It sounds like the wiring on your trailer 7-way connector is wired incorrectly. Try using a circuit tester like part # PTW2993 and testing each pin on the trailer connector for function. If the pins on the connector are compared to the hands of the clock, the pin at the 1:00 position is the 12-volt accessory feed. This pin should show constant voltage. The pin in the 3:00 position should show voltage when the right turn signal and brake is activated. The pin in the 5:00 position carries the brake controller output voltage and should go hot when the manual brake switch is used on the brake controller. The 7:00 pin is the ground, 9:00 is left turn/brake and the 11:00 is the running lights.
If you determine that the vehicle trailer connector is wired incorrectly, examine the connector on the trailer itself and verify that it is correctly wired. You can use a car battery to power up each pin on the connector if needed to verify function.
I have linked an FAQ on wiring that shows the correct wire functions.
