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

Loved this product. It helped me to add a seven pin trailer plug to my 4 pin plug on my Santa Fe 2021 without loosingmy 4 pin. You immediately get the brake light/tail light function for your 7 plug. For trailer electrical brake you will need to install a brake controller though Very! Very limited instruction was the the only downside. I used uhaul instalation videos on YouTube that were very helpful.

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.

Works just fine, installation was prety straight forward. A couple notes for those diy installers. The inputs to the 7 way are the old 4 way plug and then brake controller, power, ground, and reverse. If you already have a 4 way the power from that line is dead ended so instead of running a new power you can splice the 4 way. Also universal adapter - tow ready 118136 is highly recommended.

Gave it 4 stars because the mounting bracket is very thin and flimsy, will probably have to build a more solid bracket in the future.

Exactly 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..

My 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.

Ford couldn’t get a factory controller to work with my 2017 Expedition with tow prep package. I bought this and Hopkins brake controller with quick connect plug to my factory brake controller wire. Had everything installed and working out n 15 minutes. Plug the 4 way flat to 4 way flat tap ground to frame and splice brake wire together and 12v constant if you have to charge camper battery. Mount adapter. DONE

Received the Hopkins 47185 kit on time and in factory packaging. Nice that has both the 4 Pin and the 7 Pin Flat connectors. Just mounted the bracket and then place the connector unit into it with the supplied screws. The crimp connectors were already on each of the wires, so just matched the colors to the factory wires and crimped them on. Works great, put a little bit of grease on each pin and taped over each wire to seal moisture out.

Overall, this was a great purchase. 4 to 4/7 was exactly what I needed to upgrade my vehicle. I didnt use the mounting hardware but instead drilled out the bumper to have a more polished finish. It worked great.

Its all good, but I do have to hold onto the back of this plug when plugging in a trailer, or Ill bend the bracket back. The plug itself seems to work fine.
