Running a high draw electric fuel pump off a switched ignition wire is how dashboards catch fire. This kit gives the pump its own relay-switched circuit fed through a 30 amp breaker, with heavy gauge wire long enough to reach a rear mounted pump, so the trigger wire only has to carry the signal current.

- 30 amp relay with a pre-wired connector.
- 30 amp circuit breaker.
- 8 ft. harness in 10 to 18 gauge wire.
- Crimp terminals and mounting hardware.
- Relay connector has slots so additional relays can be nested together for a clean installation.
- Suitable for electric fuel pumps, cooling fans and electric water pumps.
