Review: Converts 4 pin flat to 7 pin RV style - Just what I needed for my old Toyota Van. All of my personal trailers have been converted to the 7 pin round, whoever installed the wiring on my old van used a 4 pin flat that converts the independent turn signals at the plug. I couldn't just install a 7 pin without also ordering another converter. This fixed my issue. High quality, the trailer plugs all for perfectly and worked just like it was supposed to. I couldn't build this adapter for cheaper than they charged for it.
