Common wire colors, fuse box locations, and relay tap points for Kawasaki motorcycles. Always verify with a multimeter before making connections.

Common Wire Colors

These are typical colors across recent Kawasaki models. Colors can vary between model years — always verify with a multimeter.

Fuse Box

Typically under the seat or behind a side panel. Fuse box uses blade-type fuses (10A-30A). Look for the SPARE fuse slot for clean fuse-tap installation. On sport bikes (Ninja, ZX series), the fuse box is usually under the seat cowl.

Relay Tap Points

  • Turn signals: tap the GR (right) and/or G (left) wire at the rear harness connector near the tail
  • Horn: tap the BL wire at the horn relay near the headstock — relay trigger is low-current
  • Ignition accessory: BR wire at the fuse box provides switched 12V for key switch input
  • Always-hot 12V: R wire at the battery or main fuse — use an inline fuse (5A)

Notes

  • Kawasaki uses consistent wire colors across most models from 2018+
  • Sport bikes (Ninja/ZX) have tighter clearances — route wires carefully around the airbox
  • Most Kawasaki fuse boxes have 1-2 spare slots for fuse taps
