## Customer Reviews

### ⭐⭐⭐⭐⭐ Works on many cars.
*by D***B on January 27, 2025*

This was installed on my Van and installation was super easy and instructions were very simple.

### ⭐⭐⭐⭐⭐ Easy to use
*by R***K on August 11, 2020*

Most new boat trailers require the five pin plugs and this one works for both 4-5 pin flat plugs

### ⭐⭐⭐⭐⭐ Makes transitioning my 7 pin connector to a 4 pin simple and painless!
*by Z***H on September 3, 2020*

This was a great solution. My vehicle is equipped with a 7 pin connector and I have a couple of trailers that only have a 4 pin connector. This makes it very easy to transition between the two.
