This wiring kit is the perfect pairing for the 2017 ford super duty and a gooseneck hitch. Very straightforward installation and no surprises. All plug ins are pre wired and just need to be plugged in. The aluminum body of these trucks mandates that the plug In needs to be attached with rubber mounts instead of screws because of dissimilar metals. Time will tell how well that works out.
Holding up quite well, decided to swap the self tapper style with some bolts and washers just for a better hold other than that works great
The installation video from etrailer.com was extremely helpful and provided exactly the information I needed to complete my turnover ball project. The wiring harness appears to be of high quality and has received strong recommendations from everyone I've consulted.
Very easy to install. Completely plug and play. I tried a different brand from my local O'Reilly but it was wired wrong. Returned it and ordered this one. Should have got this one first. No problems with this one and would recommend it to anyone. You will not go wrong.
You folks are just awesome. I ordered the part and it got here in about 4 days.
have not had the opportunity to install the replacement part yet but it was so easy to get the new piece and amy was very efficient is connecting me with the right part.

I'll give Amy a high-five and tell her it's from you, John! What kind of trailer are you towing?
Plugged right in and was perfect length
The ordering process was very simple. The videos on the how to install very helpful. And the actual installation was very easy.
HArdest thing was to cut a hole in a brand new truck!! lol
Very easy install !
Super easy install, looks good
Well made no more problems with the trailer lights
The Curt 7 pole wiring harness worked great. I had to order this part because the Bargman harness I ordered first did not work on my Ford F250.
Nice quick delivery what i was looking for
Work like a charm, easy to install instructions for great. Would definitely purchase again.

The electrical harness was seamless, totally worth the money, minutes to install. Would purchase again!
On time. Good price. Great service. Thanks team!!
It fit as it should with no problem. I actually didn’t end up mounting it into my bed. I had a OEM plastic storage area that I used for mounting the outer inside the bed.
PLUG AND PLAY install...only 1 hole needed to be cut for the install...everything else is plug in and go.
Good product well assembled
Part was exactly what I ordered. Installing it was easy

Working great, no issues
Great product, easy to install.
Great product and easy assembly.
Installed this in my 2021 F-150 long bed. Was able to cut a hole right by my onboard outlet in the bed of my truck. Simple plug and play install. On occasion the connection isn't the best, but I think it would be better if I used some dielectric grease on the connectors.

Great product. Plug and play mostly. I would be willing to spend a few more bucks if they sold it with the hole saw bit and the grease as a package deal. The plug is very easy to install. It helps to lowered the spare tire down to make room to make the connection, then all you have to do is cut a hole in the inside of the box, route the cord and mouth the outlet.

Great, no problems. Used quite regularly.
Perfect fit, easy installation
Only feedback I have is that one of the frame brackets where we had to press fit the bolt grommet was oversized and didn't retain the grommet. We worked around it to hold it in place until we could engage the bolt. Other than that we love the fit and finish and are very pleased.
