Review on Hopkins 47345 4-Wire Flat Adapter: Enhanced SEO-Optimized Product Name by Gary Morris

I had a different adapter and was having trouble blowing one of the trailer light fuses and suspected wiring on my new trailer. It turned out that one of the diodes on the 7-to-4 adapter was shorted, resulting in a blown fuse in the truck. I now have both spare fuses for the truck trailer wiring and an extra 7 to 4 pin adapter. The great thing about this particular adapter is that it comes with LED indicators that show the truck's wiring is working properly and makes diagnosis easier. Great deal for the price.
