5. Setup and Installation
Proper installation is crucial for the effective operation of your CURT Soft-Trac 2 Breakaway System.
5.1 Mounting the Breakaway System
- Select a Mounting Location: Choose a secure location on the trailer frame, near the hitch, that is protected from road debris and moisture. The battery case features a metal mounting bracket with a 3-1/8" hole for easy attachment to the trailer tongue or a jack post.
- Secure the Battery Case: Use appropriate hardware (not included) to firmly attach the battery case to the selected location. Ensure it is stable and will not vibrate loose during travel.
- Install the Breakaway Switch: Mount the breakaway switch to the trailer frame in a position where the 48-inch lanyard can be easily connected to the tow vehicle's hitch or a dedicated attachment point, allowing for a straight pull if separation occurs.

5.2 Wiring Instructions

- Black Wire: Connect to the positive (+) terminal of the 12-volt trailer battery.
- White Wire: Connect to a clean, secure ground point on the trailer frame.
- Blue Wire: Connect to the electric brake wire of your trailer's wiring harness.
- Breakaway Switch Wires: Connect the two wires from the breakaway switch to the breakaway system's control unit as per the included wiring diagram.

6. Operating Instructions
Once installed, the system operates automatically.
6.1 Connecting the Lanyard
Before each trip, attach the breakaway switch lanyard to a secure point on your tow vehicle's hitch or frame. Ensure the lanyard has enough slack to allow for turns but is taut enough to pull the pin if the trailer separates.
6.2 System Activation
In the event of a trailer separation from the tow vehicle, the lanyard will pull the pin from the breakaway switch. This action will send a signal to the trailer's electric brakes, applying them immediately to bring the trailer to a safe stop.
7. Maintenance
Regular maintenance ensures the reliability of your breakaway system.
- Battery Check: The 12-volt battery should be checked and sufficiently charged prior to every trip. The included charger helps maintain the battery's charge.
- Lanyard Inspection: Inspect the breakaway lanyard and pin for any signs of fraying, corrosion, or damage before each use. Replace if necessary.
- Switch Functionality: Periodically test the breakaway switch by pulling the pin to ensure the trailer brakes activate. Reinsert the pin to disengage the brakes.
- Wiring Inspection: Check all wiring connections for corrosion, loose terminals, or damaged insulation. Repair as needed.
- Battery Case: Ensure the battery case is securely mounted and free from cracks or damage that could expose the battery to elements.
