    The product is as described, easy to install and does the job. The mounting bracket it comes with is garbage and its surprising someone thought it would be acceptable to ship the product with it.

    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.

    Easy install and a quality product. The Dual connection option is a useful addition to my trailer towing ability. No need to have adapters floating around to lose or search for when a flat 4 wire plug is required. The plug was easy to install with the purchase of a wiring adapter needed for your particular vehicle. You MUST make a separate ground connection for this plug to work it does not piggyback the ground from the flat plug ground. Other than the additional ground the connection is easy and straight forward. Did not use the mounting bracket it was kind of light in strength I drilled a mounting hole in my bumper near the License plate to mount the plug. Better placement and protected from road hazards in this location. It is also illuminated at night by the License Plate Lights which makes for easier vision in the dark. ******************************************************************************************************* Used it to tow my boat and trailer (5000 lbs.)with disc surge brakes and reverse lock out relay from Cape Cod MA to SW Florida (1700 miles) and did not have a single problem it worked flawlessly.

    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.

    Very simple to use, when you have a plug in adapter.

    Plugs into an existing 4-flat for lights if you have one in place, or that connector can be cut off and the wires individually spliced. The other three wires, for brakes, back-up and 12v have to be spliced. It comes with butt splices. You have to know what you’re doing. If you have a vehicle that has separate trailer light wiring and a connector underneath, like GM trucks and Suburbans, you would be much better off getting a connector made to connect to your specific brand of vehicle, and avoid splices altogether.

    Perfect fit, works good. But 7 blade cap is flimsy plastic. Doesnt seem like it will last. Also the gauge wire for the battery lead a is the same as the lighting, not as heavy as the electric brake wire. I run a heavy gauge battery wire to the trailer so I can charge not only the break-away battery, but also an on board ( camping, hydraulics or accessory) full size battery. But good price and easy install
