The 7-Way, on its own, will not engage electric brakes. You would need to add a brake controller. I would suggest a proportional unit as it will detect how hard you are braking in the truck and adjust the braking power on the trailer to match. It will yield a smoother braking system.
bona fide (not comparable) 1  In good faith. 2  Genuine; not counterfeit.
While some Latin phrases lose their literal meaning over centuries, this is not the case with bona fides; it is still widely used and interchangeable with its generally accepted modern day translation of good faith. It is an important concept within law, philosophy, and business.
