Wiring connections for the Electric Over Hydraulic Brake Actuator are as follows.

Yellow - Cold side of breakaway switch, The wire that goes hot when a breakaway occurs.
Black - Positive connection on breakaway switch, The wire that charges the breakaway battery.
Blue - Output from in cab controller, The wire that provides power from your brake controller.
White - Ground

The white ground wire will attach to the negative battery terminal on the trailer break away battery. The 12 volt power wire will connect to the positive battery terminal on the trailer break away battery. The 12 volt circuit from the 7-Way connector will also tap into the power wire on the unit. I have included a diagram from the instructions that should help.
