- Red Wire: Connect to the cold side of the stoplight switch (voltage present only when the brake pedal is pressed).
- Blue Wire: Connect to the trailer brake wire at the 7-way trailer connector.
Setting Power to Trailer Brakes:
- Connect the trailer to the tow vehicle.
- Locate the Manual Slide Knob and Power Knob on the Brake Control.
- Apply the Manual Slide Knob and turn the Power Knob until the display reads 4.0.
- Drive at 25 mph on a dry, level surface and apply the Manual Slide Knob:
- If brakes lock up: Reduce the power setting.
- If braking is insufficient: Increase the power setting.

| Braking is weak or insufficient | Power set too low or poor connections | Increase power; check Blue wire. |
| Display shows "0.0" when activated | Poor trailer connection or wiring issue | Inspect trailer connector and wiring. |
Safety Notes:
- Disconnect the trailer plug before testing the breakaway switch. Failure to do so may damage the Brake Control.
- Regularly inspect trailer brakes and connections to ensure proper operation.
