When building a bike, or fully replacing the electrical wiring of an existing motorcycle, a brain box is a good option for a simple, solid and dependable wiring system. Lights are dimmed at starting. The brain boxes with handlebar wiring adapters simplify wiring and make it almost invisible when compared with some other brain boxes on the market. Housing is polycarbonate, waterproof cast with epoxy resin. Max. ambient temperature is 100 degree Celsius and maximum output is 5 Amp. per exit and 3 Amp. for horn. Compatible with miniature pushbutton control knobs that function with super thin wiring. Brain boxes can easily be tie-wrap clamped to frame tubes or similar. All come complete with super clear installation instructions.

Note: Connecting starter motor directly on brain box will cause damage. The H-D starter motor takes 10Amp for the solenoid to switch and requires an additional small automotive relay between starter output of the brain box and the starter solenoid.
Note: Added in 2025 is a gray cable. This is an output for the turn signal LED in the speedo. You can use this output if your speedo has only one LED for both directions.
