When installing The Hopkins 7-Way Molded Trailer Wire Connector # HM20048 on your 1984 Chevrolet C/K Series Pickup the black 12 Volt hot lead will have to be used in order for the brakes to work. I have attached the wiring code below:

White Wire - Ground Usual Trailer Wire White
Black Wire - 12 Volt (Hot Lead) Usual Trailer Wire Black ( The black wire for a traditional brake controller that ports doesn't necessarily need to be active for it to work)
Green Wire - Tail Lights Usual Trailer Wire Brown
Brown Wire - Right Turn Usual Trailer Wire Green
Blue Wire - Brake Power Usual Trailer Wire Blue
Yellow Wire - Reverse Usual Trailer Wire Purple
Red Wire - Left Turn Usual Trailer Wire Yellow
