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

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

It was what it was described to be

This connector is the right one if you all ready have a trailer light connection.You only need to plug in your lights and run your wires for your brakes and 12v for camper . It has the optional wire for backup lights as well .It comes with a good bumper bracket and the necessary bolts , nuts and washers to get the job done . Once installed you have a connector for your boat or utility trailer or a plug for your camper or heavy pull trailer built into the same connection .

I had it for 4months now and no complaints it helps when I hook up trailer.

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.

Went to Alabama this weekend to pick up a trailer. Found out the trailer was a 7 blade plug. I only had 4 flat wiring. It plugged directly into my current wiring and then I just grounded it. Worked like a charm. 10 min install. Definitely recommend!

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

I havent hooked it up yet because a tester I bought shows the tail light is not working from the current adapter. I will be using this soon and believe I may have found a work around, otherwise it will fit just fine to the new trailer that I bought this for, I think the capped wires may be used for trailer braking which I dont plan on using at this time but nice to know its available.

If you need a 7 wire and 4 wire all in one, this will do the job. Been working fine in saltwater environment.
