Review on Reese Towpower 8536900 Professional Adapter by David Baer

Reliable adapter from 6-pin round to 4-pin flat. 3,500 miles on first use, through snow, rain and sun, with lots of disconnects and reconnects, no problem. I grew to like the turn signals over time, especially when the connector in our tow truck's wiring harness fell apart. I knew the signal was coming from the tractor. Will definitely buy again.
