Yes, the black wire goes to the number 4 terminal which is in the eleven o-clock position inside the 7-Way connector and is the 12 volt power lead. This wire should be wired to the positive battery terminal through a 40 amp Circuit Breaker, item # PK54540. The yellow wire goes to the number 7 terminal in the center of the 7-Way and is for auxillary power, or can be used for reverse lights. This wire will need to be wired accordingly. Use 10 gauge wire for these circuits.
