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

This install was not easy! Unless you have the capability to wire test or have the wire color diagram for your vehicle, its nearly impossible to install this with any accuracy. The manufacturers website and instructions that came with the product are not much help either. I spent 45 mins looking for my vehicles wire color designation for the trailer wiring harness and only found some guys description of the colors for my 2005 Suburban, which was dead on and made the install happen. Im very surprised that my super common vehicle was not easily found online. I also had to snip off the white ground connection so I could connect to my vehicles ground wire and not attach it to a metal spot on the vehicle, like the manufacturer suggests. I also had to cut off the 4 way connection it came with since I didnt have one already present on my vehicle. This also forced me to go purchase several new connectors to complete the install. In the end, my black vehicle wire connected to the new white harness wire, the red vehicle wire to the purple harness wire (the rest matched color for color except the dark green). As one may imagine, its any wonder why one wouldnt be able to use the harness for an easy install.

This product will do what is says it will do. That being said, it does not inspire confidence in heavy use situations. It does not appear very rugged. Nice that it comes with the mount, but again the mount is very thin and light and probably wont last very long. Also, the wire coloring does not match with the standard US codes. White is ground on the item, while in most cases in the US, black is the ground wire. Where was this thing made? Again, it is a good price, and a useful product, but just beware it might be very rugged or reliable. Make sure to read the enclosed documentation so that you match your wiring correctly.

The hardest part is found the wiring diagram for LR3 but it work, just follow booth diagrams and its gonna take around 25 min.

This connector is amazing. I originally bought the Hopkins 7 blade trailer connector from my local tractor supply store. JUST the 7 blade, and it costed me $30. This is the 7 blade and 4 pin for just $14 how can you beat that? Everything is quality. Mounting is very easy and pre-drilling 2 holes is required. The only thing I have to say about this that was kind of workful was the wiring, but I cant take away a star because this thing is universal for many vehicles. I have a 2005 Tacoma and the only wires that color code matched were black, white, and blue. I had to expose the rest of the wires and match them by hooking up to a trailer and testing the blinkers and brakes to the corresponding wires. This was very easy with another person helping, it took me about 5 minutes. Overall I highly, highly recommend this product to anyone in need of a new trailer connector.

Easy install on 95’ ram 2500 I already had 4 pin flat connector installed. So mounted the bracket to the receiver hitch and plugged it into my stock 4 pin and now I have both 7 pin and 4 pin flat. And they both have dust caps which is helpful for maintaining clean connectors

Used it to add a 7 pin connection to 2008 Ford Expedition that came w/ the 4 pin connection. Mine had electric brake pre-wired, but no power line (black). I was able to make holes on the 4 pin connector holder and attach this adapter using nut/bolt. The wires behind the 7 pin connection touch the spare tire a bit, but I was able to install everything w/o much trouble. Looks professional, and so far no issues connecting/hauling a travel trailer.

Good product bought to go with a brake controller as upgrade to factory wiring.

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.

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.

Installed and hooked this up on the back of my old d350 just had to plug in my flat plug for lights and add my trailer brakes
