Feed two 10 gauge wires, one white and black, from the mounted brake control
to the battery area. Using a ring terminal, connect the black wire to the "AUX"
side of the 30 amp circuit breaker. Leave the white wire to be connected later.
Using a 10/12 gauge butt connector, attach the black wire from the "AUX" side
of the 30 amp circuit breaker to the brake control module’s black wire. Again
using a 10/12 gauge butt connector, attach the white wire from the battery area
to the module’s white wire.
