If your brake controller is hardwired into the truck, then the connection on the red wire may need to be re-established. It needs to attach to the brake switch wire that only has power when the brake pedal is pressed.

If you test that red wire with a circuit tester such as # PTW2993 and there is no power on it when the brake pedal is pressed, then it is either attach to the wrong brake switch wire or the stop light or CHMSL fuse is blown and will need to be replaced.

Also, make sure the controller is not tilted or turned to one side because that can cause problems as well.

I have included some links on testing and troubleshooting brake controllers for you.
