Review on Hopkins 48505 Blade Trailer Connector by Joel Miranda

All kinds of adapters are available to switch from seven to five to four blade connections. The problem is that with each adapter you add another potential point of failure. Directly, absolutely. If you need to connect power from your vehicle to different towed units with different blade configurations, have an auto electrician install a panel on the back of your vehicle with the necessary direct connect inputs that accept your existing plugs. I found this out the hard way: the five-to-seven adapter I had was flimsy and didn't make a solid connection to the seven-pin end of my truck's circuit. It drove me crazy Cutting this five-pin end off my van was a huge relief. I connected to this device and everything became fine immediately. Do not confuse with adapters. If you do that, sooner or later you will find out what I am talking about here.
