When it comes to the wiring for the Dexter Electric Over Hydraulic Brake Actuator, # K71-651:
1. The black wire will connect to the 12V circuit coming from the vehicle's trailer wiring that is always hot.
2. White is the ground.
3. The yellow wire will only supply power when the brake-away pin is pulled.
4. The blue wire carries voltage from the brake controller to the actuator. The difference in voltage affects the amount of braking force that the actuator pump will produce. Lower Voltage = Lower Braking Force, Higher Voltage = Higher Braking Force
