The electrique trailer brake must have functing brake controller and you need to run 10 AWG from the controller to the trailer plug and do you have 5 or 6 or 7 way plug on you vechile ?

Most common colour for North Américane electric brake is bleu and make sure you have ground conductor as well { white } to the vechile frame.

And many brake controller will have either fuse or circuit breaker { more common } at 30 amp rating.

What kind of vehicle you have ?? due many later models may have trailer harness ready all it have to is get the brake contoller circuit hook up.
