You won't have any problem with power going to the brake controller all the time. This lets the brake controller keep all of its settings and not lose them every time the vehicle is turned off.

Brake controllers are designed to enter a sleep mode after a period of time when there is no activity. An idle controller draws very little current and will not drain the vehicle battery.
