THUNDERMAX Micro Harness Controller Kit — for choppers and custom bikes with separate brake light excludes 2004–2020 Big Dog models

Compact micro harness controller that combines fuse, relay (including starter relay) and signal‑canceling functions in one simple package. 🔧

Provides multiple flasher modes — signal canceling, hazard lights, running lights and turn signal — from a single dual‑filament bulb for simplified wiring and dependable signaling.

Billet 6061 T‑6 aluminum housing and a 7' trim‑to‑fit wiring design keep the unit compact and easy to hide on custom motorcycles.

Relays distribute all power functions, eliminating the need to run large gauge wires to every switch, and weather‑resistant connections provide trouble‑free use in extreme environments.

Compatible with micro switches and intended for choppers and custom bikes with a separate brake light (except 2004–2020 Big Dog models with proprietary hand controls).
