Trailer Isolator (5 to 4 – For Use w/4-Wire Trailers)

Description

The NAMZ Trailer Isolator is designed for 2014-2023 Indian Touring models (excluding Scout) and converts a 5-wire motorcycle system to work with a 4-wire trailer. It takes power directly from the battery while capturing signals from the brakes, running light, and turn signals. These signals are processed through a bank of four relays, ensuring that power comes from the battery rather than the factory turn signal module, preventing premature failure of costly OEM components. The isolator provides outputs for left, right, brake, turn, and ground wires. The 4-wire version includes a molded flat 4-pin connector with left/brake, right/brake, run, and ground connections. This setup ensures reliable trailer lighting without overloading the motorcycle’s electrical system.
