NOTHING WRONG AT THIS TIME.ITS ALL GOOD I'M KEEPING IT 24V SO I WAS ADVISED IF A PERSON TAKES CARE OF IT AND REPLACE THE CORRECT PARTS.

Answer
Allen,


Not sure what kind of brake controller you are using. I recommend using the brake light switch for power to trailer brakes(brake applied)( White Black wire #913 on stop light switch under dash).


There is a ground bus bar under the dash, use that for the ground.

Get main power from orange wire going ot the stoplight switch.
