Not a problem. You will need to attach the red brake controller wire to the green/yellow wire (vehicle stop lamp switch). This wire tells the brake controller that you are stepping on the brake pedal. It is a dedicated brake light only signal.

The green head lamp switch wire will not be used. It would normally be used for an illumination feature which most brake controllers do not have. Just tape it up and stow it out of the way.
