CINVEI Trailer Break-Away Kit — Side-Load Break-Away Controller with LED Indicator, Weather-Resistant

The CINVEI Trailer Brakes Break-Away Kit is a side-load breakaway controller system that automatically applies trailer brakes and signals with an LED if the trailer separates from the tow vehicle.

This compact, rugged kit serves as a last-resort safety device for trailers and caravans, designed to stop a detached trailer and alert the driver that the breakaway circuit has been triggered. Built with a weather-resistant plastic housing and a simple color-coded wiring scheme (white = ground, blue = brakes, black = battery), the unit is intended for straightforward fitment and dependable operation when paired with a dedicated trailer battery.

How does the CINVEI break-away controller protect my trailer during a separation?

When a trailer becomes unhitched, the break-away switch interrupts its connection to the tow vehicle and completes a circuit to the onboard battery, instantly engaging the trailer's brakes. The controller is engineered to deliver that brake power reliably and to provide a visible LED indication so you know the system activated.

• Instant brake activation from the trailer battery on disconnection
• LED indicator shows the system has been triggered
• Durable housing resists road debris and moisture

What wiring and installation details should I expect with this kit?

The CINVEI kit uses a clear three-wire color code to simplify installation: white for ground, blue for the brake signal, and black for the battery feed. The side-load switch design mounts to the trailer frame or breakaway box and connects directly to the trailer brake actuator and battery so the system is ready with basic electrical and mounting skills.

• White = ground connection to chassis
• Blue = brake output to the trailer actuator
• Black = positive feed to the trailer battery
• Side-load switch body fits common breakaway box openings

How do the LED indicator and housing improve reliability for long trips?

The unit’s LED gives an immediate visual confirmation that the break-away circuit has been engaged, allowing drivers or passersby to quickly spot the issue. The rugged plastic enclosure shields electronics from dust, rain, and road splash, helping maintain consistent performance in outdoor conditions.

• LED provides quick, visible status feedback
• Rugged plastic housing for weather resistance
• Low-maintenance design suited to routine towing use

Are there any pre-trip checks or battery requirements I should follow?

Because the break-away system relies on the trailer’s battery to apply brakes when disconnected, verifying battery condition and charge before travel is essential. Regularly inspect wiring connections for corrosion, ensure the ground is secure, and test the LED indicator to confirm readiness.

• Confirm trailer battery is charged and in good condition
• Inspect wire terminals and secure ground connection
• Test the LED and switch operation prior to departure

Who is this for: The CINVEI Trailer Brakes Break-Away Kit is intended for caravan, trailer, and utility trailer owners who want a compact, easy-to-install safety controller that activates trailer brakes automatically if separation occurs. It’s well suited for DIY installers and professional fitters who need a straightforward breakaway solution with clear wiring, a visible LED status light, and a durable housing for regular towing use. Remember to pair it with a properly maintained trailer battery and follow local towing regulations when installing and using any break-away system.
