Application & Installation Notes:
This heavy-duty electric brake magnet kit is optimized for trailer backing plates manufactured after June 1992. For ideal on-road safety and balanced stopping force, always replace your trailer magnets in pairs across the same axle. During the electrical connection setup, it is highly recommended to use watertight heat-shrink butt connectors to safeguard the lead wires from moisture intrusion, road grime, and harsh winter road salt contamination.
