Hopkins Towing Solutions 47185 Multi-Tow 4 Flat to 7 Blade and 4 Flat Adapter

The ground pin on the 4-wire plug broke off even though its never been used. I installed this on my Ford van without too much trouble. I was able to get an adapter to plug right into the vans OEM trailer wire harness at the back of the van and plug the other end into the back of this adapter. I have to run the brake, 12V accessory and reverse light wires separately only because my van doesnt have those wires built into the tow package harness. The real downside to this adapter is the cheap manner in which it was made. The actual wiring side is fine. The plug itself is the issue. Its just really cheap and fimsy. The 4-wire connector broke off just by me removing the plastic cap a few times to test the wiring.

I installed a tow package on my Dodge Grand Caravan and needed the ability to connect a 7 round RV plug to my vehicle when towing my pop-up camper. This Hopkins 47185 Multi-Tow adapter was perfect for me because it allows you to easily have both the 7 round and 4 flat connections easily accessible. Everything necessary for the installation was included, and it took almost no time at all for me to install this device on my vehicle. I have used it multiple times since installing, and it has worked flawlessly. Highly recommend!

Quality

This 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.

This 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.

This is a solid adapter that will add a 7 round to your 4 flat plug. It takes a minimum of wiring, and the instructions are adequate, though I had to make use of some online resources. The materials are tough, and I am not afraid this will break at some point. The only reason that I subtracted stars was because the assembly of the adapter was not so great. The center screw on the front of the plug that holds the center wire in was practically falling out. It wasnt that noticeable, and so I spent a good deal of time trying to figure out why not all of my connections were being made.

On my particular car, there was no easy, inconspicuous, place to mount the bracket for this adaptor so I had to get inventive and make a special bracket to attach it to the car. Again, thats a design flaw of my car, not the unit itself which otherwise is excellent and works beautifully.

The 4-pin is not an add-on like other adapters. It is part of the adapter assembly. The wiring is accessibly, but firmly potted into the plug. Installed on a Subaru Outback with 4-pin factory hitch wiring. I had to pound the bracket flat and drill holes in braket to install, but it all worked out. It hangs a bit low for me, but I suspect it will be fine. Wiring all checked out fine with tester.

The item did not work. I replaced my old one with this new one to get the built in 4 plug connector. Pulled the boat to the water and none of the lights were working. Plugged in the old one and everything works. Something wrong with the internal wiring of the item.

Well made product, comes with a mounting bracket, which is not noted in the description. Wiring is easy, follows the standard 7 pin wire colors. The material is a hard plastic, instead of a rubberized plastic, which may be more prone to breaking in colder temperatures. Convenient 4 pin connector and 7 pin connector in one is a bonus. I would recommend this product to a friend.
