Maypole 7-Way Bypass Relay (Universal Wiring)

The MP3877B is a sophisticated electronic relay designed for vehicles with complex CAN-bus or multiplexed wiring systems. It allows for the safe installation of trailer electrics by drawing power directly from the battery rather than the vehicle's lighting circuit. This prevents the vehicle's ECU from detecting "bulb failure" errors or overloading sensitive factory wiring. It is compatible with almost all 12V vehicles.
