The blue brake controller wire runs from the truck to the brakes direct
The breakaway switch has two wires , both usually black , one will go to the fifth wheel side of the black charge wire in the 7 wire harness from truck to 5th , the other will go to the blue controller wire
When the breakaway is pulled it sends 12 vdc from the black charge wire to the blue elec brake wire , engaging the brakes fully , this needs to happen obviously when the 5th is not connected to the truck
Find the black charge wire at or near the battery
The battery disconnect has two connections on the back , one hot and one swiched- disconnected when turned off
Put the black charge wire on the hot post along with the cable from the bat , that way the breakaway will have power when the bat switch is off , also you will then get charge from the truck when the switch is off
