The durable Relay with Built-in Fuse 40A is ideal for powering ECU, injectors, ignition coils, and other components, providing essential protection and stable current flow for high-performance applications. Built to handle up to 40A, it ensures efficient power management when wiring multiple components (one relay per wired component).

Each component being wired requires its own relay, making this unit a versatile choice for custom wiring projects. The FuelTech Relay with Built-in Fuse features straightforward electrical connections:

  • 85 – Trigger (FT auxiliary output, activated on ground switch)
  • 86 – Switched 12V
  • 30 – Battery 12V
  • 87 – Output for load (normally open, 40A capacity)

For easy installation, pair it with our Relay Holder Kit, keeping your setup organized and secure.
