- C. Anchor and Pivot Holes
- D. Two-Digit Power Display
- E. Optional Ball Mount Interface
Tools Required:
- Phillips Screwdriver
- Drill (Optional)
- Standard Adjusting Tool or Screwdriver
Important Notes:
- Do not mount or activate RF-generating devices (e.g., cell phones, radios) within 12 inches of the Brake Control.
- CAUTION: Reversing the connection to a breakaway battery on the trailer will destroy the Brake Control.
- Always disconnect the trailer plug before testing a breakaway switch to prevent damage to the Brake Control.
- WARNING: Ensure that the Gross Combined Weight Rating (GCWR) never exceeds the vehicle manufacturer’s recommendation.
- The Brake Control is specifically designed for use with electric trailer brakes.
Installation Steps:
Step 1: Mounting the Brake Control
- Select a solid surface under the dashboard for installation.
- Secure the mounting bracket using the provided #6 x 3/8" screws.
- Insert screws into the mounting holes (C) and adjust the Brake Control to the desired position.
- Tighten screws until snug.
Step 2: Connect the Wiring
- Connect the White Wire to the vehicle’s ground.
- Connect the Black Wire to the vehicle’s battery.
- Connect the Red Wire to the brake signal switch.
- Connect the Blue Wire to the trailer brake output.
Step 3: Adjust the Power to the Trailer Brakes
- Connect the trailer to the tow vehicle.
- Locate the Manual Slide Knob and Power Knob.
- Apply the Manual Slide Knob and turn the Power Knob until the display reads 4.0.
- Drive the vehicle with the trailer at 25 mph on a dry, level, paved surface.
- Apply the Manual Slide Knob:
- If the trailer brakes lock up: Turn the Power Knob down.
- If the braking is insufficient: Turn the Power Knob up.
- Repeat Step 5 until the power is just below wheel lock-up or at sufficient braking force.
Troubleshooting Guide:
Situation 1: No Display When Brakes Are Applied
- Cause: Poor connection on Power (Black Wire) or Ground (White Wire).
Situation 2: Display Reads Incorrectly
- Cause: Corrosion on the trailer plug or poor connection on the Brake Line (Blue Wire).
Situation 3: Braking is Too Aggressive
- Cause: Power is set too high.
Situation 4: Braking is Too Light
- Cause: Power is set too low.
