Greater than one weekThis adapter is mediocre quality at best. The mounting bracket is thin metal that will flex. You will need to hold the adapter when you plug in your trailer harness. The supplied screws were small (10-32 perhaps). Large enough to work, but nothing more. The rubber cover over the four flat wire connector is also thin, I dont expect it to last very long. The biggest problem was the part that was supposed to plug into my existing flat four wire connector, would not. My truck had a Ford connector already and I wanted this adapter so I would not have to do as much wiring. But I had to cut off the connectors and solder the wires together because the Hopkins plug was made in a way that didnt allow it to plug into the Ford plug. The contacts are bright stainless, brass/copper contacts would be more durable. The Hopkins adapter will get the job done, but it is a much lower quality product than the Ford factory connector on my other truck.

> 3 dayThis item when I installed it looks and works great. We have a camper with a round 7 pin insert and waverunners on a trail with a flat 4 insert so this suits both well! The hardware that came with made the install a breeze and my wife was even impressed how nice it looks. Two words of warning though for us novices: 1) you have to ground the white wire even if you are hooking it up to an existing 4 flat connector. I drilled a small hole into my tow hitch underneath my car. 2) also when shipped the middle prong of the 7 pin adaptor is very tight- you need to separate the two clips to get your round 7 pin to fit correctly.

> 3 dayWorked great for over a year until the round cover broke off. There arent a lot of choices with the 7 and 4 prong plug ins. I bought it again. Will be very careful. I have a different brand one on my pickup. Its 25 years old. Hasnt broken. They dont make things to last anymore.

> 3 dayPlugs into an existing 4-flat for lights if you have one in place, or that connector can be cut off and the wires individually spliced. The other three wires, for brakes, back-up and 12v have to be spliced. It comes with butt splices. You have to know what you’re doing. If you have a vehicle that has separate trailer light wiring and a connector underneath, like GM trucks and Suburbans, you would be much better off getting a connector made to connect to your specific brand of vehicle, and avoid splices altogether.

> 3 dayExactly what I was looking for. I can plug in either type pigtail with no adapters required. I replaced my old 7 pin with this dual unit. You need to understand how your vehicle is wired if you have a brake power module. Make sure you unhook the battery during work and map out your wiring before you start. It makes it easier. The instructions provide color codes which are probably 90% correct based on most vehicles, but do not assume so. Get a tester and map the wiring before you start..

> 3 dayIronically, the 4-pin plug on this which is made to go into the vehicles 4-pin plug had rubber shielding around the metal terminals to create a seal. I installed this on an 03 F150 which also had said shielding. The two wont work together, only one end is to have this shielding or boot. But fear not as the fix is easy: I just took a utility knife and cut the rubber off the plug on this Hopkins unit. It then plugged into the truck fine. Otherwise, these are not of the most robust construction. Hopkins also sells a more heavy duty adapter under the Endurance line which is of better construction. Ive used both and will opt for the Endurance in the future. The Endurance is gray in color and has a raised X on the 7-pin cover.

Greater than one weekMy Explorer came with the standard 4 flat wire attachment. However, all wires necessary to complete the 7 pin connector are pulled right under the right rear tail light. I was able to tap into 2 of the additional 3 wires needed at this location. NOTE: I also put on a 2 receiver which required the removal of the rear bumper. This greatly simplified access to these wires, which terminate into a junction/connector. Even though Ford provides all the connections, the blue wire for the trailer controller appeared to be only 14-16AWG (unmarked) although it is fused for 30A. Since multiple internet sources recommended 12AWG minimum, I chose not to use the blue wire provided but to run a separate 12AWG line up to the battery and fuse it for 40A (circuit breaker actually). I actually ran a duplex (2wire) cable just in case. The two that I deemed useable were the orange (B+, aux power) which I soldered to the Black wire from the 7 pin; it(along with RT and LT) are fused at 40A which should be sufficient. I also used the Black w/green stripe (Reverse, BU) which I soldered to the Purple wire from the 7 pin. It is fused for 20A so shouldnt be any problems there either. I really like the way the manufacturer sealed this item, and maintaining the option of using either 4 or 7 pins is really nice.
