Fifth Wheel Trailer Connector

I have a 2011 Dodge Ram 2500 with factory brake cotroller and a 2011 Palomino Sabre. I am constantly getting a message on my dash "Tailer Brake Disconnected" The cable is tight, I still push in the connector as tight as I can. My message goes away. I drive about 30 minutes and get the same message and repeat the same process. Can I please have some thoughts? I'm driving dangerously and need help. Thanks.

Do you plug your cable in at the bumper or do you have a connection in the truck box.

I had that issue a few years ago with my old TT. I cleaned up the connectors with a small wire brush and put anti corrosive grease on both connectors. That seemed to take care of the issue.

You either have a bad ground, dirty/corroded socket or plug, or or a loose wire in the socket. My money is on a corroded/loose connection in either the socket or the plug of the wiring pigtail.

Use a socket/plug wire brush to polish them up. If that does not work, you will have to do some more troubleshooting. It is unsafe to drive with the indications you have. Most likely your trailer brakes are losing power.

Will clean your pins (WARNING - MAKE SURE THE POWER IS OFF) and the coat with a dielectric grease to prevent corrosion.

I had the same problem with my Rockwood 5th wheel. Kept losing connection, wiggle the plug and it would work again. Connections were all good. The problem, even though the trailer plug connected into the truck the electrical connections were just not a good match. I bought a Curt truck and trailer plug set, installed them and no more problems.

I use the dielectric grease on the connectors on my bike. It keeps them clean and prevents corrosion. I get a tube at NAPA for a few bucks
