"Trailer Disconnected" Message

After wrestling with this intermittent message with two different trucks, I finally decided to do something about it. Actually, I was forced to because my trailer brakes stopped working at the start of my current trip. I had all of the lights and signals, just no brakes, and no way that I pushed and twisted the plug would get it to work. When inserting or removing the 7-way, I could feel no resistance at all between the contacts, so I knew the two plugs were not a good match. I found out about Pollak plugs on another site and how a lot of the Bargman plugs used by many trailer manufacturers were incompatible with many of the current trucks. I found a plug at a RV place in Hot Springs, swapped it out and have great contact, lights, and brakes.. Life is good again. May this will help someone who has been wrestling with this problem.
