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

was not expecting it to be as heavy duty as it is ...great product

I love this adapter. Very affordable, and has many applications. I use the 7 pin connector on all my vehicles and trailers. But on the family farm almost every think still uses the 6 round, including the vehicles. Nowhere have I found a 5 pin round (vehicle end) to 7 pin blade (trailer). So I buy these and cut off the 4 pin flat (on the wire harness) and connect the wire harness to a 6 pin round vehicle connector. So now I have a 6 round to 7 blade and a bonus 4 pin flat adapter to plug into the farm vehicles so they can pull my trailers. I find that you can buy 7 blade to 4 flat, or 5 round, or 6 round adapter. But no one makes a 5 round to 7 bladed adapter. Surely Im not the one with this need..

I purchased this for an install of a tow package on my wifes 2011 Chevy Traverse. There really isnt any place to securely mount this on a 2011 Traverse. I had to fashion a 1/2 inch thick metal spacer to be able to use it. I dont recommend buying this for a Chevy Traverse as it wont work unless you have the ability to cut, drill and install a .5 thick piece of metal stock. It was a PITA but only took 20 minutes because my neighbor had a drill press and metal cutter. The product its self is well built and works. The supplied bracket is not overly sturdy and you must use caution when plugging in a trailer as it could easily be bent.

Good product.

Ive wired in a lot on a lot of cars the 7way is awesome for your camper and the 4 flat is nice to rent or if you have both stile trailers like me just back up plug in and hook up and go other then trying to find you 7 to 4 adapter you let a friend use so you got to buy anather and always use dielectricel grease on the wires and plugs and you will never have a problem with the ends by the way those 7 way to 4 flat adapters burn out this plug if kept up will last the life of a car

The 4 way plug was a nice feature. I didnt need to splice that connector in. I just used my existing trailer plug. I did have to make a new ground on the truck side, probably to handle the extra load from the trailer brakes and the aux power to the trailer. The mounting bracket seems a little flimsy. But it works. Use two hands to connect and disconnect and you should be fine. I like not having to use a 7 way to a 4 way adapter for my different trailers.

I trailer my racecar if I have to travel more than an hour or two to a track. I usually rent a truck (Ford F-150). The rental truck comes with a 4-pin connector for lights, but not for the electric brakes. This adapter (Hopkins 47185) allows me to connect my trailer and use the electric brakes. I purchased a Curt 56110 connector so I can just plug and play. Actually the Curt 56110 is for the lights only so I bought two Curt 56110 units and used the wiring & pins from one to modify the other to include the brake wiring. The truck has all the wiring, just not the final connector for the brakes. With this set-up I unplug the factory (lights only) connector at the rear of the truck (on chassis near spare tire) and plug in my modified connector and I do not have to splice any wires to use my trailer lights and electric brakes, and just unplug it when Im done.

Pretty good quality! It is great for the typical install, where you tow every-so-often... For professional use (plugging and unplugging daily) it would work okay for a decent amount of time but I worry that eventually the 4 screws holding the socket to the metal bracket would begin loosening, the plastic the socket is molded from is good not great. I like the layout of the receptacles. The metal bracket could stand to be a tad thicker, but it is good enough. The wires are generously sized, and I like the look of it on the vehicle. Would definitely recommend.

I added this to an old Ford Explorer that only had a factory flat-4 trailer wiring harness. Now I have the option of towing a trailer with the RV style 7-pin or an old school flat-4 plug in it. The flat-4 portion plugs directly into the existing flat-4 wiring on the vehicle so you dont have to cut anything off of the vehicle. The only thing you have to wire in is 12V auxiliary power and back-up lights, but only if you need them. Since my trailer does not use either of those options I just taped those wires up and left them there in case I want to wire them in later. It also comes with a mounting bracket and screws so mounting it is a piece of cake. I only had to drill two holes to mount the bracket. I would definitely buy again.

What arrived was exactly what I ordered. There is quite a price range on similar product and I went to the center as this is for my 1999 Dodge Durango that I use only to launch my boat. What I got was impressive for the price. Everything for a complete install was included (bracket, unit, wiring, screws, etc.) and the quality is good. I wasnt expecting the leads to be sealed (wax like substance to fight water/corrosion) and this is a bonus for guys like me (again, the Dodge stays at the lake snapped to the boat and is used to launch/retrieve the boat). Also, the leads at the other end (where the wiring connects to the tow vehicle) came pre-assembled with butt connectors already attached. Not only do you not have to supply the connectors to install (I know, not a huge expense but just to call it out), but what a snap to connect to your vehicle. Just put your tow vehicle wires in and crimp. Nice! The wiring is a quality grade and the bracket is sturdy. If you are price shopping and you choose this one, expect to get more than you paid for relatively speaking.
