Are the taillights on your trailer LED's? If so, this could explain the issue you're experiencing. Ford and Chevy developed 'smart' trailer connectors over the last few model years that seem to be anything but smart. LED trailer lights can wreak havoc with these systems because of the very low power draw of LED lamps.
If this is the cause of your problem installing load resistors in the turn signal/brake lamp circuits of the trailer will increase the load on the circuit and solve the problem. We offer a pair of load resistors as part
