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.
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.

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.
On time. Good price. Great service. Thanks team!!

The electrical harness was seamless, totally worth the money, minutes to install. Would purchase again!
Nice quick delivery what i was looking for
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.
PLUG AND PLAY install...only 1 hole needed to be cut for the install...everything else is plug in and go.
Well made no more problems with the trailer lights
Super easy install, looks good
HArdest thing was to cut a hole in a brand new truck!! lol
Very easy install !
The ordering process was very simple. The videos on the how to install very helpful. And the actual installation was very easy.
Plugged right in and was perfect length

I'll give Amy a high-five and tell her it's from you, John! What kind of trailer are you towing?
This was the easiest installation I have ever had. Every thing was perfect.
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.

That's awesome! I'm happy to hear the installation videos came in handy for you Roman! Any upcoming adventures planned?
Exactly as advertised. Excellent fit.
It is exactly as described, great quality and easy to install.
Easy to install. No complaints here.
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
Excellent product and easy installation
Very easy installation
Easy to install and helps connect up our 5th wheel perfectly.
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.
