BOSS SnowRator Regulator Harness Upgrade

Sealed Replacement Regulator & Connector Kit – For Honda GX390 (Tested)

Developed in collaboration with local snow contractors, this replacement regulator and connector kit was designed to provide a reliable, sealed electrical connection—eliminating common charging issues in harsh conditions.

This kit has been tested and confirmed to work with the Honda GX390 engine platform. While compatibility with the Kohler CH440 is likely due to similar charging circuits, it has not yet been tested. These engines use different wire colors, so be sure to select the correct harness for your specific engine.
