• Application: Designed for 2 to 4 trailer brake systems

Tools Required:

• Drill with 1/8" drill bit
• Screwdriver
• Wire Cutter/Stripper
• Wire Crimping Tool
• Circuit Tester

Package Contents:

• Brake Control Unit
• Mounting Bracket
• Mounting Screws (#6 x 3/8") (Qty: 4)

Components Overview:

4. Light Indicators:
   • Green Light: Trailer is connected.
   • Red Light: Brakes are activated (manual control or brake pedal).
   • Flashing Red/No Light: Trailer is not connected.
5. The Green Light uses 10 milliamps; it would take over 5,000 hours to drain the vehicle battery.
6. Weight Limit: Never exceed the Gross Combined Weight Rating (GCWR) recommended by the vehicle manufacturer.

Mounting Instructions:

1. Select a Suitable Mounting Location:

   • Choose a solid surface within easy reach of the driver.

2. Mount the Bracket:

   • Use the mounting bracket as a template and mark the holes.
   • Drill two (2) 1/8" holes at the marked points.
   • Secure the bracket with #6 x 3/8" screws provided.

3. Install the Brake Control:

   • Slide the Brake Control into the bracket.
   • Secure with screws; tighten snugly but do not overtighten.

Wiring Instructions:

1. Black Wire (Battery +):

   • Connect to the positive terminal of the vehicle battery using a 20A circuit breaker.

2. White Wire (Ground -):

   • Connect to a clean, bare metal surface on the vehicle chassis.

3. Red Wire (Stoplight Switch):

   • Connect to the cold side of the stoplight switch (only active when the brake pedal is pressed).

4. Blue Wire (Trailer Brake):

   • Connect to the trailer brake wire at the 7-way connector.

Adjusting Brake Power:

1. Initial Setup:

   • Turn the Power Knob to minimum.
   • Turn the Power Knob 1/4 turn in the + direction.

2. Testing Brakes:

   • Connect the trailer and drive at 25 mph on a dry, level surface.
   • Apply the Manual Slide Knob:
     • If brakes lock up: Reduce power using the Power Knob.
     • If braking is insufficient: Increase power using the Power Knob.

3. Fine-Tuning Power:

   • Repeat the above step until braking is smooth, just below the point of wheel lock-up.

Troubleshooting Guide:

Safety Notes:

• Warm trailer brakes before testing by driving 1/4 mile at 45 mph with light manual braking.
• Adjust power based on load weight and road conditions.
• Do not set power so high that trailer brakes lock up, as this can cause loss of control.

Maintenance:

• Inspect trailer brakes every 3,000 miles or as recommended.
• Adjust brakes as necessary for optimal performance.

Technical Support:

• For technical support and assistance, our team of experts is available to help. You can reach our tech support by visiting www.trailerjacks.com or calling 877-869-6690.
