when hooking up trailer
Working very well yet!
Easy install and a great product. Used on 5th wheel rv trailer. No more wiring cord from trailer hanging over the end gate. Thanks!
Went on in minutes
Looks like an easy install good quality
Customer service for product selection and order entry were excellent and focused on my interests and needs. The hitch, custom installation kit, and harness were shipped very quickly and arrived sooner than expected. Everything arrived in excellent condition. Assembly and installation instructions were very clear and specific, and I was able to assemble and install everything with no problems and in a very reasonable amount of time. Total cost was roughly half of what it would have been if I had purchased the products and had them installed by a dealer. I am very satisfied with my experience dealing with etrailer.com, and would highly recommend them to anyone shopping for towing products.

Awesome. The hitch has worked great. Very, Very happy with the purchase,delivery, installation which I did myself, and performance of the product.Thanks again,Ill be sure to refer anyone who needs products you offer to you.
It worked exactly as it should. I did mess up on the hole location. I put it to hight and didn't allow for the depth. I had to make a 1/4" spacer to fill the gap.. my mistake.
I'm a huge fan of completing wiring projects with no "hacking" into harnesses. This harness is plug and play. When I finished installing it, the underside of the truck looks like it came from the factory. Job done

I havent thought about it for a year. I can give no higher praise for a product.it does its job very well.
Do not like anything to do with automotive wiring so I purchased this item because it appeared to be just plug and play with no cutting or splicing wires. It is just that, plug and play and it was done.
Unplugged 7 point connector attached to bumper and plugged in the new wiring harness. One other plug was unplugged and wiring harness 2nd plug was plugged in. Route wiring loom along along factory wiring loom inside frame close to the front of my 2004 F 250 super Duty 8ft truck bed. Drilled hole and connected harness and plug so my slide in camper electrical will plug into this trailer plug. Screws to mount to inside of truck bed are stainless steel which is great to protect against rust. I also brushed Rustoleum paint inside the hole I cut so there was no bare metal surfaces exposed. 10ft wiring loom was the right choice to get plug up near the front of my 8ft bed.
This wiring harness made adding a plug in the bed of the truck for the gooseneck trailer a breeze. I didn’t really need the 10’ harness but I just looped and zip tied the excess. One year later and the plug still works great.
Quality product with simple plug and play installation.
My 2019 Ram 3500 does not have the fifth wheel prep package. This (and Curt fifth wheel hitch rails / brackets also purchased) made it easy.
Have used this product since 10/2019...no problems in wet or (AZ) dry.
I haven't installed it yet, however, I cut the inside bed wall in preparation for a spray-in bed liner before installing.
It looks just like the picture and description, arrived undamaged and ready for install. Great installation instructions!

Still using and I really like the hitch and other items I purchased a year ago. After installing the Curt fifth wheel hitch, Ive used it several times and I will be using it a bunch over rbe next several weeks. Easy to maintain and use.
This is an easy install and seems well made. I probably didn’t need the 10’ long my truck called for but no problem zip tying up out of the way. Well pleased.
Worked perfect. Unfortunately 1 yr later at the bumper location (where the splitter is installed) I don't have reverse lights on my trailer. They still work from the new mount in the box, just not from the bumper location. It's possible it never worked from the beginning, as I didn't have a trailer with reverse light at the time, but I do now and they don't work... I understand I'm just outside of the 1yr warranty period too. My fault for not checking right away.
Works as advertised. This wiring harness is being used to connect from a 2019 Ram 3500 8' box to a slide in truck camper. I ran this harness across and then up through and over the drivers side wheel well to have the connector available in front of the wheel well and behind the fuel door. Plenty of space in the area between the box wall and truck wall without interfering with any of the fuel or breather lines.
