Fuse Box

Under the seat on most models. Street Triple and Speed Triple have accessible fuse boxes. Tiger adventure bikes have the fuse box behind a side panel. Blade-type fuses.

Relay Tap Points

  • Power: connect to battery terminals with inline fuse
  • Key switch: W/BN wire at the fuse box for switched 12V
  • Signal wires: verify per model — Triumph uses different color codes than Japanese brands

Notes

  • Triumph wire color codes follow British convention — different from Japanese brands
  • Street Triple has good under-seat space for mounting
  • Tiger models have excellent accessory support with auxiliary power connectors
